Scrounge

Scrounge is an Autobot who knows his gaskets.

Beast Hunters issue 5
Missing an arm, Scrounge went before Iacon's acting commander Snarl to present his side of an incident involving a gasket that may or may not have been several microns different from an ordinary one. His testimony was interrupted first by Snarl's impatience and then by a cataclysmic planetwide restructuring event. Like many of the other damaged Cybertronian survivors, he was apparently made whole again by the planet's reformatting...which did nothing to prevent his destruction under a pile of rubble.
