Red Shell

The Red Shell is an item that has consistently been in every Mario Kart game. It targets the nearest racer ahead of the user. Once it hits its target, it will flip their kart. It has two variants: the Triple Red Shell and Quintuple Red Shell.

Koopa Kart series
The Red Shell appears in every game in the Koopa Kart series, serving the same role as in Mario Kart. In most games, it can be obtained in the top eight positions, while in Koopa Kart Wii and Koopa Kart 8, it is obtainable in the top twelve positions. Starting from Koopa Kart DS, the Red Shell is able to hit players on the side, and as of Koopa Kart Wii, if its target has already been hit, it will slow down until the player is vulnerable so it can hit properly.
