Luigi

"Hey, Bro! Everyone left me behind! I had to hustle to get up here!"

- Luigi

Luigi (Japanese: ルイージ, Ruīji) is Mario's younger, taller twin brother. Luigi has assisted and fought alongside his brother on many occasions. Throughout his life, he has lived in Mario's shadow, developing both cowardly and heroic tendencies. Mario Bros. marks his first appearance in a Super Mario arcade game. Originally a color swap of Mario, Luigi was created to facilitate a second player option. Since the two player mode was dropped from most Super Mario games beginning with Super Mario Land, Luigi had gained his own identity and personality.

Luigi was born when Shigeru Miyamoto set out to create Mario Bros. after being told Mario resembled a plumber, a notion he wanted to officially establish. For this particular adventure, however, Miyamoto wished to incorporate a two-player mode. : Miyamoto's answer to Joust 's stork-riding Player 2 was Luigi, Mario's green-clad younger twin brother with whom he could compete or cooperate with. With 2-player mode in mind, Nintendo and publishing companies such as Atari gave Luigi immediate publicity, making him the star of multiple advertisements for the game.

''Mario Bros.
Luigi's first playable appearance was in Mario Bros., where he is simply a palette swap of Mario with the same controls and abilities. There are no other differences in physical appearance. In the game, Luigi and Mario are portrayed as plumbers, who are trying to rid the sewers where they are working from Shellcreepers, Slipices, and many other monstrous creatures.

It is interesting to note that Luigi was played by an unknown actor in a live-action commercial for the Atari 2600 version of Mario Bros..

''Super Mario Bros.
In Super Mario Bros., after Mario and Luigi fought the monsters of Mario Bros., they returned to the Mushroom Kingdom where they were told by the Mushroom King that the evil king Bowser had kidnapped Princess Toadstool and her Mushroom Retainers.

Mario and Luigi then went to save the kidnapped Princess Toadstool and rescue her from the king of Koopas. The Mario brothers had to travel 8 different worlds of the Mushroom Kingdom, each world complete with its own challenges that Luigi and Mario had to face. The brothers fought many enemies, defeated Bowser, and saved the princess along with the Mushroom Retainers. In this game, Luigi had the same jumping powers, same traction, and the same running speed as Mario.

''Super Mario Bros.: The Lost Levels
Later, in Super Mario Bros.: The Lost Levels, the Mario brothers were once again called to save Princess Peach from the Koopa Troop. Bowser had set up many more traps for the Mario Bros., but nevertheless, they prevailed and saved the princess yet again. This time, Luigi could jump higher and further than Mario, but he had less traction.

''Super Mario Bros. 2
Luigi was one of four characters in Super Mario Bros. 2 that found themselves in a very strange world called Subcon that was under attack while dreaming. The next morning, the four friends decided to go on a picnic, and happened to stumble upon the strange world they had dreamed of. They found that everything they had been told in the dream was true; it was under the rule of the evil Wart. Luigi and his three friends confronted Wart and his forces, defeating them one by one. The four heroes traveled to Wart's lair and battled him by choking him with Vegetables. Wart finally fell and the four heroes were able to release the Subcons. At the end of the game, it was revealed that the events of the game was just Mario's dream.

In Subcon, Luigi could jump higher than all of his friends, and was the second weakest in the group.

''Super Mario Bros. 3
Bowser now traveled with a massive Airship and his children in Super Mario Bros. 3. He transformed all of the kings in the world into odd creatures and then proceeded to make his children kings of all the different lands.

Mario and Luigi were called upon by Princess Toadstool to save the day again. The brothers went on another adventure to save not only the Mushroom Kingdom but the Mushroom World. Luigi and Mario faced many challenges and obstacles, from the Koopalings' Airships to the scorching climate of Desert Land to the chilling weather of Ice Land. The brothers defeated every enemy that confronted them. After defeating the Koopalings and turning the kings back to their regular state, the brothers found out from a letter sent from Bowser that Bowser kidnapped the Princess while they were away. The Mario Bros. went to the frightening home of Bowser, Dark Land, to save the kidnapped Princess Peach.

After saving the princess once again from Bowser, the plumbers returned to their home in the Mushroom Kingdom.

''Super Mario World
After the events of Super Mario Bros. 3, Princess Toadstool and the Mario Brothers went on a vacation to Dinosaur Land in the game Super Mario World. Mario, Luigi and Toadstool hopped on a hot air balloon to get to the tropical island. Luigi had found a magical Feather on the island that allowed anyone who grabbed it to turn into cape form. Mario and Luigi flew around Dinosaur Land. When they returned, they found Toadstool missing again. Bowser and his children had kidnapped Princess Toadstool along with seven Baby Yoshis and trapped any Yoshis he met in eggs. Luigi, Mario, and Yoshi traveled the many different areas of Dinosaur Land in search of the princess. The brothers used Yoshi as their trusty steed throughout their adventure. After defeating all seven of the Koopalings the Mario Bros. uncovered Bowser's secret hideout. Ready for anything, the brothers and Yoshi charged to Bowser's Castle. After fighting many enemies, the brothers finally confronted Bowser and his Koopa Clown Car. Using the Mecha Koopas that Bowser tossed down at the brothers against him, the Mario brothers were able to defeat Bowser once again and rescue the princess and the seven Yoshi Eggs.

''Super Mario 64 DS
Although Luigi did not appear in Super Mario 64, he did appear in its remake: Super Mario 64 DS. Luigi, along with Mario and Wario, entered Princess Peach's Castle after she invited them. Bowser and his Koopa Troop shortly then took over the castle and captured each of the plumbers. Luigi was locked behind a door, and the key to the said door was guarded by King Boo. Eventually, Yoshi, who was sleeping on the castle roof and therefore didn't get captured by Bowser's troop, managed to rescue Mario, who then managed to find King Boo's hideout and defeat the Boo's leader in battle, allowing him to get the key needed to free Luigi. While only Luigi can get several stars, several Luigi Caps can be found on a few courses. The Luigi caps allowed the bearer to mimic Luigi's appearance and abilities perfectly, excluding his voice. Every level in the game would have a Luigi Cap appear once Luigi was rescued. Luigi was also the only character who could save Wario from Chief Chilly's grasp, as he was needed to walk through a mirror using his invisibility flower to get to Wario's painting.

Luigi's Special Ability from a Power Flower was to become invisible. This ability allowed him to evade enemies and run through certain walls. If the Luigi performed a backward somersault, Luigi would spin in midair. This effect was similar to jumping on a Fly Guy. Luigi also can Scuttle, and he could also run on water for a short period of time.

All of Luigi's mini-games from the Rec Room (which later re-appear in New Super Mario Bros. in mini-game mode, along with most of the other mini-games) revolve around poker and casino games. Luigi acts as the dealer in all of the card games, and he does not wear his usual attire, instead wearing a white shirt with a black vest and a green bow tie.

''New Super Mario Bros.
Once again, in New Super Mario Bros., Princess Peach was kidnapped and had to be saved by Mario. This time, she had been kidnapped by Bowser Jr., Bowser's son. Mario went to save the princess with a little help from Luigi. Mario and Luigi traveled to the many areas of the Mushroom Kingdom, fighting the many enemies that Bowser and Bowser Jr. put in their way. At the castle in World 8, Mario and Luigi ended up fighting Dry Bowser (an undead version of Bowser). After being tricked into believing that they had finally defeated Bowser, Bowser Jr. stole Peach and the Mario Bros. had to follow him to Bowser's Castle where they finally confronted a now-revived, bigger Bowser and Bowser Jr.. Again, the Mario Bros. defeated Bowser and his son and rescued Peach once again. After the credits rolled, the secret code to let Luigi play (++=Luigi) was revealed. Luigi will say his name to indicate that the code worked correctly. His role was the same as Mario's. Luigi also appeared in this game's multiplayer mode where he battles Mario for Stars.

''Super Mario Galaxy
Luigi appeared in Super Mario Galaxy. When Bowser abducted Peach's Castle, Luigi and the Toad Brigade were apparently inside. However, they all escaped and got lost in space. Luigi was imprisoned in the Ghostly Galaxy. Mario must come and rescue him, after which he will help Mario in a handful of missions, including collecting stars (although, he gets lost every time and must be rescued). After collecting three stars, Luigi left the rest up to Mario.

After the player collected all 120 Power Stars and defeated Bowser again, the player had to play as Luigi in order to collect the next 120 Power Stars. There were several differences when playing with Luigi: his run was faster, but took more time to build up speed; it was harder for him to stop running; he could jump higher and further; and the air meter dropped faster while spinning underwater. Additionally, Cosmic Luigi was faster and more intelligent than Cosmic Mario while racing.

In Luigi's playthrough of the game, Mario would be absent, resulting in two Luigis. Notably, the playable Luigi was a little shorter and had a different head shape than the NPC Luigi. His clothes were also slightly darker. The NPC Luigi referred to the playable Luigi as "me" as he called Mario "bro" in his letters. Also, Rosalina called the NPC Luigi his "twin".

''New Super Mario Bros. Wii
Luigi appears in New Super Mario Bros. Wii. The game begins at Peach's Castle, where the princess's birthday is being celebrated. A large cake suddenly arrives, which is revealed to be a trap; Bowser Jr. and the Koopalings burst out, then kidnap Peach. Mario, Luigi, Blue Toad, and Yellow Toad, all attendees of the party, venture through the Mushroom Kingdom to rescue her, this time not only with his brother, but with the two Toad companions. Later in the story, after Bowser is defeated, he gives Mario and Peach his hot-air balloon, which they take and leave Luigi. Blue and Yellow Toad take him in theirs instead. Also, When a player hits the Super Guide Block Luigi will guide the player through the level the player is stuck on.

