The entire Legion of Super Heroes. They've been a mess since the Crisis on Infinite Earths. I want Colossal Boy back, among other things.
Wonder Girl/Troia/Donna troy is the same way. Was a great Titan until Crisis came along. What's amazing is Marv and George wrote both and then George revamped Wonder Woman and didn't include Wonder Girl in it.
Ms. Marvel was fine until they canned her book. She was terrible as Binary and doesn't make any sense as Warbird.
Is Thanos a hero or villain? I don't get it.
New Warriors are a mess, as are X-Force, Generation X and the Defenders. (Though Kurt Busiek has laid the groundwork of a revamp now that he's brought back Valkyrie and Nighthawk.)
Metal Men need Gold back and Doc Magnus as Doc Magnus, not as a member of the group.
