Chargin' Chuck is a type of Koopa that wears an American Football player uniform. It first appeared in Super Mario World and Super Mario Evolution.
Chucks also appear in Lets-a-go, Mario as enemies. They attack in every way they do in Super Mario World, which includes charging, throwing baseballs, kicking footballs, and dividing into three Chargin' Chucks. The game also introduces the Chuck Suit as a downloadable power-up, which allows the wearer to defeat enemies from the side when running at full speed. Boss Chargin' Chuck is also the leader of the Chargin' Chucks in this game.
