Waluigi

"Hey! You might be getting better, but nobody cheats better than Waluigi! You got that?!"

- Waluigi

Waluigi is Luigi's lanky rival and Wario's partner. Waluigi made his debut in Mario Tennis, and since then, he has made playable appearances exclusively in the Mario franchise's spin-off titles. He makes an appearance as a playable character in all but one game in the Mario Tennis series. He has been voiced by Charles Martinet ever since his debut. His name is a portmanteau of the Japanese words warui, meaning "bad", and Ruīji, meaning "Luigi".

Creation and development
During the development of Mario Tennis, the game had many classic Mario characters, but few were humans, and Wario did not have a partner for doubles. Then, designer Fumihide Aoki came up with the idea to make a rival for Luigi. Shigeru Miyamoto was consulted in order to help with the design. Between the development cast, names like "Jeroji", "Jinani", and "Waigi" popped up, until it was decided that the name would be "Waruiji", portmanteau of the words "Warui" and "Ruiji". It was also decided that the character would be the extreme to Luigi's height and lean body, just as Wario was the extreme to Mario's round and short body. According to Shugo Takahashi, Yoichi Kotabe put on the finishing touches for Waluigi's final design.

During Waluigi's development, there were propositions of creating a "Warupichi", which means "Wapeach" and possibly a "Warui" version of Princess Daisy, but these ideas were dismissed by Shigeru Miyamoto.

A September 2000 English edition of Nintendo Power introduces Waluigi and the fake online game Waluigi's Toenail Clipping Party:

 He's lean, he's mean, he hates the color green! Yes, with hopes of finally overthrowing Mario's supreme reign as the video game king, Wario has enlisted the help of Waluigi. The big fellow with a nasty smirk and burning hatred of good, ol' Luigi finally shows his ugly mug in Mario Tennis, and to mark the momentous occasion we're giving the purple one his very own website! You can check out www.waluigi.com for all your evil sidekick needs: photos, secret information, and all the wacky hijinks you could ever desire. Were looking to have online games, too, including Waluigi's Toenail Clipping Party. It seems that everyone's favorite mustachioed mischief maker has let his personal grooming go, and it's up to you to help him. Clip those nails good, and be sure to aim for the jar, or you'll be left with ragged clippings and toe jam all over your hard drive. Eewwww! 

The section also claims: "He's so bad, he sold Luigi's underwear on EBay. Which raises an interesting question… who bought the stuff?" In 2020, a photoshop of this section of Nintendo power claiming Waluigi's real name was Jimmy Poppadopolos went viral on Twitter.

Mario Tennis
Waluigi makes his debut in Mario Tennis for the Nintendo 64. In the opening of Mario Tennis, several characters are introduced as participants in a tennis tournament. Wario and Waluigi watching from afar while lurking on the sidelines of the court. The two then appear in front of the trophy to interrupt the final match between Mario and Luigi. Waluigi states that they want to play, but Luigi declines and mocks Waluigi, which upsets him. Waluigi and Luigi prepare to fight as they walk up to each other. Mario tries to stop them, but Wario stands in his way. Suddenly, Bowser falls from the sky alongside a Boo, knocking Wario and Waluigi onto the ground. Everyone becomes worried at first, but Bowser and the Boo reveal that they just want to play tennis too. Mario allows the villains to play, and everyone cheers. A Bob-omb then appears and explodes inside the stadium.

Waluigi is a Technique character in Mario Tennis, which means Waluigi has good control over the ball. Also, he has above-average reach. Waluigi lacks power and movement speed, however.

Waluigi also appears in the Game Boy Color version of the game, where he is an unlockable Technique character. He can be unlocked only if a Transfer Pak is used. Due to this, he is not playable in the Nintendo 3DS Virtual Console release of the game. In the Two-on-One minigame, the player as Bowser plays against Wario and Waluigi. Waluigi is also playable in his own minigame, playing against Luigi.

Mario Power Tennis
Waluigi reappears in Mario Power Tennis as a playable character. When the game starts, he is seen holding a Camelot sign.

In the intro movie in Mario Power Tennis, Wario and Waluigi face the Mario Bros. in the first round of a tennis tournament. Mario and Luigi defeat them.

Some time after the match, Wario and Waluigi head to Peach Dome, where they notice the tournament board which shows that they have been eliminated. They decide to vandalize the picture of the Mario Bros. on the board in revenge. However, a group of police sees them in the act and attempts to arrest them. Wario and Waluigi run from the police for a while before hiding in a side room, which turns out to be an entrance to Bowser's workout room. The three then form an alliance, and Bowser has Wario and Waluigi train there while the tournament continues.

They interrupt the final match of the tournament; the Mario Bros. against Yoshi and Donkey Kong, turning it into a rematch. They are booed, and decide to fire Bob-ombs at the Mario Bros.. Bowser helps them in a giant balloon full of Bob-ombs. However, the Bros. and the other characters hit the Bob-ombs back at Wario and Waluigi with their tennis rackets, blowing up parts of the Peach Dome. Bowser fires a Bullet Bill at Mario, but he deflects it with his tennis racket, sending it into Wario and Waluigi's Bob-omb launcher, which malfunctions and fires a Bob-omb at Bowser's balloon. Since the balloon was full of Bob-ombs, it crashes into the ground near Wario and Waluigi, causing a huge explosion. The three faint as a result.

In Mario Power Tennis, Waluigi is a Defense character. He has great reach, but his movement and power are somewhat limited. Waluigi is one of the two Defense characters in the game, the other being Wiggler. The game is the first to feature Waluigi's ability to swim through the air, a move that has recurred in other games. Waluigi's Offensive Power shot is the Whirluigi, a backspin shot that gives returners a whirlwind affect, losing the returner's control. Waluigi's Defensive Power Shot is the Swimming Return. Here, a pool appears in the court, and Waluigi swims to hit the ball.

