Bowser Jr.

"Someday, when I'm bigger, I wanna fight that Mario again!"

- Bowser Jr.

Bowser Jr. (sometimes written as Bowser Junior) is Bowser's eighth child. He is the youngest of Bowser's eight children and the Koopa King's favorite offspring (at least, for the time being). His other seven children, who used to help Bowser's plots, have now grown up and sometimes conquered whole kingdoms themselves. Bowser Jr., on the other hand, is allowed to accompany his father in various schemes, such as Super Mario Sunshine and New Super Mario Bros.. Bowser Jr. seems to be the perfect son for Bowser, as he wants to do nothing but his father's will (i.e. kidnap Peach and destroy Mario). The evil king himself even shows emotions toward his new son, a side of Bowser that is rarely seen (However the Koopalings have never appeared in games socializing with Bowser and Bowser Jr., except in New Super Mario Bros. Wii, and he did not appear in the cartoons or the comics.)

''Super Mario Sunshine
Bowser Jr. first appeared in Super Mario Sunshine as the game's main antagonist. Before the events of the game, Bowser Jr. somehow acquired the Magic Paintbrush, a special brush that can magically create sticky paint-like goop, from the scientist Professor E. Gadd. Bowser Jr is also in possession of a bandanna emblazoned with a logo resembling Mario's nose and face that apparently lets him assume the form of Mario. However, the appearance can only be a watery-blue color. Bowser Jr. uses this ability to assume the identity Shadow Mario. As Shadow Mario, Bowser Jr. painted magical graffiti all over the tropical resort Isle Delfino, framing Mario for the crimes.

At the same time, Mario, Peach, and Toadsworth were heading to the island for some much needed holidays. However, as soon as the Toad Express landed at the island's airstrip, Mario battled a Polluted Piranha Plant, using his new partner F.L.U.D.D.. Afterwards, the Delfino Police arrest Mario. After his trial, Mario was found guilty of vandalizing the island and was punished with cleaning up the island with F.L.U.D.D. (which was also designed by Professor E. Gadd). As Mario began cleaning Delfino Plaza by cleaning up the Grand Pianta Statue, Princess Peach was kidnapped by Bowser Jr. (in his Shadow Mario disguise). Mario managed to save Peach rather quickly, and then chased Shadow Mario to Bianco Hills. His cleaning up continued through various regions of Isle Delfino, during which Shadow Mario kidnapped Peach again, this time while Mario was away from Delfino Plaza or buying a Shine Sprite at the boathouse.

Shadow Mario took the Princess to Pinna Park, the island's theme park, which was occupied by Bowser's forces. The young Koopa jumped into the cockpit of the gigantic Mecha Bowser and waited for Mario's inevitable arrival. Like clockwork, Mario arrived and battled the mechanical monstrosity. After a long battle, Mario overcame the powerful Mecha Bowser. Shadow Mario then revealed his true identity. As it turned out, Bowser Jr. was told by his father that Princess Peach was his mother and that she was kidnapped by the "evil" Mario. As such, Bowser Jr. tried to frame Mario by tagging the island as the Mario look-a-like Shadow Mario. Thus, Mario would be put in prison and the young Koopa could rescue his "mama". With his origin revealed, Bowser Jr. escaped by converting what was left of Mecha Bowser into a hot-air balloon and flying it, with Peach in tow, to Corona Mountain, where his father had been relaxing.

However, Bowser Jr. did not stay with his father at the volcano, and continued to harass Mario in his Shadow Mario disguise. Bowser Jr. attempted to run off with Shine Sprites, F.L.U.D.D. nozzles, and even a Yoshi Egg, but he is eventually stopped by Mario every time. Eventually, after Mario defeated Shadow Mario in all of the main areas of the game, the path to Corona Mountain was revealed.

When Mario reached the top of Corona Mountain, the final fight between Mario and Bowser Jr. began. However, Junior was not fighting alone this time; he had his massive father to help him. The three fighters battled in a colossal bathtub high above the ground. As Mario and Bowser duke it out, Junior aided his father by firing Bullet Bills at their nemesis. Eventually, father and son were defeated and Mario escaped the volcano with Peach.

