Koopa King

The Koopa King is Bowser's kart in Mario Kart: Double Dash!! and is a default kart. It is a very big and heavy kart and one of two six-wheelers in the game, the other being the Barrel Train.

According to the in-game stats, the Koopa King is the fastest kart in the game, as well as having the weakest acceleration, making it a bad pick for simple courses, such as Baby Park. It is also one of the heaviest karts in the game; its weight is tied with the Piranha Pipes and Boo Pipes.

In actuality, the Koopa King accelerates a bit better than the DK Jumbo and its acceleration actually ties with the Green Fire, despite it having one star less. Also, despite having a five star speed stat, the Koopa King's speed is really tied with those of the Green Fire, Bullet Blaster, DK Jumbo, Piranha Pipes, and Parade Kart. Lastly, the Barrel Train can actually outspeed the Koopa King, but that is mostly due to its bad traction.

Trivia

 * The Koopa King and the Parade Kart are unique in that they are the only karts with an engine sound belonging only to them; all other karts' engine sounds are shared with at least one other kart.
