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 when he pulls out the jawbreaker cannon. The weapon burns his foes with caustic salt-based corrosives. His weapon mode has the additional ability of creating tidal waves by use of the powerful tail.
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.
Notes

- Overbite's weapon mode is described in the text and art as being double-barreled. He is also described as having a double-barreled freeze beam blaster. It seems likely that at some point in development, his toy was going to include a double-barreled weapon, but the actual toy does not.
