Which character do you hate the most in Anime?

Haruhi Suzumiya. She's annoying and she basically sexually harasses Mikuru when she's not bullying her.

There is only one character I truly hate, The Celestial Dragons from One Piece.

The Nazis from Hellsing Ultimate. Honestly, what is their left to say. THEIR FREAKING NAZIS!!!

The Lobelia chicks from Ouran High School Host Club! There are few people I hate madami than them. >.<
And Orochimaru....

Aida Mana from Doki doki precure because she takes up all the spotlight

Haruhi Suzumiya - The Melancholy of Haruhi Suzumiya
Mai - Yugioh
Lucy - Elfen Lied

Does it count if I put everyone in the military police with the exception of Annie from Attack On Titan ...

I swear the military police give the scouting regiment a hard time on everything and act like their the best but when push comes to shove they only serve as titan fodder . Not to mention all they do is stay ligtas inside their little walls helping a corrupt government while the scouting regiments actually attempt to solve the titan issue in order to save humanity .

Single Character would be : Lenalee from D-Gray Man

Yuuka- Efen Lied
Konata Izumi- Lucky Star
They're both really annoying even though that I only watch a bit of Lucky Star, Konata Izumi annoys me the most. Yuuka is so annoying in Elfen Lied and the reason is that I really have to skip half of the whole anime series to get to the best part because Yuuka was like in every scene (not really that much). But I do hate Yuuka the most in anime.

There are probably so many madami characters I SHOULD hate more, but I have hated Tousen from Bleach so much for so long, it's pretty much a running joke.

He is always all about justice, preaching and pagganap all holier than thou, but then he went and stabbed his mga kaibigan in the back, even fighting his own mentor. In other words, the ultimate hypocrite.

Not to mention, his blindness is inconsistent in the show, like he's only blind when it's convenient.
