Sawtooth is a nasty piece of work. This massive, cannibalistic freak chops up his meals with the massive, serrated grinder he has in place of a jaw, which also imparts him with his characteristic speech impediment. Luckily for his prey, he's overconfident—fatally so.
Marvel Comics continuity
Sawtooth and his cohorts, Guttersnipe and Meathook, came across the Mini-Con Broadside in their underground domain. Sawtooth made clear his intent to devour the tiny Transformer, but Broadside objected quite forcefully, blowing up the Mutant's head.
- Sawtooth's body—with its tank-like lower half and lantern "jaw"—is generally modeled after the "Guts Dozer" boss from the old NES video game Mega Man 2.