''Super Mario Galaxy 2
"Hey, Bro! I'm all over the place these days, exploring the universe!"

- Luigi

Luigi appears in Super Mario Galaxy 2 where he often teams up with Mario and Yoshi to save the universe from being ruled by Bowser, and to retrieve the Power Stars.

As a playable character, he is controlled the same way as in Super Mario Galaxy and is still unlockable. Luigi can be found at the beginning of some levels. Walk over to him and talk to him. He will then ask the player if he can jump in. In this game, like in Super Mario Galaxy, he can jump higher than Mario, but is harder to stop. Also, completing levels with Luigi will unlock staff ghosts for as many missions as the player is able to complete as Luigi.

Once the player completes Bowser's Galaxy Generator, they can alternate between using Mario or Luigi, via the Starship Mario; the Mailtoad will have mail from Luigi, telling the player that Mario can now switch with Luigi.

This game differs from the first game in that Mario can switch to and from Luigi while under the same game file, as opposed to leaving the game file and switching from Mario to Luigi or vice versa via a button on the game file selection screen.

''Wrecking Crew
Luigi was once again the second player in Wrecking Crew. Luigi's sprite was still a palette swap of Mario's, but this time Luigi was dressed in purple. In this game, Mario and Luigi worked on a demolition site. The goal was to break down every stone wall on each stage. Defeating enemies in this game was not easy, as Mario and Luigi's regular hammer dealt them no damage. However, it could make Foreman Spike fall down if one of the Mario Bros. could hit him with it. If an enemy wanders underneath a drum, Mario or Luigi could trap them by causing the drum to fall.

''Super Mario Bros.: Peach-hime Kyushutsu Dai Sakusen!
The first animated Luigi appeared in the anime movie Super Mario Bros.: Peach-hime Kyushutsu Dai Sakusen! ("The Great Mission to Save Princess Peach"), where he was voiced by Yuu Mizushima. For some reason, he was mis-colored in the movie as wearing a blue cap and overalls and a yellow shirt (and a red shirt in the promotional artwork for the anime), although it may be worth noting that, at the time of Peach-hime Kyushutsu Dai Sakusen!'s creation, Luigi had not yet been given a consistent palette and his current color scheme had not been introduced in-game. The anime also marked the first time Luigi was ever given a personality; Peach-hime Kyushutsu Dai Sakusen! depicted Luigi as very greedy, typically thinking only of profits and characterized by his pick-axe and shovel, both of which he used to mine for Coins. (As a matter of fact, Luigi often left adventuring with Mario and Kibidango to search for Coins, though he usually ended up helping them progress in various ways through his miserly efforts.) Luigi in the anime was also noticeably more serious and less dreamy than Mario, and he seemed to lack his brother's almost otherworldly connection to Princess Peach.

Super Mario anime series
Luigi also appeared in another anime, the Super Mario anime series, which depicted as wearing his traditional blue and green clothing. Luigi only appears in the last story of the Super Mario anime series film, Shirayuki-hime (Snow White) appearing just in time to save Mario and Princess Peach from Bowser, who was portrayed as the stories' wicked queen.

DIC cartoons


Luigi appeared in all ninety-one episodes of the three cartoon series produced by DIC Entertainment, though Mario only appeared in ninety episodes.

''The Super Mario Bros. Super Show!
On the tv show The Super Mario Bros. Super Show!, Luigi, portrayed by Danny Wells, is seen living in Brooklyn together with Mario in the live-action segments. Like his brother, Luigi works as a Plumber, running Mario Brothers Plumbing together with him. The episode Plumbers Academy shows that he graduated from the Brooklyn Plumbers Academy together with Mario. The live-action segments show the two as having gained a reputation for their plumbing skills, even being awarded the title Plumbers of the Year in the segment of the same name. In the cartoon segments of the show, Luigi regularly joins his brother in various adventures in the Mushroom Kingdom. The Super Mario Bros. Super Show! is the origin of Luigi's cautious, easily-frightened personality which Nintendo later brought into the games as well, including Luigi's Mansion.

''The Adventures of Super Mario Bros. 3
Luigi is played by Tony Rosato in the two cartoon follow-ups to the Super Show: The Adventures of Super Mario Bros. 3 and Super Mario World. The former is amost exactly like the Super Show, except the Koopa Kids join their father in making trouble for Luigi and the others.

In episode The Beauty of Kootie, Casanova Koopa is what Luigi turned into to trick Kootie Pie into letting Toad, Toadstool, and the King of Desert Hill free. Kootie tricked Mario by having her brother Cheatsy change her into a human so she could flirt with him and distract him in order to carry out their plan. After the trick was revealed and the Mario brothers got away, Mario used a swiped Magic Scepter to transform Luigi into Kootie's "dream reptile" as a distraction. The trick worked for awhile, but after Casanova Koopa tricked Kootie into releasing the prisoners and Kootie started kissing him, she accidentally activated her wand. Subsequently, Luigi was reverted into his true state, which made Kootie Pie scream.

''Super Mario World
The Super Mario World television series shifts the setting from the Mushroom Kingdom to Dinosaur World, but once again, is relatively the same as the earlier cartoons, with Mario, Luigi, Princess Toadstool and Toad stopping the evil plots of King Koopa and his Koopa Kids. However, the heroes are now aided by the dinosaur Yoshi, who was actually discovered by Luigi, who found a Yoshi Egg after falling down a waterfall. When he hatched, Yoshi affectionately called Luigi Mama Luigi.

''NES Open Tournament Golf
Luigi has not appeared in every game of the Mario Golf series. His first appearance was in NES Open Tournament Golf. Luigi's caddy was Princess Daisy.

Mario Golf (Nintendo 64)
Luigi reappeared in Mario Golf (Nintendo 64). He was one of the first characters that could be unlocked. He could be unlocked by beating him on the "Get Character Mode". He had a unique course (in the sense that it was the only course in the game set up like a mini-golf course) named Luigi's Garden. He had a drive of 220 yards and his shot was "Fade".

Mario Golf (Game Boy Color)
Although Luigi was not a default character in Mario Golf (GBC), he was playable via the Transfer Pack like many of the characters of its Nintendo 64 counterpart.

''Mario Golf: Toadstool Tour
Luigi made his fourth Mario Golf series appearance in Mario Golf: Toadstool Tour as a default character. In the game opening, he and Mario were admiring a trophy when Princess Peach and Princess Daisy called to them saying that it was time to tee. Luigi, along with his brother and the two princesses, were shown making perfect tees, making Wario and Waluigi envious. After a series of mess ups, Wario and Waluigi ended up giving Bowser a black-eye with their golf ball. Enraged, Bowser started chasing them in his Koopa Clown Car, throwing Bob-ombs at them. He eventually trapped them, threatening to drop a bomb right on them. Mario, who had Luigi, Daisy, and Peach right behind him, hit the golf ball, making it knock the bomb out of Bowser's hand, ultimately resulting in an explosion claiming Wario, Waluigi, and Bowser as its victims. Luigi, along with the other three who were with him, stood there shocked, not knowing what caused the explosion.

''Mario Golf: Advance Tour
Luigi, although he was not a default character, he was playable in Mario Golf: Advance Tour through linking the Game Boy Advance and the Nintendo GameCube.

Club Nintendo
Luigi also made several appearances in the Club Nintendo comic series, usually as a companion of his brother Mario. In the story "Super Mario: Im Rausch der Geschwindigkeit", however, Luigi worked as a policeman and actually imposed a fine on Mario when the latter was violating the speed limit of Brooklyn while riding Yoshi. Luigi also insisted on being called "Officer Luigi."

''Super Mario Adventures
The Super Mario Adventures comic serial's depiction of Luigi, oddly, features him in an opposite portrayal to his personality in the games and cartoons. In the first installment, Luigi wants to eat his lunch first and whines about his hunger as Mario continues with their plumbing job. Later, Luigi is actually willing to go into a Ghost House that Bowser has set as a trap for them, despite Mario's warnings, and then ends up going in anyway when Bowser lets loose the scent of a giant hunk of aged provolone cheese. Also worth noting is that Luigi disguises himself as Princess Peach to infiltrate the Koopalings' hideout at one point, a strategy he would later use in Mario & Luigi: Superstar Saga.

''Super Mario Kart
Luigi appeared in Super Mario Kart as a playable character. He was classified as "medium" in every category (acceleration, top speed, weight, and handling) along with Mario. Super Mario Kart was one of the few games in the Mario Kart series that did not have a course based on Luigi. When he was a computer-controlled character, he had a tendency to use star power in races.

''Mario Kart 64
Luigi reappeared in Mario Kart 64, yet again as a playable character. He was classified as a middleweight character, along with Mario. This was the first appearance of his course, Luigi Raceway, which was a part of the Mushroom Cup.

''Mario Kart: Super Circuit
Luigi was playable in the third game in the Mario Kart series with his speed and weight being average. Another version of Luigi's course appeared in the game, as a part of the Lightning Cup.

''Mario Kart: Double Dash!!
Luigi appeared in Mario Kart: Double Dash!!. He was a medium weight character and Mario's default partner. His special item was Green Fireball and his Kart was the Green Fire. Once again, he had a course named Luigi Circuit, and his mansion also appeared as a battle course, as well as making a cameo in the background of the Luigi Circuit course.

''Mario Kart DS
Luigi appeared once again as a middleweight character in Mario Kart DS. His karts were the Poltergust 4000, the Streamliner, and the Standard LG. His mansion reappeared as a course in the Mushroom Cup (different from the Mario Kart: Double Dash!! battle course), as well as the Luigi Circuits from Mario Kart: Super Circuit and Mario Kart: Double Dash reappearing in the Leaf Cup and the Shell Cup, respectively.