Mario Tennis: Power Tour
Waluigi also appears in Mario Tennis: Power Tour, with the same traits as in the game's GameCube counterpart. This is the only Mario game thus far, excluding the online tournament demo for Mario Tennis Aces, where Waluigi appears as a playable character but his partner, Wario, does not (although the latter can still be heard at the beginning of the game's intro shouting "Nintendo"). Waluigi has the same offensive and Defensive Power Shot that he had in Mario Power Tennis.

Mario Tennis Open
Waluigi returns as a playable character in Mario Tennis Open, as one of the game's two defense type characters (the other being Dry Bowser). Waluigi is relatively unchanged, but his winning animation depicts him with flashing eyes, a reference to Waluigi's reaction to winning a point in the Nintendo 64 version of Mario Tennis.

Mario Tennis: Ultra Smash
Waluigi returns as a playable character in Mario Tennis: Ultra Smash. Like Mario Tennis Open, he and Dry Bowser are the only two defense type characters in the game.

Mario Tennis Aces
Waluigi returns as a playable character in Mario Tennis Aces, in which he is once again a defensive character and wears a new tennis outfit. He also appeared as an unlockable playable character in the game's online tournament demo, unlocked after 100 points were accumulated. Waluigi's Special Shot is "Showtime", where he inserts a rose between his teeth, does several pirouettes, and hits the ball. Waluigi's side Trick Shot is "Moonwalk", and his forwards and backwards Trick Shot is "Twisted Jump" involving him jumping in from of the ball. By earning 1000 participation points in the July 2019 or January 2020 online tournaments, the player could unlock a costume of Waluigi with his normal overalls.

Waluigi plays a major role in the game's Adventure Mode, where he and Wario steal Lucien, after hearing of the racket's legendary power. In the intro cutscene, where Wario and Waluigi are seen digging in the Bask Ruins. They uncover a golden chest, containing Lucien. Wario and Waluigi fight over the racket, and start getting shocked by it. Later, after Mario and Peach win a tennis match, they enter the Marina Stadium. Wario and Waluigi decide to give Lucien to Mario as a present, but Luigi grabs it first and a dark storm cloud appears, and Lucien possesses Luigi, Wario, and Waluigi. Waluigi later appears as an Adventure Mode opponent who challenges Mario and Toad to a tennis match. After the duo succeeds, Waluigi is transformed back into his standard form. Later on, Bowser combines himself with Lucien to create Bowcien, a "dark", superpowered version of the Koopa King. When Bowcien is finally defeated, Wario and Waluigi both express disappointment that they could not use Lucien to become "the best tennis players in the world". Daisy scolds the duo for stealing Lucien and causing this problem in the first place.

Mario Party series
Waluigi makes an appearance as a playable character in every game in the Mario Party series since the third installment, except for Mario Party Advance. In Mario Party 3, he is not playable in story mode, but he has been fully playable from the beginning in all other games that he appears in.

Waluigi's only major appearance that does not simply include him as a playable character is in his second appearance, Mario Party 3. After clearing the penultimate board, Mario and his friends are ambushed by Bowser, who announces that the protagonists have to fight him for the Mischief Star Stamp. Tumble then realizes the Star Stamp is missing and Waluigi reveals that he has stolen it. Bowser attacks Waluigi for the stamp, but is defeated. Waluigi then challenges the other party members to a duel on his own board, Waluigi's Island. However, once Waluigi is defeated, he forfeits the Star Stamp. He is the only playable character in the game to have a board named after them.

Waluigi appears in a few minigames in Mario Party-e. In Waluigi's Reign, Waluigi drops hammers, coins, and red coins on Mario. In Time Bomb Ticks!, Waluigi hits buttons in order as quickly as possible to give Mario less time to stop the bomb. Waluigi also appears in two cards, Waluigi and Super Waluigi. They are both duel cards, which involves dueling a player for coin cards and in-play cards, but Super Waluigi costs coin cards.

In Mario Party 5, Mario Party 6, Mario Party 8 and Mario Party DS, Waluigi has team names for different combinations of characters. These team names are as follows:

In Mario Party 7, Waluigi shares a character-specific orb with Wario: the Vacuum Orb. By using a roulette, Waluigi can steal other opponents' coins.

In Mario Party 8, Waluigi flaunts a rose for his winning animation. Waluigi's holding a rose is a recurring trait for him in various later appearances including Mario Golf: World Tour, Mario Tennis Aces, Mario Party Superstars, and even as art during Nintendo Minute's Nintendo Switch Lite Blue unboxing video.

In Super Mario Party, Waluigi's Dice Block has one -3 coins, one 1, one 3, two 5's, and one 7. His Dice Block is colored purple.

Super Smash Bros. series
Waluigi makes his first appearance in the Super Smash Bros. series in Super Smash Bros. Melee, where he appears as a trophy, number 207, via the Lottery after collecting at least 250 other trophies. His description states that he spend a large quantity of time training for Mario Tennis, "honing" the ability to annoy Mario and Luigi. The description also notes that he is the same age as Luigi, and that the status of his relationship with Wario is unknown.

Waluigi later appears as a Sticker, trophy, and an Assist Trophy in Super Smash Bros. Brawl. His two Stickers are of his appearances in Mario Superstar Baseball and Super Mario Strikers. Both Stickers can be used by Bowser, Peach, Yoshi, Mario, and Luigi, and both increase attack; the former increases the user's long-ranged special attack by eight, and the latter increases the user's strength of moves which use claws or blades by fifteen. His trophy appearance, with includes his tennis racket, again has a description which notes that his relationship with Wario is unknown, and that he worked "silently in the shadow of the Mario Bros." before he could compete against them in Mario Tennis. For his Assist Trophy, he appears with a tennis racket in hand, which is a reference to his debut in Mario Tennis. He kicks his chosen opponent into the ground and finishes up by delivering one final kick or a blow with his tennis racket. Also, one of Luigi's alternate costumes resembles Waluigi's outfit.