In the end, Bowser admitted to his son that he deceived him. In a rare case of emotion, Bowser remorsefully told Bowser Jr. that Peach was not his mother. However, Bowser Jr. admitted he knew Peach was not his mother, and (although his father tricked him) says he wants to "fight that Mario again". Bowser, seeing so much of himself in his heir, smiled. Together, the two plotted their next plan to defeat Mario and capture Peach, after relaxing for a certain amount of time.

Bowser Jr.'s first appearance was the only one to feature the Mario-style bandanna.

''New Super Mario Bros.
In New Super Mario Bros., Bowser and Bowser Jr. enacted their new plan to kidnap Princess Peach and defeat Mario. While Bowser's forces occupied various regions, Bowser Jr. was sent to retrieve Peach. To do this, Junior summoned a lightning cloud to set fire to Princess Peach's Castle, causing Mario to go investigate and thus leaving Peach all by herself. As a result, the young Koopa sneaked in and captured the Princess. As such, Mario gave chase, battling Bowser Jr. throughout the game. Junior acted a lot like the Boom Booms of Super Mario Bros. 3, as he was the sole mid-boss of the game's various worlds. Like Boom Boom, Bowser Jr. could be defeated with three jumps to the head.

In New Super Mario Bros., Bowser Jr. was the boss of every tower. His attack pattern depended on how he wore his bandanna. If it was hanging loose, Bowser Jr. would jump and charge at Mario and could be defeated by simple jump attacks. If he wore the bandanna over his mouth, Bowser Jr. would throw Koopa Shells at Mario and duck into his shell whenever Mario comes near, preventing jump attacks from working. In this form, Mario had to hit Bowser Jr. with a Koopa Shell before he could be jumped on. Fireballs and Blue Shells were also very effective against the young Koopa, no matter what appearance he took.

During the events of the game, Bowser was the boss of the first world. However, the Koopa King fell into a pit of lava. As such, Bowser, in a sense, perished and became a Dry Bones-like monster called Dry Bowser. While Bowser was a member of the undead, Bowser Jr. had to hold together the Koopa Troop in his father's place. Surprisingly, the Koopa Troop remained united under his leadership. Bowser Jr. even remains loyal to his father. Instead of taking complete leadership of the kingdom, Bowser Jr. revived his father by throwing him into a pot filled with some form of magic potion, restoring the Koopa King to his former self. However, Bowser was much larger than before and more powerful.

In the end, Bowser Jr. and his resurrected father fought Mario in an epic battle for Princess Peach. However, like Super Mario Sunshine, both father and son were defeated, and Peach was saved once again. During the game's ending, Bowser Jr. was seen dragging his unconscious father across the ground, bringing him home so the two could plot against Mario for a second time. He also broke the Fourth Wall at one point, roaring at the player.

''Super Mario Galaxy
Appearing as the secondary antagonist, Bowser Jr. guarded three of the Grand Stars in Super Mario Galaxy. He appeared first in Bowser Jr.'s Robot Reactor, where he summoned Megaleg to attack Mario. He later appeared in Bowser Jr.'s Airship Armada in his small personal airship to fight Mario. He was also seen in Bowser Jr.'s Lava Reactor where he summoned a more powerful King Kaliente to attack.

Bowser Jr. was not seen again until Mario reaches Bowser's Galaxy Reactor, where he was shown keeping Peach on his airship. While Mario marched up the steps to confront Bowser, Jr. fired cannonballs that collapsed the steps. He then watched the final battle while keeping Peach. After Bowser was defeated, the galaxy started to go haywire. Bowser Jr. fell out of his airship and into his father's sun. Later, however, he was shown alive and dancing back in the Mushroom Kingdom on a Airship in the water.

