So far, I am REALLY hoping that King Tut stays around as a Batman villain. I mean, yes, one could argue that the quota for riddle-leaving villains has already been filled, but he doesn't HAVE to keep doing that - there are any number of niches Tut could fill. Egyptian mythology, a royalty fetish, delusions of godhood (the Pharaohs, after all, were supposed to be living gods) - he could be like the cool, psychotic, Egyptian version of Maxie Zeus! And who wouldn't love that? Besides, he has the advantage over a number of villains already, since his character has been in the public eye for decades due to the '60's TV show. So a lot of people will go 'Oh, yeah - King Tut. Wait, he's a NEW villain? I thought he'd been around for a long time - that's interesting.' There's a hook right there. I tell ya, it'd be like printing money!