Waluigi appears as an Assist Trophy again in Super Smash Bros. for Nintendo 3DS / Wii U. Additionally, Luigi regains his Waluigi-inspired alternate costume (albeit with a purple L instead of yellow) while Mario gains the same costume, the only difference being that his M is yellow like Waluigi's Γ.

Waluigi returns in Super Smash Bros. Ultimate as an Assist Trophy. Also, Mario and Luigi retain their Waluigi-inspired alternate costumes. Two spirits of Waluigi appear, one of which uses artwork of his regular appearance, the other using his artwork from Mario Strikers Charged. He also appears in the Standard Bike's spirit. His regular appearance fight has Waluigi appearing as an Assist Trophy enemy, and takes place on Peach's Castle. His Spirit fight for his Mario Strikes Charged appearance has the Soccer Ball item rule and takes place on Wuhu Island. Both fights are against Luigi, referencing his rivalry with him.

Game & Watch Gallery series
Waluigi only appears in one game in the Game & Watch Gallery series, Game & Watch Gallery 4; he appears in the games Boxing and Rain Shower. In Boxing, Waluigi appears as Luigi's final opponent, where he attacks by elbowing and kicking in contrast to Luigi's punches. Waluigi is controlled by the second player in Link Cable multiplayer.

In Rain Shower, he appears only on Hard Mode, where he moves the lines around, putting the other characters (including Wario) in danger of Bowser's water balloons.

Mario Golf: Toadstool Tour
Waluigi also appears in the game Mario Golf: Toadstool Tour. He is also an unlockable character in Mario Golf: Advance Tour. He can be unlocked only via transfer between the Nintendo GameCube and Game Boy Advance games.

In Mario Golf: Toadstool Tour, Wario and Waluigi see the Mario Bros. golfing with Princess Peach and Princess Daisy. They challenge Yoshi and a Koopa Troopa to a game of golf. However, Wario ends up flinging sand from a sand trap into Waluigi's face, and Waluigi cannot putt his ball into the hole, which causes their opponents to fall asleep. The duo then challenges Donkey Kong and Diddy Kong.

During this game, Wario hits his ball hard, making it fly into the forest across the hole. Wario and Waluigi celebrate until they hear a loud roar. The two look up and see Bowser in his Koopa Clown Car, and he has a black eye from Wario's golf ball. Bowser starts firing Bullet Bills at the two until they escape via a yellow Warp Pipe that is too small for the Koopa Clown Car to fit through. Wario and Waluigi come out the other side of the pipe and stop to catch their breath, but Bowser catches up to them and prepares to throw a Bob-omb at them.

Wario and Waluigi try to escape from Bowser by going through an enormous metal door. Meanwhile, Mario hits his ball with his golf club just as Waluigi is able to open the door. At that moment Mario's ball bounces off Wario and Waluigi, giving them black eyes too, and knocks the Bob-omb off Bowser's hand. The Bob-omb explodes on Wario, Waluigi, and Bowser.

Waluigi is a default playable character in Mario Golf: Toadstool Tour. His shot path is to the right while he can hit the maximum at 209 yards. He has slightly above average impact and spin with relatively average control. His shot height is medium.

For his eagle animation, Waluigi jumps, makes several poses, and pirouettes. He makes the poses without pirouetting for his birdie animation, for his par he points his hands forwards, for his bogey he has a look of disappointment, and for his double bogey animation he holds his fist to his chest, makes exaggerated screeches, and falls onto the ground.

Mario Golf: World Tour
Waluigi returns as a playable character in Mario Golf: World Tour, and now has his own purchasable ball and set of clubs that a Mii can equip and use. His costume is available when all the Star Coins for the Cheep Cheep Lagoon challenges are collected. In the Castle Club's Royal Room, he is seen spinning on one leg while holding up the other, next to Daisy.

For his eagle animation, he puts a rose in between his teeth, turns a spotlight on by clapping, makes several poses, and pirouettes. He ends the animation by holding the rose out in a dramatic fashion. The birdie animation is similar, but without the rose, and the par animation involves pirouetting. Finally, his bogey animations has him yelling out in a disappointed manner, and the double bogey animation involves him making expressions of disappointment under a dim spotlight, and then falling down a hole.

Mario Golf: Super Rush
Waluigi reappears as a playable character in Mario Golf: Super Rush, sporting a golfing outfit in place of his overalls. Like Wario, he is an All-Around character. He has lower Power and Stamina than Wario, but he has a better Speed than him. His Special Shot is known as the Slim Stinger and his Special Dash is known as the Dance-Off Dash.

Mario Kart: Double Dash!!
Waluigi makes his first appearance in the Mario Kart series in Mario Kart: Double Dash!! as a playable character. In the game, he is available from the start, and is classified as a middleweight character. The Waluigi Racer is Waluigi's personal kart, and his default partner is Wario. Waluigi and Wario both share a special item, the Bob-omb. He also has his own course, Waluigi Stadium, which is the last course in the Flower Cup. Due to this, Waluigi appears in the course's icon, and his face appears on a "Waluigi Kart" sign in the course's background.

Mario Kart DS
Waluigi also appears in Mario Kart DS. He is an unlockable playable character. Again, he is a middleweight racer. Waluigi has three karts, which are the Standard WL, the Zipper, and the Gold Mantis. He is unlocked if the player completes the Retro Grand Prix in 100cc. He again has his own course, Waluigi Pinball, which is the third track of the Flower Cup. A large figure of Waluigi appears near the end of the course.

Mario Kart Arcade GP 2
Waluigi appears in the arcade game, Mario Kart Arcade GP 2. He is one of the playable all-around racers. Waluigi also has his own cup, the Waluigi Cup, which has two courses: Stadium Arena and Waluigi Stadium. Both courses feature Waluigi's icon on their respective sign above the Starting Grid.

