Who is your most hated anime character/manga and why ?

Konata from Lucky Star. Agh I know she's such an iconic anime character and Lucky estrella is SUPER popular but I could never stand it, specifically her character. I think she's so whiny and such a stock character, who is supposed to be the main. Her character is just so lazily written and doesn't really have depth to her at all. I just really hate this anime in general (don't kill me) because I found it very boring and whiny. I personally enjoy animes that make tu think más and have más of a purpose o plot to them, so when tu get a mostrar like Lucky estrella I'm going to be put off por it completely. Especially when your lead character is just plain annoying.

Actually i hate Kageyama Ritsu from Mob psycho 100.
He's Mob's little brother. At first in liked him but later...
he's a terrible brother!! poor Mob, he's too much good and adorablee!( he's a baby who needs love!) He's allways looking for his brother but Ritsu is an idiot!! (if i say anything más maybe it's a spoiler, and i really recomend this anime to everybody so.. :D )

Though there are many annoying characters like Maka and whatnot, I'm just gonna go with one that I'll probably get hate for...
Light Yagami.
He started out with a good plan, sure, to rid the world of all crime and create a peaceful world. But, he let the power go to his head and let his pride nube his vision. It went from "creating a peaceful world" to "I will become god". He was selfish and prideful, and even put up a charade to be an innocent, kind person. He didn't seem to care about anyone at all, as he was barely phased por (Spoilers) L's o his father's death, and only used Misa and the other chick for his own needs of becoming god.
He was not a kind and forgiving person as a god ruling a peaceful world should be. If he had succeeded, he wouldn't become god. He would only rule as a mad king.
And even a god can die.
Anyways, yeah...I hate Light so much. >.>

Used to be the countess from Gilgamesh but is now Director from Kaiji, he's a sick individual, makes my skin crawl.

Its a tie between Tegiru from"Fushigi Yuugi:Genbu Kaiden"and Kanon from"Saint Seiya".Why I hate them?Because both of them are the shittiest brothers that tu could imagine.

Same answer as always from me, Zed from Kiba: TV Animation.
One día I'll find a character I hate more. Maverick from Tiger and Bunny came reeeeeally close, but considering Zed ruined whatever good there was in Kiba, he remains at the parte superior, arriba of my hate list.
The short version is he's boring, obnoxious, survives only because the plot protects him, never listens, and provides no good qualities except for ~*determination*~ which means absolutely nothing as just about every shonen MC does.

I'd say Shou Tucker

Everyone hates Kyubey:D This is lying evil alien with deceptive cute externality
