The Legion of Doom had their Fortress in a swamp in the Everglades or some such location. I thought that was a pretty good (by which I mean "evil") idea. Then of course Superman's Fortress of Solitude was at the North Pole, so apparently there's no correlation between alignment and geographic location of one's fortress.
Dude, I don't think anyone would pay $10 for the UN reps.
Hey, it worked for the Joker, Penguin, Riddler, and Catwoman in the 1960s Batman movie! Now if the Joker doesn't know evil, tell me who does? If I were you I'd be paying attention to my evil lessons and taking evil notes instead of contradicting your evil elders. See, that's the problem with evil geniuses today, they think they always think they can do it better than the older generation. I'd like to know how would you improve on Mr. Freeze's plan to kill Batman and Robin by freezing them into giant Slurpie drinks?--huh, Ms. Smarty-Pants?
Maybe if you promised to feed them to sharks or something...
Hmmm--maybe you have been studying your evil lessons after all. Do the sharks have laser beams attached to their foreheads?