Mario Kart Wii
In Mario Kart Wii, Waluigi is a starting, playable character. While Waluigi typically is in the middleweight class, he is categorized as a large-sized character in this game, likely due to his tall height. Also, in Mario Kart Wii, Waluigi is given an acceleration bonus that is tied with that of Toad. He also provides a drift bonus and a small off-road bonus. Waluigi Stadium from Mario Kart: Double Dash!! also returns as a retro course in the Banana Cup, though the course no longer has an icon.

Mario Kart 7
Although Waluigi does not appear as a playable racer in Mario Kart 7, his likeness does appear in the returning DS Waluigi Pinball course.

Mario Kart Arcade GP DX
Waluigi later appears in Mario Kart Arcade GP DX, this time as an unlockable character. Unlike the previous games, which have either made him a middleweight or, in the case of Mario Kart Wii, a heavyweight racer, Mario Kart Arcade GP DX places Waluigi as a lightweight character.

Mario Kart 8 / Mario Kart 8 Deluxe
Waluigi returns in Mario Kart 8 as a playable racer where he is available from the start. While classified as a heavyweight, Waluigi is actually one of the lighter heavyweights, sacrificing some speed and weight to boost acceleration, handling, and grip a little; he shares this trait with Donkey Kong, Rosalina, and Roy Koopa.

Waluigi reappears in the Nintendo Switch port Mario Kart 8 Deluxe. He now only shares stats with Donkey Kong and Roy.

Mario Kart Tour
"All aboard."

- Waluigi (Bus Driver)

Waluigi reappears in Mario Kart Tour as a playable character, where he is classified as a Super driver in said game. Waluigi's special item is the Double Bob-ombs. His self-titled course, Waluigi Pinball, returns from Mario Kart DS; the figure of Waluigi is now a moving cutout. The London Tour introduces a bus driver variant of Waluigi, known as Waluigi (Bus Driver), in which he wears a pair of plaid pants, a matching cap, a white dress shirt, and a striped necktie. Waluigi (Bus Driver)'s special item is the Triple Bananas. He also has a vampire-themed variant known as Waluigi (Vampire) that debuted in the 2021 Halloween Tour. Waluigi (Vampire)'s special item is the Bob-omb Cannon. He has his own Team Rally tour with Wario which he won in, known as the Wario vs. Waluigi Tour.

Mario Baseball series
Waluigi appears as a captain in Mario Superstar Baseball. He also appears as a captain in the game's sequel, Mario Super Sluggers. Whenever Waluigi charges up his hits in this game, they tend to have less power instead of more, though it has increased accuracy. Waluigi sports relatively high pitching stats in Mario Superstar Baseball, and even though Princess Peach and Boo have higher pitching stats in Mario Super Sluggers, Waluigi's pitching stats are still relatively high, and it is tied with his fielding stats.

Mario Superstar Baseball
In Mario Superstar Baseball, Wario gets an invitation to Bowser's baseball tournament. With the help of his teammates, Waluigi and Donkey Kong, he advances to the finals, where he faces Mario's team. During the game, Waluigi attempts to slide into a home run, but slides too short and is tagged out. In the end, Wario's team loses the tournament. Waluigi later reappears in the last cutscene, on Bowser's team, along with Wario.

Waluigi is a Technique character. His pitching stat is outstanding, rivaled only by Bowser. As a result, Waluigi has a quick fastball. Waluigi has a Laser Beam that can help prevent characters running home, although it is slower than other Laser Beams, and a Super Jump that can help catch high balls. Waluigi's other stats are below average.

Waluigi's Power Shot is the Liar Ball. In Challenge Mode, it can be unlocked only by purchasing the Whiskered Eggplant. While pitching, Waluigi throws both a regular baseball and an eggplant to confuse the batter of their target; when batting, Waluigi hits both an eggplant and a baseball, confusing the fielders of which ball to catch.

Mario Super Sluggers
Waluigi and Wario hatch yet another scheme to harm the Mario Bros. in Mario Super Sluggers. While Mario is hitting Bob-ombs shot from a pitching machine, Wario and Waluigi sneak up and load a Bullet Bill into it. Just as the Bullet Bill is about to hit Mario, Bowser jumps in front of Mario and whacks the Bullet Bill back to Wario and Waluigi, launching them high into the sky.

Waluigi has one of the highest pitching and fielding abilities, but he has one of the smallest hitboxes for his normal swings. He is left-handed for both batting and fielding, just like in the predecessor. However, unlike the predecessor, Waluigi's star pitches and star swings are not affiliated with eggplants. Waluigi's Star Pitch is once again the Liar Ball, which, instead of having the effect from the previous game, has him throwing a large baseball, which turns back to normal size upon reaching the batter; this can cause the batter to lose their timing with the swing. Waluigi's Star Swing is the Liar Swing, which makes the baseball travel in a zig-zag path through the air.

Dance Dance Revolution: Mario Mix
Waluigi plays the role of an antagonist in Dance Dance Revolution: Mario Mix. During the game, he steals the Music Keys from Truffle Tower. Waluigi tries to use the keys to make himself the best dancer so he can "hypnotize the rhythmless masses" with his moves and "flood the world with chaos." Waluigi, however, gives three of the Music Keys to other "bosses", retaining only one. He attacks Mario (or Luigi) and Toad with a barrage of Bob-ombs after the heroes travel to Truffle Tower to confront him, causing the heroes fly down a Warp Pipe. Eventually, after the two engage in a dance-off, Mario (or Luigi) defeats Waluigi and recovers the first Music Key.

Mario Strikers series
Waluigi appears as a soccer captain in Super Mario Strikers and its sequel Mario Strikers Charged. Waluigi is a captain of the offensive variety in Super Mario Strikers, which means his Super Strike gauge is easier to land on the light green area of the gauge while more difficult to land on the dark green area of the gauge. Waluigi's purple attire has a number 0 on it and his Super Strike is known as the Drop Rocket. There is also a robot modeled after Waluigi known as Robotic Nightmare, which forms the Super Team.

