Which item turns the player into a bullet and drives automatically? The answer is Bullet Bill. In Mario Kart, this powerful item transforms the racer and kart into a huge Bullet Bill that automatically races along the track at high speed. During the transformation, the player is largely guided by the game rather than steering normally, making it especially useful for recovering from a far-behind position.

Bullet Bill is based on the Bullet Bill enemy from the Super Mario series. Bullet Bills are large, fast projectiles launched by Bill Blasters, usually flying horizontally toward Mario. The Mario Kart item turns that familiar enemy into a temporary vehicle, complete with its distinctive angry face and clenched fists.

A common mix-up is confusing Bullet Bill with the Star. The Star grants invincibility and boosts speed while leaving the player in control. Boo makes the racer temporarily invisible and can steal an opponent’s item, while the Mega Mushroom enlarges the character. Bullet Bill is the item that combines automatic movement, great speed, and the ability to knock aside opponents.
