<deep breath.>
1. Alucard (Hellsing). It isn't so much that he pisses me off, as much as people fawn over his "combat abilities." A demonic demon hound for an arm and a nearly limitless supply of souls to regenerate with... yeah. Must take a lot of skill to win those fights.
2. Rip (Hellsing). Millennium has enough problems getting ahead with Zorin being beltsanded to death, they didn't need a childish, nearly-blind rifleman lasting half a fight and dying blushing for reasons no one wants to read into. >>
3. Lelouch (Code Geass). The last person in history to retreat in the middle of a crucial battle to save his girlfriend was Mark Antony. You can find out how he fared on Wikipedia, if you need to know why this is a bad idea.
4. Light Yagami (Death Note). Again, I already hated him enough for his pedestrian concept of "ethics," and then people started supporting him, and now I'm losing my hair at 20. ><
5. Schrodinger (Hellsing). Do I even need to explain why I would hate a pink-eyed, Nazi, neko warrant officer in boy shorts? Yeah, I didn't think so. (He does get a point for being a quantum physics joke, though).
6. Quatre (Gundam Wing). Why the hell did we give one of most powerful machines known to mankind to a pacifist?
7. Misa (Death Note). She's a fangirl of the main character, of the series she's a part of. I got a nosebleed the first time I ran that through my brain from the sheer insanity of it.
8. The entirety of the new FFXIII crew. I've never been a FF fan before, but now that I've seen Girlcloud passed off as an original character, I think I'm going to keep it that way.
9. Roy Mustang (Fullmetal Alchemist). I just don't understand how someone can join the military, and then be shocked and horrified that he had to take lives. Then again, I don't understand how the fans can feel sympathetic.
... I have a lot of hate to spread around. >>
