Chuck Guys have major differences from Spear Guys. They are colored purple, they lack the grass skirt, their mask is less painted, their shoes are colored black and they have a ponytail on the back of their head, complete with a blue headband. There is a stronger version of the Chuck Guys, named Elite Chuck Guys.
History
Mario & Luigi: Superstar Saga
In Superstar Saga and the 3DS remake, Chuck Guys appear as enemies located in Chucklehuck Woods. In the overworld, they attack Mario and Luigi by throwing their spears at them.
Battle
In battle, they will either charge at a Bro. with their spear (they will hop before attacking), or try to stab the Bro. with its spear. When a Chuck Guy is defeated, the remaining Chuck Guy can call forth another Chuck Guy, although sometimes a Chuck Guy will not appear, resulting in it losing their turn.
Minion Quest: The Search for Bowser
Chuck Guys appear in the side story of the 3DS remake, Minion Quest: The Search for Bowser as enemies, alongside their stronger counterparts, Elite Chuck Guys. They fight as Melee troopers and their Special Skill is Spin Cycle. They are weak against red Koopa Paratroopas.
