Joker, he doesn't need a plan to destroy someone's life

I'm surprised at the general lack of support for Lex Luthor. Yeah, the Joker's batsh*t insane and definitely a top contender, but Luthor's like ... I mean, where do you start with him? He's such a complicated character, one almost impossible to definitively pin down, and the fact that nobody can really figure out what the guy wants and why he does what he does just makes him such an intriguing villain ... plus I think it's pretty impressive how the guy is such a royal pain in Superman (and many others)'s ass, despite the fact that he's so much weaker than him. Yeah, Darkseid and Brainiac get the best of Superman and are great villains too, and same goes for Joker and Batman, but they're inherently able to be. I read a really good article/essay on Luthor once, and I distinctly remember two lines - "Most villains fight men. Luthor is a man trying to fight God." and "Villains in the DC universe might be scared of the Joker, but they're in awe of Luthor b/c he's a cut above them all and they know it."

The poll is over but for the record, I vote Luthor ... with Joker as a solid second.

I have to add that Luthor has to be the most respectable DC Villain in my book (the Billionaire incarnation that is, not Donner's Real Estate Buffoon surrounded version ). On the other hand, I have always LOVED Black Adam. Definitely not THE most powerful entity out there but there's just always been something incredibly... COOL (geek moment) about him!

Joker, for being the sickest of the lot.

Deathstroke, for being the hottest ;o)

Reverse flash is cool, he's all murderous and stuff.