''Mario Kart Wii
Luigi appeared as a middleweight character again in Mario Kart Wii, and could use a variety of karts and bikes. The only course based on Luigi in this game was Luigi Circuit, the first course of the Mushroom Cup.

Luigi featured a small speed boost, but his best bonus was the weight stat.

''Mario Kart Arcade GP
Luigi also appeared in the first Mario Kart game for the arcade, Mario Kart Arcade GP. His and Mario's special character items were the Star, the Fireball, the Hammer, and the Chain Chomp. Unlike most other Mario Kart games, Luigi did not have a course based on him in the game.

''Mario Kart Arcade GP 2
Luigi appeared again in the second Mario Kart game for the arcade. He was an all-around character along with Mario, Pac-Man, and Waluigi. Unlike most other games in the series, he did not have a course.

''Mario is Missing!
In Mario is Missing!, Mario was kidnapped by Bowser, and it was up to Luigi to find him. During his quest, Luigi learned about geography, battled Bowser's seven children, and got help from Yoshi while traveling across the real world to find Mario. In the end, he saved Mario. Then, the Mario Bros. loaded Bowser into a cannon and fired him into the snow. Bowser froze instantly and split in half. However, this ending only applied to the SNES version of the game. This game marked Luigi's solo-adventure debut and was the only solo adventure for Luigi until 2001 when the game called Luigi's Mansion making his second time as a main character in the Mario series.

Super Mario Bros. film
Luigi was played by John Leguizamo in the Super Mario Bros. movie, which is drastically different than the games. Luigi is much younger than his brother Mario, who raised him from infancy after their parents died, and took him as his apprentice in the family plumbing business in Brooklyn. In the film, Luigi meets Daisy, who was brought to Earth from a parallel world by her mother, who was fleeing the evil King Koopa. They fall in love, but Daisy is kidnapped and brought back to the dinosaur world, since Koopa needs her to unite the dimensions, allowing him to take over the human world, as well as his own realm. Luigi and Mario follow the kidnappers and work to rescue Daisy, stop Koopa and free the dinosaur realm. In the end, Luigi has to return with Earth with Mario, while Daisy remains in her world, and they part with a kiss. Some time later, Daisy returns to Earth and requests Mario and Luigi's help with an unknown urgent matter back in her realm, and they eagerly accept.

''Mario & Wario
In Mario & Wario Luigi appeared as the game's goal and the player had to navigate the level to get to Luigi.

''Hotel Mario
Luigi is one of the main characters in the game Hotel Mario. Princess Peach was retained as a "permanent guest" by Bowser, who turned the Mushroom Kingdom into his own personal resorts. Eventually, Luigi and Mario destroyed each of the seven Koopaling Hotels. They then defeated Bowser at his own palace and rescued the princess. Luigi was controlled by the second player, his sprite being a palette swap of Mario. This was Luigi's only run on the Philips CD-i.

''Super Mario RPG: Legend of the Seven Stars
Luigi only made several cameos in Super Mario RPG: Legend of the Seven Stars. In Star Hill, Luigi made a wish: he wanted to be a good plumber, just like his brother. In the ending of the game, Luigi was the leader of the parade. Luigi also hosted the manual of Super Mario RPG. A screenshot from the beta version of the game showed Luigi (along with Mario and Mallow) attending a banquet hosted by Valentina.

''Super Mario World 2: Yoshi's Island
In the beginning of Super Mario World 2: Yoshi's Island, Baby Mario and Baby Luigi are shown being delivered to their mother and father's home by the Stork. However, Baby Luigi is snatched away by Kamek and taken to Baby Bowser's castle. His kidnapping is the primary reason for Baby Mario and the Yoshis to embark on their adventure in this game. At the end of the game, Baby Luigi is rescued from Baby Bowser. After the credits, he and his brother are brought to their parents, who discover the two on their doorstep.

''Yoshi's Story
He made a small cameo in Yoshi's Story in the level Torrential Maze of the second world. His name was printed in the background of the stage.

''Yoshi's Island DS
Baby Luigi appears again in Yoshi's Island DS. Here, he is one of several babies that are kidnapped by Bowser and Kamek in their search for the Star Children. He is eventually rescued by Baby Mario, Baby Peach, Baby Donkey Kong, Baby Wario and the Yoshis at the end of the game. After his rescue, Baby Luigi is revealed to be one of the Star Children.

Mario Party series
Luigi was apart of the main cast in the Mario Party Series and appeared in every game. Along with his brother, Luigi wanted to steal the spotlight and become the Superstar. In the earlier Mario Party games his character color was green but changed to blue in Mario Party 4. In Mario Party 2 and 3, his favorite item was the Skeleton Key, and his Duel Mode partner was the Goomba. In Mario Party 3, Luigi was the only character to have a different Star Stamp (5 to be exact) and had every single one except for mischief and beauty. In Mario Party 7, he shared his Character Orb with Mario, the Fireball Orb. Luigi's partner in these games was usually his brother, Mario and whenever he threw an orb, it has the L symbol.

Super Smash Bros. series

 * Main articles: SmashWiki:Luigi (SSB), SmashWiki:Luigi (SSBM), SmashWiki:Luigi (SSBB)

Luigi was a secret (unlockable) character in the fighting game Super Smash Bros. for the Nintendo 64. He was unlocked by beating Bonus stages as all eight of the default characters, and then beating him in a fight. Despite being unlockable, he always fought alongside Mario in Stage 4 of 1-P Mode. He briefly appeared (alongside all unlockable characters) in the opening. He also made a brief appearance in the How to Play tutorial.

He also appeared as a secret character in Super Smash Bros. Melee, the sequel for Super Smash Bros. To unlock him, one had to play the first level of Adventure Mode with a 2 in the "seconds" area of the remaining time. If done correctly, there would be a short cutscene with Luigi kicking Mario off the stage. The player then had to battle Luigi in Mario's place. If Luigi was beaten in less than a minute, Luigi would appear again to challenge the player if the player completed Adventure mode. Alternatively, the player can participate in 800 vs. matches. The winner of the 800th match will be challenged to a fight as above.

He also appeared in Super Smash Bros. Brawl, as an unlockable character once more. To unlock him, the player had to play 22 brawls, complete Classic mode without using continues, or simply get him to join the player's party in The Subspace Emissary. Luigi's white color scheme in Super Smash Bros. Melee and Super Smash Bros. Brawl resembles Luigi's colors in Super Mario Bros.. He was strong, had fast attacks, and was a middleweight. However, he had the lowest traction and very slow movement in both air and ground. He also seems to be more prone to tripping than all the other fighters in Brawl. Also, Luigi seems to be a bigger coward in Brawl (based on his voice effects) than in Super Smash Bros. and Super Smash Bros. Melee.

In Super Smash Bros. and Super Smash Bros. Melee, Luigi's voice is just a high pitched variation of Mario's voice. In Super Smash Bros. Brawl though, his voice sounds just like his basic voice in many Mario series titles.

Solid Snake Codec Conversation

 * Snake: That guy with the mustache...
 * Colonel: Ha. You mean the "King of Second Bananas"?
 * Snake: Hey, that's Luigi! Show him a little respect!
 * Colonel: Look at that pale skin. He's been living in his brother's shadow for too long.
 * Snake: That's a low blow, Colonel!
 * Colonel: Face it, Snake! Once a kid brother, always a kid brother!
 * Snake: Colonel, what's gotten into you?!
 * Colonel: La li lu le lo. La li lu le lo. La li lu le lo.
 * Snake: Colonel, snap out of it! Colonel!! COLONEL!!!!!!!!!

Role in the Subspace Emissary
Luigi first appeared where he pretends to threaten and attack on-coming Waddle Dees. They were harmless and made no move to attack him, but he was frightened by them, nonetheless. Then, out of nowhere he was attacked from behind by King Dedede, who slammed Luigi with his mallet, sending him flying into the air. After he came back down, he became a trophy. King Dedede placed him on the road as bait for Wario, who was coming down the road. Wario took the bait, and Dedede managed to steal the princess and Ness trophies along with Wario's Cargo.

Dedede placed a special badge on Luigi, Ness, and the princess, though the princess's badge was knocked off when Bowser flew off with the princess in his Koopa Clown Car and was later swallowed by Kirby. Later, when Tabuu turned everyone into trophies, the badges turned Luigi and Ness back into living creatures. The badges had the power to bring trophies back to life. Luigi and Ness afterward turned King Dedede back to life. The unlikely trio set off to help out Mario, Donkey Kong, Samus, Fox, Link, Yoshi, Pikachu, Captain Falcon, Marth, Mr. Game & Watch, Falco, Pit, Captain Olimar, Lucas, Diddy Kong, the Pokemon Trainer, and Ike. Luigi, along with Ness, then watch Dedede fight Bowser, and later help him convince Wario to join them. After they turned everyone back to normal, they all fought Tabuu.

Fireball


Luigi used green Fireballs in Super Smash Bros., Super Smash Bros. Melee, and still used it in Super Smash Bros. Brawl. Although the move was called Fireball, the same name as Mario's move, it differed slightly in both appearance and effect. Luigi's fireballs were green, matching his choice of clothing, and the fireballs were not affected by gravity (unlike Mario). This meant the fireballs will always go straight and won't bounce on the ground (unless it is ricocheted by the enemy). However, other than that, nothing else was changed. Kirby gains the ability to use Green Fireballs when he inhales and copies Luigi.

