The 'Hush" thread got me thinking..
Why the hell hasn't Mr Freeze ever taken the frozen body of his wife nora and placed it in a Lazarus Pit???
Why didn't Superman get Deadman to possess the body of Doomsday and stop him before he killed all those people..??? If they know Lex Luthor is guilty of so many crimes why don't they have Deadman possess Luthor and make him do something impeachable or jailable openly in teh view of the public eye???
Post Crisis..Talia gives birth to Batman's son in an in continuity story, and gives it up for adoption... years later Denny O'Neil strikes it arbitrarily from the Batman Canon..
Why didn't Amazo ever use Martian manhunter's powers to follow the super-heroes back to their homes and uncover their secret identities..???Thus effectively making them all impotent if they had secret IDs...