''New Super Mario Bros. Wii
Bowser Jr. makes another appearance in the sequel to New Super Mario Bros., New Super Mario Bros. Wii. This is the first game in which he appears along with Bowser's other seven children. As his father's apparent favorite child, Bowser Jr. seemed to be leading the Koopalings in this adventure, and got a Koopa Clown Car similar to that of his father, although it was smaller, instead of a magic wand like his siblings. In the beginning of the game, it is revealed that Bowser Jr., along with the Koopalings, arrived to Princess Peach's castle on her birthday disguised as a birthday cake. Bowser Jr. and his siblings emerged and kidnapped the Princess by loading her onto the airship. From there, the Koopalings (along with Jr.) made a flight to Bowser's castle via the airship with Mario, Luigi, Blue Toad and Yellow Toad closely following them in an attempt to rescue Peach. This is also the first game where he is shown to breathe fireballs. Unlike how Bowser Jr. was fought ten times in New Super Mario Bros., he was only fought three times; all three times being on an Airship.

In the first battle with Jr., he used his Clown Car. He flied up and the only possible way to attack him was to use the Propeller Block in order to spin up to his height and jump on him. The Koopa King's son had finally mastered the art of breathing fire, and when his fire hit the ground, it created a large blaze there. He had to be hit three times to be defeated.

In the second battle, he used his much more broken Clown Car to battle. Luckily, Mario found a Mario Car to use in combat. The Mario Car must be flown up by the player and used to knock Jr. into the Electric Fence on the walls of the room. He must be hit three times to be defeated.

In the third battle, Mario Ground Pounded the floor upon entering the room, sending a wave through the floor that knocked over Jr.'s Clown Car. Bowser Jr. turned around and saw his father's Clown Car. Kicking his destroyed Clown Car aside, he jumped into the larger version. Using his father's Clown Car, Jr. dropped large mines on the field. A ground pound must be used on the wavy floor to lob the mine back up and damage the Clown Car. Bowser Jr. could now fire more than one fireball in a row, and they created blazing obstacles on the floor. In addition, these fireballs would home in on Mario. Bowser Jr. must be hit three times.

Bowser Jr. could be seen in the ending, communicating with Larry Koopa. The two watched their siblings help their Dad. After lifting their unconscious father, he geot hoisted up and soon after, Bowser's Castle collapsed on them.

''Super Mario Galaxy 2
Bowser Jr. makes an appearance in Super Mario Galaxy 2, aiding his father once again, as in the first game.

His first appearance in Bowser Jr.'s Fiery Flotilla was a brief one, where he summoned Gobblegut to the battlefield for Mario's fight for the first Grand Star. He himself did battle with Mario and Yoshi later in the game by piloting the Megahammer robot, for the third Grand Star. Later, the Boomsday Machine was Jr.'s vehicle of choice, and guarded the fifth Grand Star. Once Mario defeated Bowser Jr.'s Boomsday Machine, it exploded, sending Bowser Jr. flying into space. He was not seen afterward for the remainder of the game, and it is unknown what exactly happened to him but he survived since he appeared in again in Mario Sports Mix.

Mario faced Bowser Jr. up to four times in this game, with two of the fights being under the Daredevil Comet conditions.

''Mario Golf: Toadstool Tour
Bowser Jr. is said to have spent the majority of his childhood practicing golf on his dad's private course, making him a skilled golfer. He uses these talents in Mario Golf: Toadstool Tour, where he is a hidden character. For some reason, Shadow Mario also is a playable character in this game. It is unknown if this Shadow Mario is an alternate form of Bowser Jr. or someone else donning the shadowy disguise. Perhaps, this Shadow Mario is Il Piantissimo, the tropical island racer who finds the Magic Paintbrush at the end of Super Mario Sunshine.