Green Missile


The Green Missile is Luigi's side special move in Super Smash Bros. Melee and Super Smash Bros. Brawl. When executed, Luigi flies like a rocket across the stage, smashing into any other characters and burning them. Luigi is able to charge this move up, which will allow him to fly farther and harder than usual. This would cause more damage to the opponent, sometimes rocketing the foe into the skies. In Brawl, Luigi can hold the charged Green Missile attack until he takes damage from an opponent. Green Missile is actually a better horizontal recovery than his Super Jump Punch attack, because Luigi's Super Jump Punch can only go straight up. This attack compensates for his slow lateral air speed. The attack is very similar to Pikachu's Skull Bash attack, as stated by Luigi's trophy. Luigi's Green Missile has a 12.5% chance of overpowering and going too far and causing more damage to his opponents (in Brawl a misfire didn't go as far as in Melee, making it less risky).

Super Jump Punch


The Super Jump Punch is a jumping move Mario, Luigi, and Dr. Mario can perform in the Super Smash Bros. series. It is executed by pressing while holding  upwards at the same time. When Luigi performs it, he jumped forward like Mario in the original Super Smash Bros., but he jumps straight up in Melee and Brawl. Therefore, his Green Missile is usually a better recovery move. When Luigi performed it without being adjacent to the opponent, only 1 coin flies out of the enemy and only 1% damage is dealt. But if Luigi does this adjacent to the enemy, the enemy becomes cloaked in fire and receives up to 25% damage. If done perfectly in the original Super Smash Bros., the opponent flies away into the background and might get KO'd as a result. Luigi's helpless falling state was the same as Mario's in the first two games, but the helpless animation was completely different in Brawl. Luigi would become seemingly top-heavy and get his head stuck in the ground after performing his Super Jump Punch in Brawl. This leaves Luigi defenseless and wide open for an attack for a short period of time. If used correctly, the Super Jump Punch could be a Meteor Smash.

Luigi Cyclone


Luigi Cyclone was a special move that Luigi can perform in Super Smash Bros., Super Smash Bros. Melee, and Super Smash Bros. Brawl. After pressing while tilting  in the down position, Luigi would spin around in similar fashion to Mario's Mario Tornado. He would pull in nearby opponents, spin them around, severely damaging them in the process, and then fling them in the air, which will leave them open for more attacks. However, the move takes a while to use. Because of its lack of effect on a single opponent, the move was best used when surrounded. Also Luigi Cyclone had the ability to move faster than Mario Tornado making it ideal if characters are far from Luigi. In all three games, the cyclone allowed Luigi for vertical movement if is pressed repeatedly. However, in Brawl, Luigi could fly a lot farther up. The Cyclone was also changed in Brawl to make it more similar to the Mario Tornado, i.e. it would suck in foes instead of just launching them away and also it's much easier to gain height.

Negative Zone


Negative Zone was Luigi's Final Smash in the game Super Smash Bros. Brawl. It was a rather bizarre Final Smash. After Luigi broke open the Smash Ball and utilizes it, he started dancing around in a strange, almost hypnotic way, and a large green circle appeared on the stage, which had a fairly large radius. Everything in the circle was altered to look like a negative or inverted image, hence the name. Any opponents caught in this circle would be affected by a variety of effects, such as uncontrollable taunting, being more vulnerable to KOs, sleeping, and even constant tripping. Even airborne opponents are affected by this move, which can easily stop them from recovering. It doesn't affect teammates, however (unless team attack is ON).

Opponents could escape from the circle and possibly avoid the effects after leaving the circle. They would be affected while the green circle is still on the stage, and will stay affected a little bit after the circle disappears. Luigi remained to be able to move at full speed, which gave him a clear advantage over his opponents for a short period of time. The effects wore off after a while, when the green circle started to shrink. It was stated in Luigi's Final Smash trophy that Negative Zone was a sorcerer's magic attack that was fueled by his dislike of being in his brother's shadow.

The effects were:
 * Drastically reduced attack power
 * Greater launch distance when hit
 * Increased likelihood of slipping
 * Steady increase in damage percentage
 * Flower growth on head
 * Dizziness
 * Uncontrollable taunting
 * Sudden sleepiness
 * Decreased movement speed
 * Tumbling midair (the player couldn't use his/her midair jump)

Dash Attack
If the player presses while Luigi was running at full speed, he will perform a dash attack. His dash attack involves doing repeated hits to inflict damage on opponents. Most of the hits are weak, but the last hit tends to have more knockback than the other hits (although that is easier to notice in Brawl). This move appeared in all three installments of the Super Smash Bros. series.

Mario Tennis series
Luigi also appeared as a regular occurring character in the Mario Tennis cast. Luigi was an All-around tennis player like his brother. Luigi also gained a rival by the name of Waluigi in Mario Tennis. In Mario Power Tennis, Luigi's Mansion appeared as a court. Luigi's Offensive Power shot was the Squeaky Mallet, and his Defensive Power Shot was the Poltergust Return. In the cut scenes of Mario Power Tennis, Luigi usually appeared playing alongside with his brother, Mario, on the court. A specific cutscene with Mario and Luigi played when Luigi wins a championship. Luigi wove around his trophy and Mario walks up, congratulates him (slapping him on the back and saying things like "Good Job"), meanwhile stepping on his foot. Luigi's taunt in Mario Power Tennis was to wave his arms and say "Luigi Time!". Also, in Mario Power Tennis, Luigi discovers the secret of what's under a Shy Guy's mask.

''Paper Mario
During the events of Paper Mario, Luigi was left to protect and maintain his home while his brother pursued the Star Spirits. Luigi spent most of his time lamenting his own inactivity, begging for Mario to take him along and practice for future quests. With all his downtime, Luigi also built a basement in which he kept a secret diary where he wrote about various things, such as how he disliked being left out of adventures with his brother. One notable entry in his diary had him dreaming about starring in his own game, foreshadowing his next solo quest, Luigi's Mansion. After Mario gets the Ultra Hammer and Ultra Boots, Luigi could be found outside, sitting on a Metal Block or very high Brick Block respectively. Mario could use his new moves to break the blocks, triggering some humorous dialogue. He also led the parade in the end credits, very much like in Super Mario RPG.

Paper Mario: The Thousand-Year Door
While Mario saved Princess Peach and collected the Crystal Stars in Paper Mario: The Thousand-Year Door, Luigi also had a mission of his own. After every chapter in the game, Mario could hear Luigi's story in Rogueport. When telling Mario the story, Luigi constantly exaggerated to make the story better and to make himself sound much more heroic; Luigi's partners, who generally hated him and only traveled with him because Luigi owed them a debt, almost always secretly told Mario what really happened. Later, Luigi got interviewed and five Super Luigi books were sold. Luigi's adventure involved rescuing Princess Eclair of the Waffle Kingdom from the Chestnut King. Luigi's story sounded extremely similar to Mario's in most aspects. He usually messed up during his adventure, such as accidentally knocking his partner Blooey the Blooper into the lava.

He also appeared in the audience when in battle. He cheered Mario on during the final battle with the Shadow Queen; one of the word bubbles in that battle reads "YOU GO, BRO!" in green letters. He also appears in Glitzville when Mario is fighting some wrestlers, like Rawk Hawk. His fan club, whose members include Toadia, a Toad from Petalburg, was also given two mentions in the game. The "L Emblem" Badge changed Mario's clothes to Luigi's. In the log for the enemy Iron Cleft states that the Cleft in the green shoes was younger, probably a reference to Luigi. Pennington constantly mistook Mario for Luigi until almost the very end of the game. Lastly, it is worthy of note that Luigi's silhouette was the first of the many white character silhouettes who walked across varying areas of the screen during the game's ending credits, continuing Luigi's past RPG roles as a parade leader.

''Who's this guy? ...Come on, you really need to ask me that? Gimme a break! That's your brother, Luigi! But...I wonder why he's here? I'm sure he'll tell you if you ask him.''
 * Tattle information

''Super Paper Mario
In the game Super Paper Mario, Luigi is playable. He was noticeably braver here, rushing in to save Princess Peach, jumping on Bowser, and calling Count Bleck a goon. His special move is a jump that is so powerful it sent him out of the screen. He is the last character to join Mario's party.

Brainwashed by Count Bleck's assistant, Nastasia, Luigi became Mr. L, also known as The Green Thunder. Before Mario could get his hands on the fifth Pure Heart, Mr. L made his dramatic appearance in the Whoa Zone. Mario and his team didn't recognize that Mr. L was really Luigi. He attacked with a super jump and could use Shroom Shakes during battle. To stop him from using the Shroom Shake, the player could attack him before it heals him, or steal it for themself with Thoreau. When he was bested in combat, he revealed his trusted giant-robot "brother", Brobot, with which he attacked Mario in space. When he was defeated, he vowed to return. Later, at Count Bleck's lair, Mr. L did not seem to be pleased with Bleck's minions, going so far as to call them "junior" minions and calling them weak.

He returned as a boss in Chapter 6, after the Sammer Kingdom was destroyed. Here, he fought with Brobot L-Type. After being defeated, Dimentio betrayed him and sent him to The Underwhere. He lost all memory of his having been Mr. L and returned to his normal state. Mario found him scared in The Underwhere, and the two soon regrouped with the other playable characters (Bowser and Peach) as well.

Eventually, Luigi faced Dimentio in Castle Bleck alone, not even with a single Pixl by his side. He managed to defeat Dimentio, but gets knocked out by Dimentio's fake suicidal attack. Peach found and awakened him, and they and Bowser later rejoined Mario, and their combined strength allowed them to defeat Count Bleck. However, Dimentio then snatched the Chaos Heart, and activated a mind-controlling Floro Sprout he had planted on Luigi much earlier, turning his mind back into Mr. L. After explaining that the prophetic Dark Prognosticus stated that Luigi was the ideal host for the Chaos Heart, Dimentio and Luigi merged with the Chaos Heart, becoming Super Dimentio. The other three heroes managed to defeat Super Dimentio and turn Luigi back to normal, and they all witnessed Count Bleck and Tippi using their love to stop The Void.

