Knuckle Joe is a friend of Party Ninja. He makes his first appearence in Kirby Super Star. When Kirby sucks him up, he gets the Fighter ability.
- In Kirby Super Star, he is the only enemy that gives the Fighter ability.
- It is confusing how first before Knuckle Joe becomes an helper in Kirby Super Star(and the remake), his clothes become blue, red in the sub-game Helper to Hero, and pink when an enemy.
