Bowser Jr.

Lore & Background

Bowser Jr. first made his mark in Super Mario Sunshine, where he kidnapped Princess Peach and unleashed a tide of ink-covered Goombas across the beaches of Isle Delfino. His motivation was simple and childish: a grudge against Mario, whom he blamed for stealing his father's thunder. Armed with a trusty paintbrush and a fleet of ink-squirting minions, he proved that even the smallest Koopa could throw the Mushroom Kingdom into disarray.

Over the years, the little Koopa has appeared across multiple Mario titles, often serving as a mid-boss or a recurring nuisance. His design—short, round, with a wide grin and a paintbrush strapped to his back—makes him instantly recognizable as Bowser's offspring, yet his personality is far more playful and petty than his father's brute-force tyranny. He is the kid who kicks the dog, not the one who sets the house on fire.

In the Super Smash Bros. universe, Bowser Jr. slots in as a scrappy underdog who has no business being in the same arena as gods and titans. His paintbrush, which in his home games is a tool of mischief, becomes a genuine combat instrument in Smash: a weapon, a platform, a ladder, and a trap all in one. Fans love him for the contrast he brings—tiny, fast, and deceptively dangerous—reminding everyone that the smallest creature in the Koopa Troop can still leave a mess you'll never clean up.

In Their Own Story

The arena hums with the residual energy of a hundred battles. On a cracked stretch of ground that looks suspiciously like a sun-bleached beach, a small green shell bounces into frame. Bowser Jr. skids to a halt, paintbrush already raised, and grins at the towering silhouette across from him. He flicks the brush, and a bright blue blob of paint slaps onto the ground, solidifying into a tiny platform. He hops onto it, then paints another, then another, building a spiraling staircase of color that defies the stage's geometry. His opponent swings a weapon the size of a car. Bowser Jr. is already three paint-blobs up, laughing, leaving a trail of wet blue streaks in the air. The little Koopa doesn't need to be the biggest thing in the room. He just needs to be the one still standing when the paint dries.

FIGHTER DOSSIER: BOWSER JR.

Source Franchise: Super Mario Unlock Method: Downloadable Content in Super Smash Bros. for Nintendo 3DS / Wii U; included in the base roster of Super Smash Bros. Ultimate.

Neutrals: Bowser Jr.'s neutral attack is a rapid sequence of paintbrush swings—short, fast, and low-damage, ideal for spacing and poking. His dash attack is a low brush sweep that can catch grounded opponents. His aerials (forward, back, up, and down) all feature the brush in different arcs, giving him a slightly wider hitbox than his tiny frame suggests. The down air in particular has a noticeable downward trajectory that can be used to punish opponents who jump too high.

Smashes: His forward smash is a committed horizontal brush swing with good range but slow startup. The up smash is a vertical overhead that can anti-air. The down smash is a wide ground-level sweep with strong knockback but a long recovery window, making it a commitment play rather than a safe option.

Specials: All four special moves revolve around paint. The neutral special is a quick brush swing that creates a small paint blob at his feet. The side special launches a paint blob forward that solidifies into a small platform. The up special paints a vertical line upward, allowing him to climb it for recovery. The down special paints a horizontal line that can serve as a temporary platform. These paint objects persist for a short duration and can be used for repositioning, recovery, or setting up combos.

Grabs & Throws: Standard grab with four throw directions. His throws are quick but low-damage, fitting his lightweight role. He is not a throw-heavy character; his game is built around paint manipulation and fast neutral attacks.

Recovery & Quirks: His up special (vertical paint line) gives him solid vertical recovery, but his horizontal recovery is limited. The paint platforms he creates can extend his effective reach, but they disappear after a few seconds, so timing is critical. He is very light, meaning he is easily knocked back and struggles against heavy, high-knockback opponents. His low weight also means he is a juggle target.

Alternate Costumes: Bowser Jr. has multiple alternate color palettes for his outfit and shell, ranging from his classic blue-purple to brighter and darker variants. His paint color changes accordingly.

Combo Properties: His fast neutral attacks chain well into smashes and aerials. The paint platforms can be used to reposition mid-combo, allowing him to follow up an opponent who has been knocked into a vulnerable position. Because his paint objects are temporary, he must commit to his timing rather than relying on persistent stage modifications.

Did You Know?

• Bowser Jr. was introduced as a DLC fighter in Super Smash Bros. for Nintendo 3DS and Wii U, making him one of the later additions to that roster rather than a launch character.
• His entire special-move set is built around the same paintbrush concept from Super Mario Sunshine, where his ink-based attacks were the core of his boss-fight mechanics.
• Despite being Bowser's son, Bowser Jr. has a distinctly different playstyle in Smash—he is a fast, technical lightweight rather than the heavy, power-based fighter his father is.
• The paint platforms he creates in Smash are temporary objects that disappear after a short window, meaning players must time their recovery and repositioning carefully rather than relying on them indefinitely.
