Maxie Zeus had a really bad day, and he snapped. But he didn't have a regular old nervous breakdown, he started believing he was Zeus, the Greek god. Somehow, this delusion leads him to become a criminal. I've never fully understood why.
But I guess Batman stories need people committing crimes for Batman to stop, and sometimes they need themes. And Maxie Zeus a theme. He really seems like an old school Batman villain that made perfect sense in the stories of the 40s and 50s that seem incredibly campy to the 21st century reader, but Maxie Zeus only dates back to 1979.
Pros: Hmm... anyone have an idea here? I got nothing.
Cons: In my day, crazy people thought they were Napoleon, and that's just how it was, and we liked it. But yeah Maxie Zeus sucks.
How I'd do it: There's only one way to do it, and it entirely depends on casting...
Casting Guesses: Samuel L. Jackson. Think about it. Zeus is a god, not a man, so he doesn't have to be white. And even if he did, Maxie Zeus is crazy and wouldn't care. Plus, Sam Jackson looking all pimp in his Zeus throne, being all "I'm a thunderbolt throwin' motherfucker, motherfucker!" No other actor can pull that off and still look cool.
After The Scarecrow, Ra's Al Ghul, The Joker, and Two-Face, who should be Batman's next enemy in the Batman Begins/The Dark Knight series? Well, as of now we know that Tom Hardy will play Bane and Anne Hathaway will play Catwoman.
Check out the master list for all the villains covered. I've pretty much run out by now. Obviously, there are more Batman villains, but not any of significance that I know of. As of February 2009, no one is confirmed as a villain. Not the Johnny Depp Riddler, not Phillip Seymour Hoffman Penguin, nobody.