In Mario Strikers Charged, Waluigi is instead a defensive captain, sharing this trait with Princess Daisy. Due to this, Waluigi has great movement speed and a long tackle, however, he is poor at shooting and passing. His Super Ability, Wall-Luigi!, has him create purple vines to block his opponents. His running speed also increases, and also uses these kind of vines in his Mega Strike as a whip to hit the ball with. Much like the original, he wears a purple uniform with a 0 on it and now has a Bluegrass theme. In the game's Striker Challenges mode, Waluigi plays against Luigi in the Storm Cup, and must defeat him by three or more goals in order to advance through the tourney.

Mario Hoops 3-on-3
Waluigi also appears as a playable, starting character in Mario Hoops 3-on-3. He is classified as technical. Waluigi's Special Shot is the Twist Dunk which can be done if the player taps the letter "W" twice.

In the Nintendo 3DS version of the game, Waluigi is included in the Tricksters group, meaning that he is only playable in certain events. In the Story Mode, Waluigi first appears testing out some binoculars (which he calls "Waluigiscopes") that he plans to use to spy on Luigi. After Waluigi scares away some Shy Guys, Metal Sonic arrives and accidentally breaks the binoculars, and Waluigi challenges him to an event. Waluigi wins, and chases Metal Sonic when he tries to escape, eventually losing him but finding Wario, and the pair decide to find Metal Sonic and Dr. Eggman together. They succeed and defeat them in an event, and Waluigi distracts them while Wario breaks the Fog machine, and the pair then try to get some compensation from Dr. Eggman. Waluigi and Wario later discover that they had been chasing a hologram of Dr. Eggman, and later appear to call Mario, Luigi, Sonic and Tails when they face Bowser and Dr. Eggman to support the Heroes and remind Dr. Eggman that they want some compensation, as well as later appearing at the opening ceremony. Waluigi also appears in the bonus episode Dr. Eggman's Robots, where Dr. Eggman convinces him to compete in an event against Metal Sonic, which Waluigi loses.

In the Nintendo 3DS version, Waluigi is exclusively playable in the Long Jump and BMX events. Waluigi is playable as a Skill-type character in all events in Mario & Sonic at the Rio 2016 Olympic Games Arcade Edition, but has recommended events of Rhythmic Gymnastics and Long Jump.

Mario & Sonic at the Olympic Games Tokyo 2020

Mario Sports Mix
Waluigi appears in Mario Sports Mix, where he is classified as a technical type character. His technique stat is very high, but his other stats are fairly low. Waluigi's Special Shot features him throwing up to four balls/pucks. Each shot that connects with the goal is counted, and is worth one point each (this adds up to four points if all shots connect). In dodgeball, Waluigi's Special Shot can launch up to four attacks on his opponents.

While serving in volleyball, Waluigi's serves can go only in a straight line. In dodgeball, Waluigi evades dodgeball attacks by spinning his body.

Mario Sports Superstars
Waluigi returns as a playable character in Mario Sports Superstars. In most sports he is a Technique type player, giving him the edge in skills such as shot accuracy or horse control. In tennis, however, Waluigi is classified as the sole Defensive player, as per his appearances in the Mario Tennis series. In golf, his default drive is 210 yards, and his shot travels at a medium height in a draw trajectory.

Dr. Mario World
Waluigi appears in Dr. Mario World, where he is playable as Dr. Waluigi. Dr. Waluigi can be unlocked through the Staffing menu randomly like most of the unlockable doctors, but he can be unlocked after beating World 6's Special Stage since version 1.2.0, though beating the stage prior to the update will allow him to be obtainable through the doc box. His skill in stage mode is to eliminate 10 dust viruses or other objects hidden inside dust clouds. If no dust cloud is present, the skill will instead eliminate a random virus or a random object if no viruses are found. In versus mode, Dr. Waluigi's skill changes 3 viruses (2 viruses prior to version 2.2.0) in the opponent's stage into dust viruses at level 1, while at higher levels it covers more viruses inside dust at 6, 9, 12 and 15 in levels 2 to 5 (4, 6, 8 and 10 respectively prior to version 2.2.0), with the skill charging slightly faster at the highest level.

Other appearances and references
Waluigi was featured as a recurring character in Wario's Warehouse, a series of articles on the Nintendo of Europe website dealing with various games on Nintendo platforms (not necessarily games with Nintendo characters).

Waluigi was one of the Mario franchise characters to appear as spaces in the board game Nintendo Monopoly. Taking the place of Mediterranean Avenue, Waluigi was the least expensive character to purchase; therefore, he was also one of the least profitable characters. The cost to purchase him was $60.

In UNO Super Mario, Waluigi is pictured on the 4 card.

Waluigi's outfit appears in Nintendo Land, where it is worn by the third Mii player in Luigi's Ghost Mansion.

In the 28th volume of Super Mario-Kun, he appears in the Mario Party 3 arc. In the arc, he dresses up as the Millennium Star to scam the group out of their stamps. This works, and he constantly throws Poison Mushrooms to slow them down. Tumble, however, controls Mario with a remote control and knocks Waluigi into his own pile of Poison Mushrooms, getting their stamps back.

Waluigi also makes an appearance in Super Mario Maker, where he is an unlockable costume that can be used by grabbing a Mystery Mushroom.

In the Super Mario Mash-up in Minecraft, Waluigi appears as a playable skin.

The game Mario + Rabbids Kingdom Battle features a character known as Bwaluigi, a Rabbid dressed as Waluigi. A figure of Waluigi can also be seen in the game's introductory cutscene.

In Super Mario Odyssey, Mario can unlock and wear a Waluigi outfit via his amiibo or collecting enough Power Moons.

In WarioWare Gold, Waluigi appears as a crude drawing if the player scans his amiibo during Wario's amiibo Sketch, an appearance shared with most Nintendo characters with amiibo. This is Waluigi's only appearance in a Wario title, despite being depicted as his partner in many Mario spinoffs.