''Mario Kart: Double Dash!!
Bowser Jr. appears as his father's partner in Mario Kart: Double Dash!!. Bowser Jr. is a lightweight, while his father is a heavyweight. The two make a deadly racing pair, as they can both use Bowser Shells to mow down opponents. Occasionally, this attack backfires, as the shell can ricochet backwards and hit the father and son team. His personal kart is the Bullet Blaster, which can be unlocked by winning the Special Cup in 50cc. In the manual, the reason why Bowser Jr. is in the race is because he had been misbehaving, and his father believes that this would set him straight.

Interestingly enough, while Bowser's Koopa King is very heavy (one of the three heaviest karts in the game), Bowser Jr.'s Bullet Blaster is very light (lightest kart in the game).

Mario Kart Wii
Bowser Jr. reappears as an unlockable character in Mario Kart Wii. He can be unlocked by getting at least 1 Star Rank in every Retro 100cc Cup. Unlike in Double Dash!!, he is a middle sized character and races solo, like everyone else in the game. Bowser Jr.'s stat bonuses only boost the off-road and mini-turbo stats by a small amount. Therefore, he has the smallest number of stat bonuses among all the playable characters in the game. Bowser Jr.'s emblem appears in several parts of the city in Moonview Highway.

''Mario Power Tennis
Bowser Jr. appears as his father's doubles partner in Mario Power Tennis. The young Koopa can use the Magic Paintbrush to add power to his swings or confuse his opponents with tennis balls made of paint. Whether or not it's the same Magic Brush from Super Mario Sunshine is unknown.

Mario Baseball series
Bowser Jr. appears in Mario Superstar Baseball and Mario Super Sluggers where he is a powerful batter, but his running speed is a bit lacking. In these games, Bowser Jr. is shown to be left-handed (though there's an option to play right-handed).

In Super Sluggers, Jr. has his own stadium, which happens to be his own room. At night, it changes into Bowser's Castle. His Magic Paintbrush is his bat in Super Sluggers, which he uses to blind the batter with paint blotches or knocks the opposing team's members out with paint. In Challenge Mode, he is responsible for taking over all of the stadiums on Baseball Kingdom, only to be beaten in every stadium by Mario and the gang.

When Bowser is defeated for the second time, the other captains invite them to a celebration. Bowser refuses, but Bowser Jr. tells Bowser that he wants to have fun, which forces them to go (though the two only get a small portion of food).

Bowser Jr. had good batting and running abilities in Mario Super Sluggers, but his pitching was only average, and his fielding skills were pretty weak. His running is his best skill which upgrades his fielding abilities by far and his jumping almost matches Diddy Kong's in height.

''Mario Hoops 3-on-3
Bowser Jr. later appears as a playable character in Mario Hoops 3-on-3. Unlike his father, he is a default character. Bowser Jr. is a speedy character who slams dunk by whirling his arm around in a circle and then slamming the ball in. Bowser Jr.'s Super Shot is the Graffiti Dunk, which consists of Bowser Jr. using his Magic Paintbrush and covering the basketball in Graffiti and then hitting it towards the basket.

''Mario Strikers Charged Football
Bowser Jr. is also an unlockable character in Mario Strikers Charged Football. He is an Offensive Captain, unlike his father, who is a Power Captain. Bowser Jr. is unlocked by beating the Fire Cup, which also involves beating Bowser Jr. as well. Bowser Jr.'s whining abilities are shown in this game where his screams reach supersonic levels. His Super Ability, Sonic Roar!, allows him to shrink all players he hits by using a large sound wave. His Mega Strike also uses sound waves. In this game, Bowser Jr. wears a collar similar to the one Bowser wears. His trademark bandanna, however, is absent.

''Mario Party DS
Bowser Jr. made his Mario Party debut in Mario Party DS, where he helped his father in Story Mode, though he only has one line in the game. Bowser Jr. also appears in the Rocket Rascals mini-game occasionally to cause trouble.

''Super Smash Bros. Brawl
Though Bowser Jr. was not a playable character or Assist Trophy, he made several cameos in Super Smash Bros. Brawl. He appears as a trophy that is based on his current appearance, and he is briefly mentioned in Bowser's trophy information. He also has several stickers depicting him from several games. Junior's artwork from Super Mario Sunshine is an attack type, medium sized sticker. It's area of effect is the tail and damage is +25. The only characters who can use it are Yoshi, Pikachu, Diddy Kong, and Pokémon Trainer. His second sticker is his artwork from Mario Superstar Baseball.

