Quartet

Quartet is a robot featured in Archie Comics' Mega Man series and a member of the Star Marshals. Appearing in Issue 42, he was part of a group of Star Marshals who attempted to destroy Ra Moon. While several of his comrades battled Ra Moon's Stardroids, Quartet spotted the evil computer fleeing the battle with an escort of Kuiper Droids. He attacked and destroyed most of the droids, with only the future Shadow Man escaping his wrath. Unfortunately, he was then betrayed by a fellow Star Marshal named Trio, who fatally wounded Quartet and allowed Shadow Man and Ra Moon to escape.