Physical description and traits
Waluigi's outfit includes a purple undershirt under usually very dark indigo overalls (which are occasionally pure black), orange shoes, and a purple cap that covers his short, brown hair. He has a large, pink nose, a thin mustache which is straight (horizontal) and pointed up at the edge, and gray eyes, his eyes being surrounded by light blue rings. He also has long limbs and a skinny torso. The yellow symbol on his hat and gloves is a vertical mirror image of Luigi's "L" which forms a "Γ", just as Wario wears a "W" in contrast to Mario's "M". "Γ" is also the Greek letter Gamma, which is pronounced similarly to "G".

Just like his partner, Waluigi is the extreme form of his rival. While Luigi is tall and skinny, Waluigi is taller and skinnier, just as Wario is obese in contrast to Mario. According to the Wario's Warehouse site, Wario routinely puts Waluigi on a rack to make him even taller. Luigi's facial elements are also exaggerated in Waluigi. Waluigi has a very sharp jaw and a pointy chin. Waluigi's sharp, handlebar mustache is an exaggeration of Luigi's soft and fluffy mustache. Many bios describing him in Mario sports games mention (and poke fun at) his features, including his sharp jaw, lanky proportions, pointy nose, and flat feet.

Waluigi's clothing also is similar how Mario and Luigi's color scheme is somewhat the same. Mario and Luigi have the similar colored pants, with their signature colors being opposites (red and green). With Wario and Waluigi, the signature colors are still opposites (yellow and purple), and their pants are not exactly matching, but they are a different shade (most of the time) like Mario and Luigi's, as Luigi's pants are just slightly darker. On a side note, Waluigi has appeared wearing black pants at times, which was more common in his earlier appearances.

Waluigi's appearance gets altered in the Super Smash Bros. series. In Super Smash Bros. Brawl, Waluigi has a monotone, realistic appearance which is supported by his overalls featuring denim textures. Waluigi also wears brown shoes instead of his usual orange ones. In Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U, Waluigi's appearance is more vibrant and cartoonish, better resembling his main Mario depiction. Waluigi's shoes are also their typical orange color, instead of being brown in the previous game. Waluigi's appearance in Super Smash Bros. Ultimate is essentially a combination of the two, due to wearing his current orange shoes, while retaining a subdued color scheme and detailed overalls from  Super Smash Bros. Brawl, but not to the same extent as said game.

In Super Mario Strikers, Waluigi wears a soccer uniform. His short-sleeve jersey and shorts are purple and black, with some white and purple stripes. His gloves are white and grey. His cleats are also purple and grey with white stripes, and they both include his logo. He also wears purple socks. The jersey also has "Waluigi" on the back, and both the front and back have the number 0 on it. In Mario Strikers Charged, this outfit has additional armour. The jersey is no longer short sleeved, and his gloves are entirely white, and part of them are shaped like cogs. His socks are now grey pieces of armour, and his cleats now have yellow lines and yellow studs. The front of the armour now includes his team icon. In both games' official artwork, Waluigi's midriff is slightly exposed, though in-game this only occurs in Mario Strikers Charged. This makes Waluigi the only male human character in the franchise to have worn a top which exposes the midriff.

In Mario Tennis Aces, Waluigi has a tennis outift. This include a short sleeved, purple polo shirt, dark blue shorts, orange sneakers, purple socks, and a purple visor with his logo on it.

In Mario & Sonic at the Olympic Games Tokyo 2020, Waluigi wears different clothing depending on the event. He can wear a purple top with white stripes, which, depending on the event, may be sleeveless, with black shorts, purple socks, and orange sneakers, a purple, white, and black wetsuit where he is barefooted, a karate gi, be shirtless wearing nothing but black swim trunks, his hat, and his gloves, he can wear a red suit with white pants and tall black boots, or a white outfit with purple stripes where he also wears his orange sneakers, and in certain events his wears his normal outfit.

Waluigi received a High-End variant called Waluigi (Bus Driver) in the London Tour in Mario Kart Tour. In this outfit, Waluigi wears red, white, and green plaid pants and a red and white plaid hat. His shirt is white with grey stripes, and he wears a purple, white, and yellow tie with his icon on it. Finally, his suspenders are now brown, and his shoes are now a dark red.

Waluigi's outfit is sometimes referenced without directly referencing the character himself. In Paper Mario: The Thousand-Year Door, by wearing both the "L" Emblem (Luigi) and the "W" Emblem (Wario) together, Mario's outfit becomes a purple undershirt and black overalls. The same can be done in Super Smash Bros. Brawl by switching Luigi's costume color, and in Super Smash Bros. for Nintendo 3DS / Wii U or Super Smash Bros. Ultimate with both Mario and Luigi.

Speech
Like fellow Mario characters Mario, Luigi, and Wario, Waluigi is portrayed by Charles Martinet. Waluigi speaks with a strong Italian accent, just like the aforementioned characters, though he speaks in a considerably menacing tone. Waluigi, like Wario, is more verbose in the Mario games than most other characters, due to consistently speaking in full sentences. Waluigi mostly drops the "-a"s during contractions, as evidenced by several cutscenes in the Mario sports titles. However, there are exceptions, such as in Mario Kart Wii, where Waluigi will say "Let's-a go!" or "I'm-a gonna win!" when selecting him. However, there are times where Waluigi's voice acting is limited, in which case, he has in-game text to show what he's saying. In this case, Waluigi speaks intelligibly, but with slang. Waluigi drops the "g"'s in his sentences, or makes use of the word "ain't" on a frequent basis. Waluigi also has a habit of name-calling, since he consistently calls other characters "fools" or "idiots", as well as saying "Hey, dummy!" to his own teammates in Mario Strikers Charged. In many of his appearances, Waluigi makes a "WAA!" sound whenever he loses, or gets hurt from hazards and other characters' actions; this sound, as well as Waluigi frequently calling his opponents "cheaters", are recognizable aspects of his speech.

