G.I. Robot and Magnus: Robot Fighter

When I was a kid, I inherited a stack of comics from my older brothers.  They were ninety percent Marvel and DC.  The remaining comics were Archie, Disney and Harvey titles, so the Big Two were my main outlet for super-heroic adventure.  The few Gold Key comics featuring Magnus were an exception, and I was intrigued by this guy who had no connection to the larger comic book universes that I was discovering.  I must not have been the only one because he is a character that never seems to stay down for long.
