Debuting in Super Mario World, these buff men look like the Koopa football players from the SMW Cartoon. The only difference is that Chucks are actually human. There are five kinds of Chucks. They are:
- Chargin' Chuck: The most common of the Chucks, he'll just run at Mario and pray that he doesn't get foiled yet again by Mario's spin jump.
- Splittin' Chuck: This one will split into 3 Chargin' Chucks and do their thing.
- Pitchin' Chuck: Unlike the last two, This one doesn't run. Instead, he pitches beanballs at Mario, hoping to hit him.
- Diggin' Chuck: Only in cave levels, This Chuck will dig through the ground to find rocks, which he (tries to) drops on Mario.
- Puntin' Chuck: The rarest of all Chucks, he punts footballs at Mario(though not far at all.)