Personality
Waluigi is personified as a comic relief character and a boastful, ill-tempered foil to the more humble and gentle Luigi. He has bad chemistry with most other characters besides Wario, and is an openly rude and mean-spirited troublemaker. He has a perpetual scowl and is quick to anger, with earlier bios stating that he dislikes others being happy. In his one outing as a central antagonist in Dance Dance Revolution: Mario Mix, Waluigi claims that his reason for obtaining the Music Keys is to be the best dancer in the world, while bragging about using his power to spread chaos and control "the masses". In Mario Tennis Aces, Waluigi points out that his and Wario's reasons for attaining Lucien was so that they could become the best tennis players in the world. Waluigi's original bio in Mario Tennis also pointed out that he seeked to become as popular and as beloved as the Mario Brothers. His victory celebrations often highlight his self-aggrandizing nature and vanity, and occasionally contain vulgar elements as well, such as in Super Mario Strikers where one of his victory animations involve him performing a.

In the Mario Party series except for Mario Party 3, Waluigi abandons his arrogance to play fairly against his opponents; this is also the case for Wario. However, his victory animations still depict him as somewhat of a boastful character, due to him ranting about "being a superstar."

However, despite his overconfidence, Waluigi is also characterized by the great amount of self-pity he displays at other times. According to his voice actor Charles Martinet, Waluigi feels that good things are always happening to others and not to him, causing him great frustration. Martinet considers his self-pity to be "the cornerstone of Waluigi's character", such as how he constantly points out his own disadvantages and is quick to attribute his losses to his opponents cheating, while hypocritically taking pride in his own cheating. While Waluigi has many unsavory characteristics and appears aggressive at times, Martinet has nevertheless stated that he prefers to play up Waluigi's more conceited and self-pitying traits, as he feels that direct hostility is unfitting for Mario villains. In Mario Super Sluggers, Waluigi shows a bit more sportsmanship; after his scout mission is cleared, he subtly states the gang cheated but commends them for their sneakiness, and congratulates them when they beat the Wario Muscles in a ball game along with accepting the player's decline for one. As a comic relief character, he is often given comical and nonsensical animations, often displaying very poor sportsmanship, being quick to taunt his opponents and cheer for himself, while at the same time scowling in resentment for any progress made by his opponents. In Wario's Warehouse, Wario often portrays Waluigi as extremely stupid, often making idiotic and foolish decisions. However, this contrasts with most of his other descriptions which depict him as the more cunning of the two.

According to the trophy description in Super Smash Bros Melee, he also puts a lot of effort into his antagonistic schemes, although in the end, he never manages to succeed against his rivals. In Super Mario Odyssey, the Waluigi Suit's description claims "This outfit makes you want to lurk in the shadows, waiting for a turn in the spotlight.", either further defining Waluigi to be envious of the Mario Bros, or a likely reference to Waluigi never being a major, or important character. The Waluigi hat's description also says "It's rarely worn", likely alluding to Waluigi's few and insignificant appearances.

Waluigi has been shown as quite secretive about his personal life and has demonstrated a more cynical and skeptical point of view compared to the other characters, as even his oldest descriptions mentioned his egotism and his outsider status in the Mushroom Kingdom. However, recent games have played up Waluigi's hardworking and less malicious personality traits, as shown in Mario & Sonic at the Rio 2016 Olympic Games when he sardonically warns the player that people will not cheer on them forever just because they win medals, and in Mario Golf: World Tour when he interacts with the player character to either tell them to not let their victory get to their heads, or that they should be honest with themselves and happy because they earned it. Additionally, he remarks that his favorite thing to do in between rounds is just to relax and have fun.

Etymology
Since Waluigi has the same first two letters of Wario, Waluigi's name may be considered a clunky offshoot of Wario's name. Waluigi actually has a complex Japanese etymology with many meanings that refer to Waluigi's personality. In Japanese, the "r" and "l" make the same sound, so Luigi can be pronounced in Japanese as "Ruīji", and Waluigi can be pronounced as "Waruīji". "Waruīji" is a portmanteau of "warui", the Japanese word for "bad" or "evil", and "Ruīji", making his name literally Evil Luigi or Bad Luigi. However, "warui" can also mean "poor", "hateful", "abominable" and "inferior", representing Waluigi's reputation in the Mushroom Kingdom and his place compared to Mario and Luigi. Additionally, warui, also means to make a condescending apology, instead of a polite apology, referring to Waluigi's arrogance. "Waruiji" (with short "i") is also an anagram of the Japanese word "ijiwaru", which translates to "someone who is bad" or "mean-spirited". "Ijiwaru" also translates into other harsh words such as "sadistic", "malicious", and "unkind".

Powers and abilities
Waluigi is talented at a variety of sports, including baseball and soccer. Because of this sports talent, Waluigi has many abilities displayed throughout his appearances. However, he is usually a technical character in most of the Mario spin-offs. These range from simple actions, such as jumps, punches, and kicks, to unusual actions, such as spinning to make a small tornado, creating thorny vines, and swimming in midair.

In most of his appearances, Waluigi is consistently a Technique character, possessing neither too much strength or speed, and relying on a special trait that would give him the edge. In Mario Kart: Double Dash!!, Mario Kart DS, and Mario Kart Arcade GP 2, Waluigi is a medium weight, balanced character, but in Mario Kart Wii onward Waluigi is among the heavier characters. In the Mario Strikers series, he is an offensive character in the first game, and an defensive character in the second game. Due to his long limbs, he is classified as a Defensive character in Mario Power Tennis.

Waluigi's standard abilities include jumping, punching, and kicking. His legs are shown to be particularly powerful, as he easily defeats Bowser with a kick in Mario Party 3, and he is able to stomp characters into the ground in the Super Smash Bros. games. He shows his leg strength in Super Mario Strikers, with his Drop Rocket technique. In addition, Waluigi is demonstrated to be an great jumper. His stats are seen to come close to Luigi's jumping skills, if not surpassing it. In Mario Strikers Charged, Waluigi demonstrates excellent speed, being the fastest character alongside Daisy. His speed is doubled when he uses the Wall-Luigi! skill, enabling him to cross the field in a very short time. However, some games portray Waluigi as slow and weak, for balance purposes.

