And I get the pleasure of reviving an old thread...
This actually interested me because I have quite the list of annoying little anime bastards that I would like to get out as well and everybody else's nominees have been very interesting. And because of everyone else before me, I now don't have to watch Trigun.
Asaka Langley Soryu (Neon Genesis Evangelion):
She cool and attractive and everything but I just wished that she would stop being so fake and try to impress everybody. It really gets annoying. And the way she treats Shinji... Damn, girl, we know you like him. Just shut up and let the boy lay his game on you

And another, stop yelling all the damn time!!!
Pan (Dragonball GT):
I don't really think I have to explain this but she has got to be the most annoying character that was spawned from all three of the Dragonball series. Just watching her makes me sick and the sad thing is, she is one the best highlights in GT. (That's probably what makes GT such an unforgivable crap).
Dragonball GT:
Actually, when you think of it, the series is a disgrace. From Pan to the Black Star Dragonballs, Gokou turning into a kid, Goten and Gohan period, Videl (I hate her and Mr. Satan with a passion), Bra

, and they downgraded Vegeta and Piccolo so much, they would have better if they were just killed off (although Piccolo was). So many plotholes and soooo much crammed together that it didn't even try toying with the notion of making sense. And please, don't get me started on Super Saiyan 4...
Yu-Gi-Oh:
To be honest, I used to watch and enjoy the show... before Pegasus was defeated. After that, I might as well be watching DBGT. Every character was annoying with that damned, f***ed up hairstyles. The problems with the show is that they try very hard to shove down our throats that kids who should be doing normal things (like school) are everyday risking their lives to save the world with... CARD GAMES?! At least in Evangelion, it was tolerable to have kids save the world with bio-androids but card-games? W.T.F.? And listening to Tea's friendship speeches has got to be the most embrassing thing in the world of anime...
Pokemon:
Come on! Ash Ketchum's voice is alone enough to hate the show but then there's Misty (did Ash and Misty actually kiss on the show? Just curious...), Team Rocket, and the Pokemon themselves. It was cute at first, but damn, the concept just seems stupid.
Envy (FullMetal Alchemist):
Basically, he (or she. At least in my book) is the only character that I despise in FMA. He killed Hughes, he's always dressed in drag, and he has the most annoying voice I've possibly ever heard. (I know, or think, that he's voiced by a woman, but that's not even the point). And to think that
| spoiler (highlight to read): |
| he's actually Ed and Al's older half brother (if he was human to begin with of course) |
just pisses me off.
And now for the World Champion of annoying anime characters, and this character defends the title night in and night out. People, I give you...
Shinji Ikari (Neon Genesis Evangelion):
We all know this kid is annoying like you know what and it seems like he was tailor made to be that way. Cries and whines every couple of seconds, is angry at his daddy but still yearns for his respect and more crying and crying and crying. I really like the kid and you can feel for him as well but we all have our limits and after a while you start wondering where this kid's manhood is and if he can ever stop crying. Damn, if I have the powers that rivaled God, I wouldn't be crying about it. Bitch.
Soory if its long and that's it for me.
Peace.