''Mario & Sonic at the Olympic Winter Games
Bowser Jr. made his debut in the Mario & Sonic series in the second game installment, Mario & Sonic at the Olympic Winter Games. He is a well-rounded character, with stats more in favor of power and skill in the Wii version; his stats in the DS version, however, are more balanced, with power being his best stat. His special move is the same as his dads.

''Mario Sports Mix
Bowser Jr. appeared as a speed character in Mario Sports Mix. His speed is very high, while having average power. However, his technique attribute is very low. He has his very own stadium called Bowser Jr. Blvd..

Character Description
Bowser Jr.'s skin tone is the same as most of the Koopalings, with the same yellow and tan skin complexion, as well as a light green head. Junior has one, fang-like tooth in the upper corner of the side of his snout. He also has a ribbed, padded stomach and padded feet. His mouth is wide, puffy, and convexed, with a large snout. He has small, circular eyes that are black in color. Junior has small spikes on each side of his head, each being circled with orange rings. Junior's hairstyle is a top-ponytail held by a metal hair-tie. It is fiery in both color and appearance, similar to his father's hair. He also has thick eyebrows of the same fashion.

Bowser Jr. is physically powerful like his father in spite of his small frame. His exact size varies from game to game like his father's, but he usually appears bigger than his older brother, Lemmy, and has a chubby frame similar to Ludwig's. He is shown to be fast, as well as skilled, though at times he may be given varied stats.

Jr. is portrayed as wearing few items of clothing, similar to his relatives. His main article of clothing is a white bib that's decorated with drawn-on fangs and worn like a mask. Rather than wearing the spiked cuffs the male Koopalings have, Jr. has spikeless, metal cuffs on his wrists. His shell design is very similar to his father's. Jr.'s shell is green, lined with a white encasing, and the multiple, short spikes are circled with orange rings.

Personality and Traits
Bowser Jr. can be summed up as a bold and energetic troublemaker. His trouble making side is seen as he tricks Mario in both Super Mario Sunshine and New Super Mario Bros. According to Mario Kart Wii, Bowser Jr. inherited his father's bad attitude, evident in his motto ("Grin and bear it. When that don't work, grin and crush it."). He is also bratty, spoiled, and short tempered, though in Mario Party DS it is stated he has a lonely side. His favorite hobbies are stealing cookies, causing trouble for people, and scribbling (which may explain the widespread graffiti that was made at Isle Delfino). However, he seems determined to defeat Mario in a fair fight in order to prove his power.

Bowser
Bowser Jr. idolizes his father and strives to be like him. Bowser tends to treat Bowser Jr. as a minion sometimes, but usually shows a bit more emotion towards him. When Bowser admits he conned Jr. in Sunshine, Jr. admitted he knew all along and forgave his father, showing how they trust each other. Bowser also never gets frustrated at his son when he fails, something that happens often with his other minions. While Bowser does care for his son, his selfishness and greed seems to overshadow this; in Super Mario Galaxy, Bowser grieved over the impending destruction of his galaxy rather than thinking about the welfare of his own son. Nevertheless, Bowser Jr. and Bowser have a very strong bond and are seen together as partners in various sports titles.

Koopalings
Bowser Jr.'s relationship with his brothers and sister is for the moment unknown. So far, it is known that he is the youngest and smallest of the eight children. He also ranks slightly above them, making the seven others technically subordinate to him (this does not stop some of them from abandoning him on the airship, which may be intentional or accidental). However, he is known to help them, by dropping them of at their respective castles in his airship as well as watching over them. The only scene in which he directly interacts with the other Koopalings is after the credits in New Super Mario Bros Wii, where he points a waking up Larry Koopa at the rest of the Koopalings, who are lifting up an unconscious Bowser, and they both proceed to help them.