Waluigi also has a variety of abilities. In Mario Power Tennis, Waluigi can distort his body into the shape of his emblem and create a tornado, which can drive his opponent away. In Mario Hoops 3-on-3, he also creates tornadoes simply by dribbling the ball around himself. In Mario Strikers Charged, Waluigi shows the ability to summon and control thorny, purple vines, which he uses for his Wall-Luigi! Super Ability. He also uses them as a whip in his Mega Strike. In the same game, in his Deke, he also demonstrates to be capable of teleporting in purple puffs of smoke. In Mario And Sonic At The London 2012 Olympic Games, Waluigi displays the ability to use his "Γ" symbol as an energy projectile.

Alongside the power to mask the Whiskered Eggplant as a baseball, Waluigi, in Mario Super Sluggers displays powers with magical and tricky natures. His special pitch in Mario Super Sluggers is the Liar Ball. His Star Swing, the Liar Swing, consists of him hitting the ball and making it zig-zag during its path. In Super Mario Strikers, Waluigi's Super Strike, the Drop Rocket, consists of him surrounding himself with purple smoke and kicking the ball, covering it with a smoke trail

In the way of weaponry, Waluigi prefers the Bob-omb. In Mario Party 3, Waluigi uses a Piranha Plant in battle, and his board, Waluigi's Island, is seen filled with Piranha Plants. In Mario Party 7, Waluigi uses Professor E. Gadd's Coin Vacuum Orb to steal a random amount of Coins from his opponents. Waluigi's special pitch in Mario Superstar Baseball is the Liar Ball, which allows him to throw two balls, one of them being a Whiskered Eggplant.

Relationships
Waluigi has been portrayed as Luigi's main rival since his first appearance in Mario Tennis, where the two challenge, mock and glare at each other. The Mario Tennis Japanese website states that Waluigi resents that Luigi is more liked than he is, going so far as to hate him for it and wishing to defeat him and Mario in order to take their place and become liked and respected himself. This is also seen in the Nintendo 3DS version of Mario & Sonic at the London 2012 Olympic Games where Waluigi stalks his rival and states that he is going to be the "greatest superstar in the world" after he defeats Luigi. The two also share bad chemistry in Mario Superstar Baseball. Another aspect of Waluigi's rivalry with Luigi is that both share apparently a romantic interest in Princess Daisy. Waluigi's crush and the resulting soft spot he has for the princess was stated in the official Mario Party 4 Prima guide, and when partnered up in the series, their team names include "Awkward Date," "Double Facers," and "Skinny Stars," although there is little evidence otherwise that confirms this relationship. Daisy, meanwhile, does not return Waluigi's affections, however, and the two share bad chemistry in Mario Superstar Baseball.

While Waluigi and Wario sometimes bicker, their relationship overall seems to be a positive one, with them sharing good chemistry in the baseball games and often teaming up in sports events and spinoff titles. The two share many aspects of their personalities and even looks, although the exact relationship between Wario and Waluigi is somewhat ambiguous. The original Nintendo website, while premiering Mario Tennis and introducing Waluigi, stated that Wario was his "big brother." Certain Nintendo of Europe sources such as Wario's Warehouse or the Mario Kart DS website suggest that they are siblings, with the Prima guide for Mario Tennis outright stating that Waluigi is "Wario's little brother," but the DS version of Mario & Sonic at the Olympic Winter Games contradicts this idea by stating that they are instead cousins under trivia notes, and a news brief that can be found in Blizland outright states that they are not brothers. Waluigi's trophies in both Super Smash Bros. Melee and Super Smash Bros. Brawl indicate that their relationship is intended to be unclear; Wario merely calls Waluigi his "traitor friend" when the two were briefly in opposition in Mario Super Sluggers, and Charles Martinet, who voices both characters, has stated his belief that they are simply "two nice, evil guys who found each other." A question for the Athlete Characters Quiz in the Wii version of Mario & Sonic at the London 2012 Olympic Games revolves around Wario's and Waluigi's noses, and its announcer, Omochao, offhandedly says that the two of them are not related. Even though the relationship is not clarified in the Wii U version of Mario & Sonic at the Rio 2016 Olympic Games, a line of dialogue from a Mii states again that Waluigi is not Wario's brother. In Mario & Sonic at the Olympic Games Tokyo 2020, there is a trivia fact about Waluigi which states that he is not Wario's brother. On the other hand, Nintendo's official Japanese bio of Waluigi only states that Wario and Waluigi do not appear to be brothers.

Aside from Wario, Waluigi is not shown to have any friends in the games. Like Wario, Waluigi is on almost as bad terms with Bowser as with most other characters in the series. While Bowser, Wario, and Waluigi team up to try and defeat Mario in the opening cutscene of Mario Power Tennis, they are in conflict more often, such as Bowser blocking the unscrupulous duo from destroying their shared foe Mario (for the Koopa King wanted this pleasure for himself) in Mario Super Sluggers, or Bowser and Waluigi fighting over the Mischief Star Stamp (with the latter curb-stomping the former) in Mario Party 3. As seen in Fortune Street, Bowser thinks very lowly of Waluigi, being quick to point out Waluigi's bad reputation and appearance. Waluigi in Fortune Street is shown to be confused by others being nice to him, and thinks they are trying to trick him into a false sense of security. However, he has demonstrated a lot less malice when interacting with the player characters, indicating that he mostly just hates the Mario Bros. in particular.

In addition, it has been implied that Waluigi is on particularly bad terms with the yellow virus from the Dr. Mario series. In a June 12, 2020 post made by the official Dr. Mario World social media accounts, which announces an in-game event where 20 of the then-available 21 doctors had their staffing rates increased by 1.5, the virus suggests that one doctor was omitted (Dr. Waluigi ) because they do not get along.