Mr. L's name and attitude were likely taken from Mr. T, a wrestler. His personality and attire also seemed to be similar to the "gentleman thief" archetype of classic literature. The pose he did represented ballet, and was mostly opposite of O' Chunks' disco-like pose, even in its colors. Mr. L's other name, "The Green Thunder", may be a reference Luigi's Thunderhand ability in Mario & Luigi: Superstar Saga. Mr. L was also referenced in Paper Luigi's trophy in Super Smash Bros. Brawl, however, he was mentioned as "Mister L" instead (which is what he was called in Japan).

''Luigi's Mansion
During Luigi's Mansion, Luigi won a mansion in a contest he hadn't even entered. Luigi called Mario and asked him to visit the mansion. Mario got to the mansion first. When Luigi arrived, Mario was nowhere to be found and ghosts haunted the mansion. Luigi met Professor E. Gadd and received the Poltergust 3000, a vacuum that allowed him to capture ghosts.

Luigi went through the mansion, vacuuming many ghosts in order to save his helpless brother from the King of all Boos. In order to fill E. Gadd's gallery and find King Boo, Luigi had to capture twenty-three special ghosts. These ghosts were more powerful than regular ghosts, and each had a special ability unique to that ghost. After defeating all of the spooks, Luigi had to confront King Boo himself. Dressed in a Bowser Suit, King Boo had all the powers of Bowser and more. But nevertheless, Luigi prevailed and captured the King of all ghosts. After Luigi returned to E. Gadd's Lab, E. Gadd transformed them into paintings. Luigi saw that Mario had been turned into a painting as well. With the help of E. Gadd, he was freed from his pastel prison in a rather comedic way. After cleaning his mansion of the ghosts, Luigi was able to build a new and better version of his spooky mansion. After Mario was rescued, he went with Peach on another vacation, but this time without Luigi.

''Mario & Luigi: Superstar Saga
After Mario returned from his latest adventure, in Mario & Luigi: Superstar Saga, Luigi had to go on another adventure. When Cackletta stole Princess Peach's voice, Mario and Luigi had to go to the Beanbean Kingdom to get it back. Luigi wanted to stay in the Mushroom Kingdom, but after a series of tragic and hilarious events, he ended up going with Mario. Mario and Luigi used the Koopa Cruiser to get to the Beanbean Kingdom and save Princess Peach's voice from Cackletta and Fawful. Luigi sees how much help he is to Mario and decides to stay on the adventure, even though he was fearful the majority of the time. Luigi even has to dress as Peach for a while. Luigi also had to rescue Mario during the game when Mario got Bean Fever. He got hypnotized by Psycho Kamek into thinking he was Mario to get him more relaxed about going into the scary Guffawha Ruins. He went to the Ruins to get Crabbie Grass, the cure for Bean Fever (which might not make sense because if Luigi thinks he is the real Mario he will not understand that the true Mario is sick; however, it could be possible that he was merely trying to save the man who looked strikingly like him). On the way back to the Mushroom Embassy, in Little Fungitown, to deliver the grass, he got shocked by a lightning bolt and came back to his normal self. Luigi provides comic relief here, like in a few other games. For the first half of the game, most people recognize Mario, then called Luigi names like "Mr. Green Stache" or "Mr. Other Mario Bro". This was humor derived from Luigi always being in Mario's shadow.

''Mario & Luigi: Partners in Time
Once again, both Mario brothers unite in Mario & Luigi: Partners in Time. The princess had recently used E. Gadd's Time Machine to go back in time. She was trapped there by the Shroobs. Mario now had to go save her again and takes Luigi for some help.

Both brothers went back in time to find Peach. However when they went to the past, they were in the time period of the Shroob invasion. Later in the game, Mario and Luigi met their younger selves, Baby Mario and Baby Luigi, who helped them find the princess.

The brothers looked all over the past Mushroom Kingdom collecting Star Shards. The brothers ran into many different enemies, both new and old. They also ran into a few allies. Near the end of the brothers' journey, they traveled to Star Hill to find the remaining two pieces of the Cobalt Star. There, they met the Star Gate. Although passing Mario and the Babies worthy enough to travel through it, the Star Gate judged Luigi and said that he was not worthy enough to go in because of a dark secret in his past. After whispering to Luigi what that dark secret was, the Star Gate gave them three choices: go home and have a nice pasta dinner ending their quest, leave Luigi behind and continue without him, or finding the Aurora Block. The brothers searched through the entire Star Shrine and find the Aurora Block. Giving the block back to the Star Gate, the Gate asks Luigi who found the block, with only three answers (1. Mario, 2. The babies, or 3. Me, me, ME!) to choose from. Whichever answer he picked from, the Star Gate counted them all wrong and said there was a fourth answer, Everyone. Saddened, Luigi began to cry. Angry by the actions of the Star Gate, Mario and Baby Mario confronted the gate. After seeing them stand up for their brother the Gate labeled them the best siblings ever and allowed Luigi to pass. The Star Gate told the brothers that it was just a test and told Luigi to strike the Aurora Block with all of his new found might. The Star Gate told him that the block can grow by the size of the heart of the person who hits it. After saying that, the Aurora Block grows to gigantic proportions and flattened Luigi. With new found love for each other, the brothers continued on with their journey. After collecting enough shards, Mario, Luigi, Baby Mario, and Baby Luigi went to the past of Princess Peach's Castle, which has been turned into Shroob Castle.

Luigi and company defeated all the enemies, Princess Shroob, Elder Princess Shroob, and Shrowser. They finally saved Peach and went back to their own time. They watched sadly as Baby Mario and Baby Luigi traveled back to their time period.

''Mario & Luigi: Bowser's Inside Story
Yet again, Luigi joined Mario on an adventure in Mario & Luigi: Bowser's Inside Story. This time, the Bros. went to an emergency meeting in Princess Peach's Castle, warning about the dangerous disease plaguing the Mushroom Kingdom, called the Blorbs. Mario and Luigi arrived in the castle so hastily that Luigi was first shown hopping on one foot while trying to put on his overalls, causing him to trip and fall face-first on the floor, losing even a shoe. Later, for some odd reason, Luigi started feeling tired during the meeting and fell fast asleep without anyone noticing. He didn't wake up even when Bowser invaded the conference. However, Luigi did wake up when a mind-controlled Bowser came back to the castle and inhaled everyone there, including Luigi (due to Fawful's Vacuum Mushroom). Upon landing in the Trash Pit, Luigi must be rescued by Mario. Both of them, along with Starlow, must then find Princess Peach, and then a way out of Bowser's body. After they found Princess Peach, she told them of Fawful's plan of stealing the evil artifact known as the Dark Star. However, Fawful then took Peach away, and went to steal the Dark Star and re-awaken it using Peach's powers. The Mario Bros. then had to stop Fawful from using the Dark Star to bring darkness to the kingdom.

During most of the adventure, Luigi and Mario explored Bowser's insides and even helped him secretly because Bowser wanted to stop Fawful too. Fawful took control over his castle and was trying to conquer the kingdom Bowser wanted to. Though Bowser had no idea he had inhaled his sworn enemies, the Mario Bros. helped him in the backstages, with Starlow explaining to him what's going on with his body. She always used her false name Chippy to avoid being recognized while inside Bowser. The Mario Bros. could also use the Warp Pipes in the Pipe Yard to get out of Bowser's Body and go out on their own missions. Again, Luigi proved to be an invaluable help to Mario, often helping him throughout the adventure. At one point, Luigi even had to rescue Mario from a group of Sockops that had taken him. In order to do that, Luigi made use of a Sockop to traverse a field of thorns.

The unlikely trio eventually engaged the Dark Star in their final battle with the Dark Star itself already having used Bowser's DNA to turn into Dark Bowser. Bowser had to reduce Dark Bowser's HP to 0 so that the Dark Fawful Bug could fully revive him and make him bigger. Bowser then had to punch Dark Bowser's belly to have him spit out the Dark Fawful Bug and return to normal size. After that, Bowser inhaled the Dark Fawful Bug (while Dark Bowser tried to do the same) and (unknowingly) let the Mario Bros. fight it. In a battle similar to the one they had with Fawful's former mistress, they had to defeat the Dark Fawful Bug's body parts before being able to reach the Dark Star Core. Once they destroyed the Dark Fawful Bug, Dark Bowser became unstable. Then Bowser charged his punches to deliver the final blows on Dark Bowser until he exploded, freeing the kingdom forever from an age of darkness. The Mario Bros. then met up with a beaten Dark Fawful Bug. They were surprised to see that he survived. However, without a body or the Dark Star to sustain him, he didn't have much time left. With one last psychotic smile, Fawful explodes, hoping to destroy the Marios with it, however it instead released everyone from Bowser's body. Everyone then cheered on Mario and Luigi for saving the kingdom, but the celebration was cut short as Bowser was angry when he saw that Mario and Luigi were in his body, and engages the Marios and Starlow in what was to be another epic battle. As the credits rolled, the battle was shown.

''Dance Dance Revolution: Mario Mix
Luigi (or Mario, depending on who the player chose) danced to save the Mushroom Kingdom during the events of Dance Dance Revolution: Mario Mix. Waluigi went to Truffle Towers to steal the Music Keys and grant him the power to "hypnotize the rhythmless masses". However, after he opened the door, all but one key flew to various locations in the Mushroom Kingdom. One of the music Keys went down the sea, another one to Wario's Carnival and another one to Freeze Mountain. Toad, witnessing these events, rushed to tell Luigi. If all keys were not returned, they could fall into the wrong hands.

Luigi set out to find all four Music Keys, along with Toad. Using the S.S. Brass to navigate, Luigi challenged Waluigi (and other characters) to a "dance-off" and got all four Music Keys back.

