The typical clutz and the comic relief of the team, also serving as the brawn. He is a glutton for food and easily side-tracked by it (the word sandwich making him feel like eating McGoombas). He was shown happily taking an order from Red to destroy Mecha Sonic, showing his love of battle, but screamed in fear soon after learning just how powerful Mecha Sonic is.

Yellow, like the others, wields an axe as his weapon of choice, though his is much larger in size to accommodate his larger body. Oddly, he rarely uses his axe, preferring to fight with his fists and raw physical strength. His signature ability is to combine his fists into one superpowered hammer strong enough to split mountains in half. However, his strength doesn't necessarily imply that he's too slow or heavy, easily chasing Sonic up a mountain and staying in a mid-air battle for the entire duration.
