The Koopa-King is a Heavy Class Kart in Mario Kart: Double Dash!!. This kart is noticeably used mainly for Bowser, seeing how the kart looks like him and is named after his role, being the King of Koopas. It is a standard kart and can be used from the very beginning of the game. The kart is the fastest kart in the whole game, but lacks acceleration, having some of the worst acceleration in the whole game also. This kart does not look related to the Bullet Blaster in any way, but actually is. The reason is because Bowser's son, Bowser Jr. owns this kart.
