Name This Marvel Villain??
There are a few villains who can do what this guy does, in one way or another, but I ask you: who looks more villain-ish doing it? Like the Masked Marauder, the Corruptor is more of a behind-the-scenes villain who makes well-laid plans and ends up crossing paths with major heroes. His powers have changed from time to time, depending on what writer is handling him. The one thing that stays a constant is his sheer enjoyment of being devious.
In one appearance, he was inadvertently the catalyst for bringing together a new super group, the Rangers, though he really had designs on the Avengers. But the Rangers had their hands full with someone else the Corruptor had, er, corrupted--a certain man-monster who, like the Rangers, also hung around the southwest:
The Rangers didn't make much headway against the Hulk--but the Corruptor was caught off-guard when his pawn unexpectedly changed back to Bruce Banner, which enabled the Rangers to finally capture the villain. Once he was defeated, he was taken out of mothballs a few more times in other titles, but I'm afraid this was another Marvel villain who had major-league ambitions but who nevertheless wound up in the minors.
