Article on Super Mario Wiki Bowser Jr.

Bowser Jr. (クッパJr., Koopa Junior) is the son of Bowser and a major villain in the Mario series.


Bowser Jr. is the mischievous son of Bowser and the prince of the Koopas. He bears a striking resemblance to his father when he was a child, having beady eyes, a rounded snout with fewer contours, and hair tied in a small ponytail.

He debuted in Super Mario Sunshine, where he painted over most of Isle Delfino with a Magic Paintbrush he somehow obtained from Professor E. Gadd. The "paint" was often referred to as "goop". Bowser Jr.'s graffiti caused the Shine Sprites scattered about, causing its sunlight to recede. Bowser Jr. did these things disguised as Mario, tricking the denizens of Isle Delfino into thinking he was the culprit. In disguise, Bowser Jr. appears similar to Mario, but has a higher-pitched voice and a gelatinous, dark blue body with glowing red eyes. The disguise, referred to as Shadow Mario, is activated by a blue neckerchief with Mario's signature mustache drawn on it (in later games starting with Mario Golf: Toadstool Tour, Bowser Jr.'s neckerchief is white and has a drawing of a ferocious mouth instead).

Bowser Jr. was also convinced by his father that Princess Peach was his mother and that Mario had taken her from him, thus setting his plan into motion; by framing Mario, he attempts numerous times to kidnap the princess, who he refers to as his "mama". By the end of Super Mario Sunshine, however, Bowser Jr. reveals that he knew Peach wasn't really his mother, while still expressing a desire to fight Mario like his papa.

Bowser Jr. became a landmark character after Super Mario Sunshine, appearing as a playable character in multiple spin-off games (his first being Mario Golf: Toadstool Tour), as well as having a recurring role as Bowser's elite soldier in the New Super Mario Bros. games, where he commands the Koopalings. In several games, he uses a smaller variant of his father's famous Koopa Clown Car, officially named the Junior Clown Car in Mario & Luigi: Dream Team. Most notably, he appears in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, a remake of Mario & Luigi: Bowser's Inside Story, where he takes center stage as the main protagonist of the newly-added Bowser Jr.'s Journey mode.

Later Mario games would explore more facets of Bowser Jr.'s character. In Super Mario Galaxy and subsequent games, Jr. has been shown to invent and pilot large battle machines of various sorts, such as the Junior Clown Car. He is also able to hack computer systems and transform areas into military outposts with factories as seen in Mario + Rabbids Kingdom Battle. His mechanical and technological prowess show through in his Super Smash Bros. moveset, which shows him summoning various tools and gadgets from within the Clown Car. Mario & Luigi: Paper Jam explores Jr.'s personality in further detail, showing that, while he may be the child of a villain, he is ultimately a lonely Koopa who desires friends above anything else. Other games—such as Mario + Rabbids Kingdom Battle, Paper Mario: The Origami King, and Super Mario 3D World + Bowser's Fury—show that Bowser Jr. cares deeply about his father.

Bowser Jr. has complicated relationships with the main cast. Despite knowing that Peach is not his real mother, he will still assist Bowser in his attempts to capture and marry her. Peach herself sees Bowser Jr. as a misguided child that needs a proper parent, particularly not Bowser. Though Bowser Jr. is antagonistic for most playable characters, he especially despises Mario for constantly getting in the way. This animosity was strongest in Sunshine where he actively sought to take Mario down. Later installments toned this hatred down, with the two fighting only when their paths cross. Bowser Jr. even occasionally shows a willingness to team up with Mario, albeit only when out of need. When such a mission is complete, he goes right back to his antagonizing ways. While Mario will not hesitate to fight out of self-defense and can sometimes be cold towards him, he has no ill will towards Bowser Jr. and is more than willing to help him whenever their interests are aligned.

In Super Mario Sunshine, Bowser Jr.'s voice is performed by Dolores Rogers. Caety Sagoian has provided his voice in later games since Mario Strikers Charged.

In Super Smash Bros. Brawl[edit]

Bowser Jr. appears as a trophy and as two stickers.

Bowser's son, who appears in Super Mario Sunshine calling Princess Peach his mother—he feels so strongly about her that he kidnaps her. Somewhat spoiled by his father, Bowser Jr. comes off as being on the selfish side. His bib is decorated with drawn-on fangs and worn like a mask—it's most likely an effort to appear more menacing.

In Super Smash Bros. 4[edit]

As a playable character[edit]

Main article: Bowser Jr. (SSB4)
Bowser Jr. as he appears in Super Smash Bros. 4.

Bowser Jr. was unofficially revealed as a playable character in SSB4 by a leak of the ESRB review video.[1] He was shown to fight in his Junior Clown Car, using boxing gloves to attack (inspired by his Clown Car in New Super Mario Bros. U, but the gloves protrude with metal extenders instead of being attached to arms). He can also drop Mechakoopas and fire cannonballs. The seven Koopalings also appear as alternate costumes for him. His Final Smash has him briefly transform into his Shadow Mario form, which then swipes the screen with the Magic Brush, creating a large X, which hurts all opponents that it touches.

Currently, Bowser Jr. is placed 48th out of 55 on the tier list, placing him in the F tier. His Clown Kart Dash special gives him a fantastic approaching option thanks to its speed and usefulness in starting combos. He also comes with some powerful finishers that can potentially KO opponents below 100%. Although he's classed as a heavyweight, his aerial game is respectable thanks to his good air mobility and ability to juggle opponents with his aerials. Despite these strengths, Bowser Jr. is held back by notable flaws, such as a laggy grab, poor ground mobility, and his recovery in Abandon Ship! is predictable and open to gimps. Bowser Jr.'s weaknesses hold him back from leaving much impact on the competitive scene, having below average results in tournament, though he still has a few dedicated players.


Bowser Jr.
Ntsc Bowser's beloved, spoiled son sports a bandanna with a large mouth drawn on it. Like his father, Bowser Jr. longs to take Mario down. In Smash Bros., he'll fight from inside his heavily armed Junior Clown Car. The Clown Car takes less damage than Bowser Jr., so mind your positioning.
Pal Bowser's probably a big fan of his son, what with him hating Mario just as much as dear old Dad does. The tyke's Junior Clown Car is packed with gadgets and gizmos to throw at enemies! By the way, he's extra vulnerable when he jumps out of it, wouldn't dream of attacking the cute little fella then, would you?

When you use his up special, Bowser Jr. jumps out of the Junior Clown Car, letting it hit opponents. Try to catch opponents with it while you're directly over them to hit them on the head!
