Skullbreaker uses the same torso used for all Dragon Hunters except Iron Baron, Arkade, and Jet Jack. His legs also appear on all other Dragon Hunters except Iron Baron and Daddy No Legs, while his head is the same as Arkade's, Dragon Hunter's, Muzzle's, and Talon's. His black hood piece is also used for Muzzle.
- While Skullbreaker's animated appearance has a red hood, in set form it is black.
- Like Arkade and Daddy No Legs, Skullbreaker only appears in one set.