Mario
"Someday, when I'm bigger, I wanna fight that Mario again!"

- Bowser Jr.

Bowser Jr. was told by his father Mario was evil, and took his "Mama" away. He has since been trying to cause Mario trouble, which brings him joy. But at the end of Super Mario Sunshine, Bowser tells his son that Peach really is not his mama. He has attempted twice to stop Mario by himself mainly, and has had help by his father in some ways, such as use of the Koopa Troop and weaponry.

Princess Peach
"I know, she's not really my Mama."

- Bowser Jr.

Bowser Jr. seems to have no mother, though he is seen wishing that Peach would play a maternal role in his life, shown when he called her 'mama' in Mario Superstar Baseball even though he knows she is not related to him. In his Brawl trophy it was revealed that the reason he had kidnapped her in Super Mario Sunshine and in New Super Mario Bros. was because he felt strongly about her. In  Super Mario Sunshine, Jr. tried to get Peach to join him and Bowser in their slime tub, but Peach politely refused the offer. In Super Mario Galaxy, Jr. also kept Peach with him in his airship while Bowser fought Mario.

''Bowser Jr. has been causing trouble for Mario since they met at Isle Delfino, doing the bidding of his father, the great Koopa King Bowser. When Mario gives chase to Bowser across the universe, Bowser Jr. tries to intercept the plumber and make his father proud. But does the little Koopa underling have the guts to really stop the hero of the Mushroom Kingdom?''

Portrayals
Bowser Jr. is voiced by Dolores Rogers. For some reason, on Tara Strong's official website, the voice actress is said to have voiced Junior in Super Mario Sunshine, even though she is not listed in the game's credits. She however, voiced Bowser Jr.'s older brothers Hip and Hop on The Adventures of Super Mario Bros. 3 and the Super Mario World cartoon. In Mario Strikers Charged Football, Super Mario Galaxy, Mario Kart Wii, Super Mario Galaxy 2, and Mario Sports Mix, he is voiced by Caety Sagoian.

Trivia

 * According to the Mario Power Tennis official website, Bowser Jr. resides at "48 Lava Cul-De-Sac, Magma Manor."
 * In Mario & Luigi: Partners in Time, Baby Bowser looks exactly like Bowser Jr.. However, his bandana is different.
 * Ironically, while his siblings were fought on Airships in Super Mario Bros. 3 and Bowser Jr. was fought in towers in New Super Mario Bros., they swapped roles in New Super Mario Bros. Wii, where Bowser Jr. is fought only on the Airships and the Koopalings are encountered in the towers of each world.
 * Bowser Jr. is the only one of Bowser's children who is not named after a real person, but rather, a fictional character.
 * Like his father, he seems to have an inconsistent size. He was smallest in Super Mario Sunshine and some spin-offs, but as of New Super Mario Bros. and its sequel he is roughly Mario's size. In Super Mario Galaxy he has grown considerably, towering over Princess Peach.
 * Bowser Jr. is never seen as an opponent in Mario Strikers Charged Football's Challenge Mode.
 * In New Super Mario Bros. Wii, Bowser Jr. always wears his bandanna on his face when in the presence of his siblings, never showing his face when around them. Coincidentally, these are also the only instances in the entire game where Bowser Jr. wears his bandanna in this manner.
 * Ever since Diddy Kong appeared in the Mario spin offs, Bowser Jr. also appeared along with him. However, while Bowser Jr. is in Mario & Sonic at the Olympic Winter Games, Diddy Kong is not playable for some reason. Likewise, Diddy Kong is in Super Smash Bros. Brawl, but Bowser Jr. isn't.
 * Bowser Jr. is left-handed. This is because Shigeru Miyamoto prefers his left hand and likes making left-handed characters; Link is also left-handed.
 * However, despite being a lefty, he appears on the right handed side of the batting field in Mario Super Sluggers. He also plays right-handed, by default, in Mario Power Tennis.
