I had to remember which mine was, since I've used Ed from Cowboy Bebop (my LJ default), Kiki and BunBun from Sluggy Freelance, and Garfield at random times. My current avatar is from SG-1 that I snagged from an author in that fandom. It never fails to make me giggle. Now if only I could figure out what episode it's from.

"You need me. You wouldn't be much of a hero without a villain. And you do love being the hero, don't you. The cheering children, the swooning women, you love it so much, it's made you my most reliable accomplice." -- Lex Luthor to Superman, Question Authority, Justice League Unlimited
