Jawbreaker cannon
From MediaWiki

Overbite isn't always satisfied to claw his prey to shreds or to freeze them solid. Sometimes he wants them to suffer. That's he when transforms into his weapon-base mode and pulls out the jawbreaker cannon, a weapon mounted to his head that burns his foes with caustic salt-based corrosives. And when he wants to dish out some serious damage, he converts into his Targetmaster form, a super-sized jawbreaker cannon big enough to be used by Piranacon. For whatever reason, it looks like his exactly freeze beam cannon.
