Galaxy Colosseum

Galaxy Colosseum (known as Galaxy Arena in the British English version) is a battle stage that appears in Mario Kart Wii, exclusively during the online Tournaments game mode. The battle stage is a round platform floating in outer space, modeled after similar platforms in Super Mario Galaxy and Rainbow Road; in addition, the size of the battle stage would be adjusted depending on the tournament objective.

Three tournaments took place on the arena, each with their own unique objectives. In the first tournament, players had to compete for the fastest time by knocking a total of four giant Spiky Topmen off of the arena's edge using only Triple Mushrooms. Players could knock them away with a Mushroom boost. In the second tournament, the outer rings of the arena broke off, and players had to send six Spiky Topmen off of the stage. In the third tournament, some Topmen could run away, and the player could use any Kart, Bike, or control scheme.

Due to the ending of the Nintendo Wi-Fi Connection service and subsequent end of Tournaments mode, it is no longer possible to play on this course through normal means.

Trivia

 * During the second tournament, a misplaced Item Box was located at the very bottom of the course.