After Luigi retrieved all the keys, Bowser accosted them. Bowser retreated into his castle and Luigi followed him on the S.S. Brass. Luigi won the "Final Dance Off" with him and got the Music Keys back. All the keys were subsequently returned to Truffle Tower.

''Mario Superstar Baseball
In Mario Superstar Baseball, Luigi was an alternative captain to Mario. His team names were the Luigi Gentlemen, Luigi Vacuums, Luigi Mansioneers, and Luigi Leapers. Luigi had similar stats and abilities to Mario in the series, but Luigi could perform a Super Jump on the field while Mario could not, and his Star Pitch was the Green Fireball.

''Mario Super Sluggers
In Mario Super Sluggers, Luigi's Mansion appears again as a stadium. Luigi appeared as a captain yet again and his team name was called the Luigi Knights. He also gained a new star pitch called the Tornado Ball to differentiate him from his brother. In challenge mode, Luigi was the first player that joined the team.

''Super Princess Peach
In Super Princess Peach, Bowser's minions, using the power of the Vibe Scepter, kidnapped Mario. They also kidnapped Luigi and Toad because they got in the way. Peach went on a quest to rescue them.

Bowser makes sure that he hid Luigi well because of what he had done in the past, which led him to hiding him late in the game.

Peach found Luigi in the boss level of Giddy Sky instead of a Toad. She defeated the boss, Giant Kamek, and rescued Luigi.

''Mario Smash Football
Luigi was a team captain in Mario Smash Football (also known as Super Mario Strikers in the U.S.). He was a Balanced player and his Super Ability was Super Luigi!. Luigi's number in Mario Smash Football is 2, probably referring to the fact that he was Mario's "second brother". In the game, his Super Strike was the Vicious Vortex.

''Mario Strikers Charged Football
Luigi returned as a team captain in the sequel to Mario Smash Football, Mario Strikers Charged Football (also known as Mario Strikers Charged in the U.S. version). He was a balanced player, and his Mega Strike uses electricity, most likely referring to his ability from Mario & Luigi: Superstar Saga: Thunderhand.

''Mario Hoops 3-on-3
Luigi appeared in the game Mario Hoops 3-on-3, as a playable character. Luigi is a balanced-type character. To use his Special Shot the player had to tap the "L" to shoot the amazing Green Fire Shot. Luigi's baller name was the Mushroom Dynamite.

''Itadaki Street DS
Luigi also appeared in Itadaki Street DS, where he joined many of his friends and Dragon Quest characters.

Mario & Sonic series
Luigi appeared in Mario & Sonic at the Olympic Games, as a playable character. Luigi's stats were balanced meaning he had no glaring weakness in any event. Luigi's emblem was his trademark green "L". Luigi also appeared in Mario & Sonic at the Olympic Winter Games. He's found in Frostown Plaza where he challenges Mario and Sonic to a Cross-Country race. If the player wins, Luigi will join the party. Luigi is later used in a mini-game in Sparkleton, where he had to grab a key from Boos by collecting batteries for a lamp, then finding the key inside one of the Boos.

''Mario Sports Mix
Luigi appeared in Mario Sports Mix, where he is classified as an all-rounder type character. His speed is average, while he has an above average technique. However, Luigi's power is below average.

Physical Description
Luigi is very similar to his older brother in appearance, although Luigi is slimmer and taller. His face is notably thinner and chinless. Luigi has a smoothed mustache and light blue eyes. He wears unfaded denim jean overalls, brown work shoes, and a green long-sleeve shirt. Luigi's Hat is similar to Mario's Cap, being green instead of red and having an "L" replace Mario's signature "M." Artwork for the Mario & Luigi series has consistently depicted Luigi as wearing red and white striped socks; this trait is not present in any other games.

Mario and Luigi's color preferences are reflected throughout the land in the form of various enemies, such as Koopa Troopas and Cheep-Cheeps, who also come in red and green varieties. These foes even reflect the brothers' personalities, with red ones being more aggressive and green ones acting cautious. In fact, Mario and Luigi are not the only known red and green brothers, with similarly color-coded siblings including Cork and Cask, Red and Green, the Armored Harriers, and Gigi and Merri. When tattling the younger of the Armored Harriers, Goombella theorizes that it may be some sort of rule that younger brothers must wear green, offering a possible explanation for Luigi's trademark green shirt and hat.

However, Luigi has not always chosen to wear his usual green and blue clothes. Mario Bros. originally dressed Luigi in a black shirt and green overalls, although artwork showed his shirt to be red. Wrecking Crew egregiously gave him a magenta pair of overalls and helmet, seemingly leaving him shirtless. Even Super Mario Bros. gave its Luigi a green shirt and white overalls (although Super Mario Bros. Deluxe replaced this with a less aberrant brown shirt and green overalls, leaving his original colors to Fire Luigi, who usually has an inverse scheme), despite the fact that his usual palette and appearance had emerged in artwork.

Luigi is rather infamous for being a palette swap of Mario in his earlier adventures. This applies to Mario Bros., Wrecking Crew, Super Mario Bros., Super Mario Bros. 3, Super Mario World, Super Mario World 2: Yoshi's Island, and even the rare solo quest that is Mario is Missing!. Luigi's first unique sprites came in Super Mario Bros. 2, in which his artwork appearance conveniently coincided with the tall Mama's sprite. Nintendo of Japan would not adapt Luigi's artwork differences to his in-game sprite until Super Mario Kart, although Luigi's various models have been unique almost ever since, even in remakes of games where he was originally a palette swap (such as Super Mario All-Stars, Super Mario All-Stars + Super Mario World, Super Mario Advance 2, and Super Mario Advance 4).

Both Mario and Luigi have been described as "cutesy," to the extent that Shigeru Miyamoto considered redesigning them to "become a bit more grown-up" in the GameCube era, for instance by removing their trademark V sign. However, aside from growing more realistic as graphics have advanced, Luigi and his brother have changed little over the years, and continue to flash the V sign regularly.

Luigi's appearance does, however, tend to lend itself to heavy stylization. The Luigi's Mansion graphical team took it upon themselves to animate every part of Luigi to convey emotion, resulting in such exaggerations to the plumber's body as head-expanding screams during boss cutscenes and complete flattenings by fake doors. The Super Smash Bros. series applies Luigi's cowardice to his actions, making most of his attacks look reckless and unwilling and giving him awkward movements, securing his official title as the series' "dreamy, comical poster boy."

Personality
Luigi is portrayed as timid and a bit of a coward. His cowardly attitude was first shown in Super Mario Adventures. He also worries and is considerably self-conscious. However, he overcomes his fears and acts like a hero when necessary. On the New Super Mario Bros. Wii website, it describes Luigi as "Mario's fearless brother". In keeping with his personality-based Power Flower, a sign in Big Boo's Haunt in Super Mario 64 DS describes Luigi as "wispy."

Arguably, Luigi's most apparent trait is his seeming cowardice. This was not seen until Luigi's Mansion (aside from a few hints in Paper Mario), but it has carried over to almost all of Luigi's subsequent appearances. Although Luigi's phasmophobia is his most overbearing fear, he usually reconsiders at the mere thought of any monsters or trials, especially in the Mario & Luigi series. However, Luigi can be quite brave, and has saved the Mushroom Kingdom alongside his brother multiple times. Super Paper Mario especially glimpses into Luigi's more courageous side, showing him boldly rushing into dangerous situations and rarely even implicating his cowardice.

Another strong element of Luigi's personality is his apparent complex over being overlooked. Although his Superstar status has earned him many fans, including an entire fan club led by Toadia and multiple supporting Toads (one of which claims to be his biggest fan in Super Mario 64 DS), even Bowser and the Koopa Troop have occasional trouble with remembering his name (as seen in Mario & Luigi: Superstar Saga), and he appears to be almost unknown in the Beanbean Kingdom. Although Luigi's biggest reactions to his frequent overlookings in the Mario & Luigi series are a few "..."s and face-faults, his inattention was played up for comic relief in Paper Mario, with the snarky man in green complaining about being left behind and perpetually training for that elusive next adventure. Luigi's bio in Mario Party 5 states that he has been gaining popularity in recent years.

Luigi's state of being in the shadow of his brother shows strongly in Super Smash Bros. Brawl. An example would be the way Luigi is almost never happy, how his commentary is very monotoned, and how one of his taunts is a bashful kick of the ground. Also, his Final Smash, Negative Zone, seemed to have developed because of living in his brother's shadow forever. Additionally, whenever the crowd cheers for Luigi, not too many people are heard cheering for him and when the announcer says Luigi's name, he sounds a little surprised. Despite this, however, Masahiro Sakurai did not intend to play up Luigi's overshadowed status, instead aiming to make him "everyone's favorite man in green."

When Luigi finally went on a quest of his own in Paper Mario: The Thousand-Year Door, he's presented as be more arrogant and somewhat of a liar, as he changes the stories of his adventure to make himself look better; his partners claim his stories are false. The novelizations of his escapades describe them with even more flowery exaggerations, stating for instance that he played an earth spirit in the Jazzafrazz Town Drama Slam (whereas he actually played grass on the side of the road, according to Hayzee) and that he awoke Cranberry with "a soft call" (rather than a sneeze).

In Mario & Luigi: Partners in Time, the Star Gate (which supposedly knows all) passes Luigi as "unworthy" to enter. This most likely has something to do with Luigi's "dark secret from his past," which it also mentions; Luigi did something either embarrassing or foolish which he has kept a secret ever since. However, in a interview with a member of staff, he stated Luigi had no dark secret, and it was actually a reference to the fact Luigi constantly lives in the shadow of his brother. He also added: "Why make Luigi into a bad guy? We have Waluigi for that instead!" Even the game itself makes a straightforward point that Luigi has a large heart, as proven when he hits the Aurora Block and it grows to a gigantic size, flattening him.

