I'm actually not really interested in who your favorite character is, but rather on the reasons that make you like him/her/it so much. So please don't just leave a name, but list the main reasons that motivate your choice (nice looks, cool powers, interesting personnality, lifestory, etc).
If you are hard pressed to chose an all time favorite, you can also cite some of your favorites.
So, to kick off this thread, here's my favorite character:
Reki, from Haibane Renmei: I like her looks, the multiple layers of her personality, and how these layers show up in details of her everyday behavior, making her more "real" (for instance, the fact that she's a smoking teenager). I also related well to her inner struggles, and enjoyed the way her conflict was brought to a closure.
griffith from berserk
Kusanagi Motoko from SAC. She is very interesting person with incredible skills and strength.
And Lain is a Goddess undoubtedly ^_^
Guts from Berserk. Why? Because he's the strongest motherfucker anyone has ever seen, and without having any extraordinary powers. He's just a normal human bad-ass.
Yomiko Readman from Read or Die. She's a bibliophile with cool abilities, and she's cute and clumsy. I love her!
