Guttersnipe may be smaller than most Underworld mutants, but what he lacks in size he makes up for in sheer malevolence. This sawed-off little punk enjoys nothing more than hunting down anyone foolish enough to enter the abandoned sublevels of Cybertron he calls home—but only if they struggle a little first. S'no fun, otherwise.
While uglier than the average Cybertronian, he is fairly normal-looking compared to most mutants, save the gun barrel and mess of wires that take the place of his left optic.
Marvel Comics continuity
Guttersnipe and his bigger buddies Meathook and Sawtooth found the Mini-Con Broadside trespassing in the Underworld. When their would-be snack killed Sawtooth, Guttersnipe moved in to avenge him, but was instead fatally mauled by Overbite. In a final indignity, Overbite tore off Guttersnipe's face and wore it, much to the amusement of Snarl.