Luigi is also portrayed as somewhat refined, leading the "Luigi Gentlemen" in Mario Superstar Baseball. Luigi's Mansion shows him to be a bit of a neat freak, constantly criticizing the dustiness of his mansion and even mentioning at one point that he hand washes his cap as opposed to using a washing machine as his brother does. He also seems to have an eye for art, but doesn't appreciate many of King Boo's decorations. Like Toadette, Luigi can be sensitive when someone insults him, especially if the jab in question regards his mustache (as proven prior to his showdown with Dimentio). Luigi also appears to show concern for cruelty to animals; he is horrified by the deer heads and leopard skin rugs in the Safari Room in Luigi's Mansion and declares that he won't stand for an animal being treated in such a manner.

Whereas Mario rarely speaks aside from numerous yells and grunts (a point is made out of this in Super Mario RPG: Legend of the Seven Stars with Toad and The Thousand-Year Door with Doopliss), Luigi is proven to be quite the conversationalist in the Paper Mario series. In Super Paper Mario, Luigi is almost Mario's "mouth." He does all the speaking for Mario in the beginning of the game (a role later taken by Tippi). Once he joins Mario's party, however, he only talks during scenes where the four heroes are shown together. Curiously, the inverse seems to be the case in the rare instance of a Luigi-only quest; both brothers are capable of captioned speech in Luigi's Mansion, but Luigi is limited to ellipses and question marks when interacting with another character. In the Mario & Luigi series, Luigi, as well as Mario, talks in gibberish that the player can't interpret, but the other characters in the game do.

In The Super Mario Bros. Super Show! Luigi is consistently portrayed as being the smarter of the two, but the cowardice trait is also shown as Luigi is scared of things going very wrong. He also doesn't take as many risks as Mario does.

Overall, Luigi's personality is hard to determine and tends to change depending on the appearance. Very few games have portrayed him with a personality that lasts throughout the subsequent release. Overall, however, Luigi can be described as timid and cautious, yet kindhearted and willing to protect his homeland with Mario's help - It is perhaps this irony, the basis of Luigi's character, that makes his personality so complex.

Luigi's Age
Originally, Luigi was introduced as Mario's younger brother. The first indication of their specific age difference was in "Family Album "The Early Years"", which implied that Luigi was born after Mario by several years. However, Super Mario World 2: Yoshi's Island and Yoshi Touch & Go described the brothers as twins. The remake of the game, Yoshi's Island: Super Mario Advance 3, did not expressly call them twins, but noted that Luigi was Mario's younger brother, carried to their parents at the same time. However, many video game sources still refer to Luigi as the younger brother, indicating that Luigi may have been the second born twin, regardless of his delivery by the Stork. Since Luigi is still said to be Mario's younger twin brother it can be assumed that he was born right after Mario, making them just about the same age. In Super Paper Mario, Luvbi refers to Mario and Luigi as twins at the end of chapter 7-1. It should be noted that in the same game, though, Luigi referred to Mario as "big bro" on more than one occasion. Also, Luigi's Trophy description in Super Smash Bros. Brawl also referred to him as "younger twin brother". However, Colonel Roy Campbell calls Luigi a "kid brother" to Snake during Snake's Codec conversation in the same game. The 1993 film depicts Luigi in his early 20s, while Mario is in his mid-40s.

Abilities
As to not give players advantages over each other, Luigi's abilities are usually exactly the same as Mario's, such as in Mario Bros., Super Mario Bros., and Super Mario World. In most instances where one player can choose between the two brothers, however, Luigi is given his own gameplay quirks. This first occurred in Super Mario Bros.: The Lost Levels, where Luigi can jump higher than Mario but has lower traction and speed. In the American Super Mario Bros. 2, Luigi once again features the highest jump, but comparatively low speed and power. Luigi's high jumps but low traction would return in Super Mario Advance 2: Super Mario World, which, unlike its original version, allowed players to switch between Mario and Luigi at any time on the map screen. In three-dimensional adventures, such as Super Mario 64 DS and Super Mario Galaxy, Luigi is usually faster than Mario (at the cost of poorer acceleration), but retains his classic high jumps and poor traction.

As aforementioned, Luigi has a higher top speed but poorer acceleration than his brother in Super Mario 64 DS, along with poor traction and increased agility. In this game Luigi along with Yoshi are the fastest swimmers. Luigi's jumps are perhaps at their strongest in this game; not only can Luigi jump higher than his brother, but he can also scuttle to slow his fall. His backflip has the same effect as being caught in a Tweester or stomping a Fire Guy, allowing for a very slow descent. Unlike Mario, however, Luigi cannot Wall Jump in this game. As a result of his agility and lightness, Luigi can walk on water for a short time. Luigi's Power Flower is Vanish Luigi, allowing him to disappear for invincibility and the ability to walk through certain obstacles.

In Super Paper Mario, Luigi's specialty is the Spring Jump, which sends him just off the screen to bound over obstacles and damage enemies mid-air. His standard jumps are also higher than any other character's and he has lower traction once more.

Electricity is sometimes depicted as Luigi's answer to Mario's fire. In Mario & Luigi: Superstar Saga, Luigi is given the ability to harness and release electricity with a technique known as the Thunderhand (alongside his other specialty, the High Jump). This is referenced in Super Paper Mario with Mr. L's nickname of "The Green Thunder," and in Mario Strikers Charged Football, where Luigi's Mega Strike involves controlling electricity.

In addition to actual gameplay differences, Luigi often executes his moves differently than his brother. In Super Mario All-Stars + Super Mario World, Luigi jumps with his legs back and descends with them forward, kneels when sliding, and, interestingly enough, appears to spit fireballs rather than throwing them. The Super Smash Bros. series and Mario Kart: Double Dash!! give Luigi green fireballs, and in the former games his fireballs levitate. Perhaps most famously, Luigi's jumping animation in Super Mario Bros. 2 is merely his walking animation sped up; although Luigi's "kicking" jumps were momentarily ignored, they returned in the Super Mario Advance series, complete with a high-pitched warbling sound effect in Super Mario Advance 2 and 4. Luigi's aforementioned scuttle from Super Mario 64 DS also involves walking in mid-air, and the Eternal Understudy "kicks" during his Triple Jump in Super Mario Galaxy.

Luigi has also exhibited many unique traits in various sports and spin-off games, despite usually being a balance character like his brother. In games such as Mario Kart Wii, Luigi has a higher top speed than Mario, but has lower handling and acceleration. In the Mario Golf series, Luigi his with less power than his brother but features better control, although his shots consistently curve left. Luigi is slightly faster than Mario in Mario Superstar Baseball, and reveals his special pitch and swing (the Tornado Ball and Tornado Swing, respectively) in Mario Super Sluggers.

Despite his skills, Luigi is also somewhat clumsy. For example, in Paper Mario: The Thousand-Year Door, he accidentally bumps one of his partners, Blooey the Blooper, into a volcano while trying to stop evil, burning him to a golden crisp but not killing him. Usually, though, he is very agile and can do many stunts Mario can not, and in fact appears to be the best jumper in the Mushroom Kingdom.

Roles Taken
Luigi is a hero, but usually a sidekick, although in some media and games he is referred to as a partner. In the Mario & Luigi games, he is the cowardly partner to Mario, and is occasionally forced to be brave. He is the hero of a separate adventure the player doesn't get to play or see in Paper Mario: The Thousand-Year Door, where he is a coward who changes the story to make himself look more heroic. In Super Paper Mario he was not a sidekick, but rather one of the four heroes, which made him equal to Mario. He was also brainwashed by Nastasia to become a villain, Mr. L, and was later brainwashed again by Dimentio to become Super Dimentio, the final boss. His sidekick role was completely different in Mario is Missing! and Luigi's Mansion, where he was the sole main character who had to rescue Mario.

Nicknames
Since Mario has starred in many more games and has been on many more adventures than Luigi, he has received most of the popularity. Almost everyone knew who Mario was. Luigi, on the other hand, has smaller popularity compared to Mario's and is unknown to most. Luigi's nicknames usually have to do with the color of his clothing.

Bowser
Bowser is Luigi's first enemy. Luigi and Bowser have almost always been enemies, but Bowser's main rivalry is with Mario. It may be worthy of note that, in Super Paper Mario, Luigi was seemingly unaware of Bowser's almost clichéd past attempts, stalling to realize that Bowser was the sort of person who would kidnap Princess Peach, and even then not remembering Bowser's name until he actually encountered the Koopa King. Similarly, Bowser does not recognize Luigi when they meet in Mario & Luigi: Superstar Saga, although he does remember who he is in Super Paper Mario. Worth noting is that Bowser seems to recognize Luigi as being almost as great a threat as Mario and remembers his name in Super Mario Galaxy and Super Mario Galaxy 2. Luigi has always been one of the three main heroes Bowser hates with a passion, with Mario and Yoshi being the other two.

King Boo
King Boo was the main boss of Luigi's Mansion, starting a bitter rivalry. The two of them don't seem to work together very well, two examples being the bad chemistry between the two in Mario Baseball and the fact that Luigi claimed King Boo's old crown in Luigi's Mansion. In Super Mario 64 DS, Luigi was locked up by King Boo. While not as extreme, Luigi's negative relationship with King Boo could be a reflectant of Mario and Bowser's lengthy rivalry. Though, oddly, King Boo has shown he can act somewhat civilly to Luigi, and makes small talk before blowing him back to the Foyer in Luigi's Mansion if Luigi shows up at the Secret Altar door before he has enough Boos.

