Bullet Blaster

The Bullet Blaster is Bowser Jr.'s unlockable kart in Mario Kart: Double Dash!!. It is shaped like a Banzai Bill.

Mario Kart: Double Dash!!
Like Diddy Kong's Barrel Train, the Bullet Blaster is one of the fastest lightweight karts in the game. It is also the lightest kart in the game, and can be knocked around by any other kart of any weight class. Another one of the kart's good stats is its acceleration, which is lower than the regular lightweight kart, but still better than a heavyweight. Its horn makes the sound of a noisemaker. The Bullet Blaster is unlocked by completing the Special Cup in 50cc.

In terms of its actual stats, while the Bullet Blaster does have a three star acceleration stat, it is one of the weaker accelerating karts, equalling the Red Fire, Turbo Birdo, and Parade Kart. Also, its top speed is tied with that of the Barrel Train, DK Jumbo, and Piranha Pipes. Lastly, although the Bullet Blaster is a lightweight kart, it is tied with the Koopa King for having the slowest off-road speed in the game.

Mario Kart Tour
The Bullet Blaster returns in Mario Kart Tour, where it appears as a Normal kart. Its design has been updated to be more in line with the Banzai Bill's appearances post-New Super Mario Bros., but with the same yellow rotor as in Double Dash!!. It appears to be equipped with the Roller tires, mixing components from its appearances from Mario Kart 7 (black tire treads), Mario Kart 8 and Mario Kart 8 Deluxe (yellow center). Rocket Starts are more powerful and yield more points while using this kart. The game also introduces a red variant, named the Bull's-Eye Banzai.

Super Smash Bros. Brawl
The Bullet Blaster also appears in Super Smash Bros. Brawl as a sticker. When used on a fighter in The Subspace Emissary, it increases their launch power by 50 points.

Trivia

 * In Battle Mode, for some unknown reason, the Goo-Goo Buggy's weight is tied with this kart. In any other game modes though, the Goo-Goo Buggy can easily push the Bullet Blaster around.
 * The Bullet Bike and Road Jetter in Mario Kart Wii and Mario Kart Arcade GP DX are similar to the Bullet Blaster.
 * The Bullet Blaster's yellow rotor makes it resemble the Banzai Bills seen on Princess Peach's Castle in Super Smash Bros. Melee and Super Smash Bros. Ultimate.
 * In the North American version of Super Smash Bros. Brawl, the Bullet Bill trophy mistakenly gives the name "Bullet Blaster" for its special cannon. This is corrected to "Bill Blaster" in the PAL version.
 * The Bullet Blaster, Red Fire, and Green Fire share the same engine sound.
