Lance Corporal Levi
Louise & Tina Belcher
Hmm, that's really all I can think of right now.
Batman, Mr. Freeze, Eric von Zipper come to mind
And others. I'll fall in love with pretty much any anti-hero and sympathetic villain.
I can't list all of them but I can try... Lol
I know there are a lot more but I won't put them all down. This is just at the top of my head.
Do I have to list them all? XD
Boba Fett, Peter Petrelli, Iron Man, Captain America, Loki, Dumbledore, Jack Sparrow, Sherlock Holmes, the Doctor, the Master, Ferris Bueller, Elle Woods, and so many others but those are the big ones off the top of my head :)
Lestat de Lioncourt, Remus Lupin, and Horatio