Mario
Mario is Luigi's older twin brother. Luigi often joins Mario in missions to save Peach, but Mario tends to go on adventures without him. Despite their lifelong sibling rivalry and Luigi's jealousy toward Mario, Mario and Luigi have always maintained a unique "brotherly love" for each other which is further proven when Luigi rescues his brother in Mario is Missing! and Luigi's Mansion. Baby Mario himself aided Yoshi in Luigi's rescue in Super Mario World 2: Yoshi's Island and Yoshi's Island DS. Luigi also has a great admiration for his older brother and looks up to him, wishing to be "a great plumber like his brother Mario" in Super Mario RPG. Mario and Luigi are automatic partners in most games.

Princess Daisy
Daisy's only appearances between Super Mario Land and Mario Tennis was in NES Open Tournament Golf, where she caddied for Luigi just as Peach did for Mario; this would be Luigi's first documented interaction with Daisy. In Mario Tennis (Nintendo 64), when choosing Luigi in the doubles tournament mode, his default partner will be Daisy. Luigi and Daisy have been portrayed as a couple on numerous occasions. In Mario Golf Toadstool Tour, they're seen golfing alongside Peach and Mario. Their team names from the Mario Party series include: "Steady Sweeties", "Tango Tanglers", and "Shy Sidekicks". Perhaps the most telling occurrence was in Mario Power Tennis, wherein Daisy says to Luigi, "Hey, sweety! I'll take that", while receiving her trophy from Luigi. Also, in the Mario Baseball series, Luigi and Daisy are "buddy players", and they share good chemistry. Most recently, in Mario Kart Wii, there is a giant, golden statue on the Daisy Circuit that shows the two holding hands and dancing together, along with another of Baby Luigi and Baby Daisy. Arguably the greatest evidence for any existing relationship between Luigi and Daisy is in the Super Mario Bros. film, released in 1993. Luigi and Daisy were quite clearly depicted as being infatuated with one another in this movie. Nintendo's only official word on this matter came in Super Smash Bros. Melee, where Daisy's trophy biography states, "After her appearance in Mario Golf, some gossips started portraying her as Luigi's answer to Mario's Peach".

It was stated in the official Mario Party 4 guide that Luigi has quite the crush on Daisy, and that it's rumored there's an attraction between them. Luigi and Daisy also appear together commonly in the Miracle Book pages from Mario Party 6. Most often in a situation where something bad happens to Luigi, but Daisy is left unharmed. Examples of this include the page Amp Attack, where Luigi and Daisy are playing Circuit Maximus, and are wondering what the three black spheres are. The player can press to make them turn around, which reveals that the spheres are Amps which then electrocute Luigi. On another page titled It Came from the Deep, Daisy and Luigi are fishing for treasure in Treasure Trawlers. If the player presses Daisy gets a treasure chest while Luigi catches the tentacle of a Blooper.

Princess Peach
Princess Peach is portrayed to be Luigi's very close friend. In any game where Luigi can switch Mario for the same role, Peach reacts to him in the same manner she does to Mario, like in New Super Mario Bros., where Peach will give Luigi a kiss after he saves her. Similarly, Super Mario Galaxy 's identical storyline for both Bros. has Rosalina referring to Peach as both Mario and Luigi's special one. Luigi is seen swooning over Peach after she blows a kiss in her Mario Power Tennis victory scene. They were both together in Mario Power Tennis in Diddy Kong's and Koopa's endings. In Super Paper Mario, Luigi comes to Peach's rescue in an attempt to stop Count Bleck and the wedding between Peach and Bowser, focusing on Peach rather than attempting to save Mario. The two share chemistry in Mario Superstar Baseball, and are called Green Eschort in Mario Party 5. In Super Mario Galaxy after finish the story line with Mario and play as Luigi. At the end of the game Peach and Luigi fly away holding hands, the same with Mario.

Rosalina
Rosalina met Luigi in Super Mario Galaxy. Luigi helped her by aiding Mario in retrieving the Power Stars. In Battlerock Galaxy, he tells Mario that he'll only give him the Green Star if he tells Rosalina that he found it for her. Strangely, Mario never does tell Rosalina that Luigi found it. Upon collecting all 121 stars with both Mario and Luigi, Mailtoad sends a picture when the player talks to him in the Grand Finale Galaxy. Luigi's picture shows him, Rosalina, and the Toad Brigade with Peach's Castle in the background, while Mario's picture is of Mario, Peach, and three Lumas on the first planet of Good Egg Galaxy.

Starlow
Starlow is a friend of Luigi and Mario, but she generally interacts with Mario more so than with Luigi. Starlow also acts more coldheartedly toward Luigi, as in one humorous scene, before the battle with Alpha Kretin, Luigi asks Starlow to fight alongside Mario instead, and she responds by angrily knocking him into the beast, or even after (optionally) finding and defeating the three frozen Shroobs, in which she comments that only Mario could have been able to defeat the Shroobs as a baby. Mario responds that Luigi also helped, and Starlow, dubious about it, says that Luigi possibly attacked them with some "ferocious crying". This, of course, made Luigi sad, and Mario says to Starlow that Luigi was the one who defeated the Shroobs in the end. Starlow, impressed about Luigi's potential, then apologized to him, saying that he is indeed super like his brother, thus making Luigi happy again.

Toad
Toad directly adventured with the brothers in Super Mario Bros. 2. Besides giving Luigi tips and the occasional pick-me-up, Toad doesn't spend nearly as much time with Luigi as he does with Mario. The various Toads' opinions of Luigi in Super Mario 64 DS greatly differ from one another, with one denying that he could have retrieved so many Power Stars and another referring to Luigi as "The world's most inept and least charismatic brother," while another refers to himself as Luigi's biggest fan and another states that "We'll have to call you the Luigi Brothers soon!". Toad also acted as Luigi's major ally in Luigi's Mansion, giving special items (such as keys) and allowing the player to save their game. In the Mario cartoons, Toad appears as both a helper and a close friend of Mario and Luigi. Toad has been on good terms with Luigi for a very long time.

Waluigi
Waluigi seems to nurture an especially hostile grudge against Luigi due to unknown reasons. In Mario Tennis, it is revealed that the two have shared some sort of rivalry, also Luigi makes a gesture at Waluigi which Waluigi reacted negatively to. It is stated in the Mario Party 4 guide that Luigi has a crush on Daisy and so does Waluigi. This might be a reason that the two share rivalry. In all, they have bad chemistry in all the games they appear in together. Their relationship is similar to Mario and Wario's.

Wario
Wario was saved from Chief Chilly by Luigi in Super Mario 64 DS. In the past, Baby Wario saved Baby Luigi from Kamek along with Yoshi and other characters in Yoshi's Island DS. Wario seems to have a competitive rivalry with Luigi, as shown when they argue over whether being a superstar requires brains or brawn in the Mario Party introduction. Wario also enjoys tying Luigi's shoelaces together. Nintendo Power has stated that Wario is the cousin of Mario and Luigi, but this hasn't been confirmed yet.

Yoshi
Yoshi is one of Luigi's closest friends. Luigi and Yoshi are often seen going on adventures together alongside Mario, playing the roles as the second or third playable characters. In most spin-off games, Luigi and Yoshi are commonly referred to as 'The Green Team' if they are both partnered up together. Luigi and Yoshi could be considered to be just as good friends to each other as they are to Mario, as they both show connections to each other like true friends would. Oddly, however, in Mario Superstar Baseball and Mario Super Sluggers, their chemistry is neutral.

According to the Super Mario World TV Show's episode, Mama Luigi: Luigi found Yoshi, and at first, Yoshi thought that Luigi was his "mama." And it seems that Yoshi likes Luigi more than Mario, due to the fact that Luigi brings Yoshi to bed, and Yoshi asked him to tell a bedtime story.

Design
Since his debut in 1983, Luigi has been constantly developing. Gameplay differences between him and Mario were first seen in Super Mario Bros.: The Lost Levels. After spending years as an edit of his brother, Luigi had consistently his own graphics since Super Mario Kart in 1992, with earlier exceptions including the American Super Mario Bros. 2. As aforementioned, Luigi had begun earning his own personality in the post-Super Mario 64 era, starting with Paper Mario and Luigi's Mansion.

Online Collectible Card Bio
''With his trusty Tornado Ball and signature green cap, Luigi is the talented team captain of the Luigi Knights. He may not have as much confidence as his superstar brother Mario, but not everyone can be a hero, right?''

Bio
''Luigi is Mario's brother and the family resemblance is obvious. Like Mario, Luigi is an All-Around type of guy, not excelling in any one area but showing solid ability in many events in the Olympic Games.''

Bio
''Luigi is the taller and younger twin brother of Mario. He has been on many adventures with Mario and now comes to Vancouver to compete in the ultimate winter competition. Using the Luigi Rocket technique on the Wii and DS or Green Fire Dash on the DS, he brings a unique advantage that he hopes will propel him to the top.''

Super Smash Bros. Profile
''Though often hidden in his older brother Mario's shadow, Luigi is, in reality, very popular. Taller than Mario, Luigi also jumps higher. Although he didn't appear in Super Mario 64, in Mario Kart 64 he performed to the best of his ability. For one who seems to always be in the background, he has many fans who eagerly await his appearance.''

Bio from The Adventures of Super Mario Bros. 3 Writers Bible
''Mario couldn't have a better teammate than his younger in age, but bigger in size, little brother Luigi, even though they approach their adventures with very different attitudes. Luigi always wishes Mario would take more time to weigh the risks before he leaps, swims, or flies into the unknown. But no matter how much he questions Mario's plans, Luigi always loyally follows him into the wildest dangers any Koopa could conceive. Luigi is your basic soft touch. A defender of downtrodden Mushrooms and Koopa-nabbed maidens. Naive, trusting and innocent, Luigi is not a bumbling fool. It's just that he's so nice and straightforward, which allows him to be sucked into a Koopa scheme, a Toad prank, or a Mario madcap plan.

Mario Kart Wii Trading Card Description
