Many characters on the Avengers were once villains or could easily be called such. Hawkeye, Black Widow, Sandman, Vision, Hulk, Red Hulk, Quicksilver, Scarlet Witch, Ares, Spiderock, Winter Soldier, ect.
If they were to add a villain to the Avengers team, who would be a good idea? I mean, the bad guy can't be unstable or unredeemable, so Red Skull, Green Goblin,.Bullseye and Mister Sinister are no's.
If I had to think of some
Shocker is a professional, as oppose to a psychotic nutcase. He might decide one day that good pays better than evil, or perhaps he just doesn't want to have Spiderock maul him.
Isn't Magneto some sort of Uncanny traitor or something? Perhaps when all of this blows over he could try and become an Avenger.
got any ideas?
