Which super villains do you think are broken and how would you fix them? Which super villains do think are in rut, story wise and how would you get them out of it?
Personally I think the Wizard's in a real rut, forming Frightful Four to defeat the Ff for the past 40 years, he should set his sights a little lower, he would be a dangerous street level villain, but the FF seem out of his league. He should at least get a clue and try to form an Evil Eight next time.
..Killgrave the Purple Man is now a character who can only be used in certain circumstances after Alias established him as a mind-controller who gets off on sexually humiliating female superheroes. There have been one or two Marvel head-grabbers who've gone part of the way down that route before (e.g. Mesmero) but not as far. Now whenever he appears in a book with a female hero the writer has to explain why she's still wearing clothes and not sitting on his lap.
Perhaps change this by having his powers transferred to a woman?
