Ummm....
My fave anime hero.... ASH KETCHUM.
"Pikachu! I choose you!!!!" >=D
"Pika-piiii!" o ^__^ o
No, seriously. I don't know. I'll have to think on this one some more.
But my fave anime villain? Definitely Diva from
Blood+. She's totally evil and completely off her rocker; her mood and way of thinking seem constant but they're also unpredictable. But she's also kind of a sympathetic character once you take into consideration her past and everything, and her wishes for her own personal future. But then when you think about what she's done and everything, your opinion is then thrown into eternal conflict! It's awesome! And she also has an amazingly variable and powerful voice, and sings her own theme song, and her voice is sort of integrated into her powers and everything and it's so wicked sweet. She's her own person and she knows it, and she's not afraid of anything because she is completely assured of her invincibility and all-around supremeness.
....Wow. Firefox says supremeness is actually a word.
Ah, anyway. No spoilers here, go watch the series yourself! Seriously, you won't regret it. And if you do, then don't tell me because I will tell you that something is wrong in your head.
