Who's This? No! Not THIS Automan!
How you could have heard of him: He was one of the guys who built Sean McKeever's Enginehead, though you're forgiven for thinking he was Cliff Steele (Robotman). His body was seen in Legionnaires #66 as well.
Example story: Tales of the Unexpected vol.1 #91, his first appearance.
Who else? One a couple of pages later, there's ANOTHER character I really want to check out. And I'm not gonna wait. The Balloon Buster hits the SBG... TOMORROW!
