Oooh!  You could bring in the Basilisk or the Ringer!  Or half the D list villains that got killed off by the Scourge in 616.  ;)<br/><br/>*fondly remembers when Marvel cleaned house by killing off all their silliest villains*<br/><br/>Oh I know who would be the most terrifying villain... STILT MAN!<br/><br/>Apocalypse would surely have to watch himself with Stilty around.  ;D
