Post a fictional villain that you hate/dislike but acknowledge that he's/she's a great villain.

Light Yagami.
Goddamn do I hate his morals, his lying, just him in general.
But I have to admit...he started off with a good plan and he's smart as hell. He actually got pretty far...
Honestly I probably have a love/hate relationship towards this dude.

All villains are good villains. I like them all. Leave villains alone. Except Wormtail. Wormtail is a lil' weasel. And imo he isn't a good villain lol.

Ragyo Kiryuin.

I don't hate her but it's not that I particularly like her that much either. She made a great Villain in my opinion. Ruthless, Cruel, Sadistic and definitely not the best kind of Mother but also Prideful with an indomitable will. I believe she is pretty well-written !!!!

Bellatrix LeStrange from the Harry Potter series

I don't personally hate him.. But I kinda "respect" him..

RAY BURGARIN: (GTA 4)

He probably sseems a bit nice at first. Despite often making rather creepy comments, like the mention of gun fights give him a "bonor".

But than you remember. This is same man that caused Niko Bellic to move to Liberty City, out of fear of him.

You kinda wonder. How bad can he really be..

Ohh, he IS..

Ray's brutal murder of the cook, gives out a certain shock level. It's one of the few times (if ANY) that gta shows decapitated heads.. And it's seconds before Luiz gets surrounded by snipers. Merely surviving..

Nefera De Nile From Monster High (The sister to Cleo De Nile)

Souther from"Hokuto no Ken"
I hate him because he's a terrible human being who enslaved children and killed many people(including my favorite character and I might add that he did in the worst way possible)but I still think that he was a great villain that was hard to defeat and he had an impressive background story(that for a moment actually made me feel sorry for him)as well.All the fight between him and Kenshiro was one of the best fights of the entire series.

Slade/Deathstroke from Teen Titans. He was almost unbeatable.

He's not really a villian as the show goes on, but he starts off that way, and continues to be a tortured, selfish little brat who kills people when he can't get what he wants, although he does have a tremendous amount of heart. The show makes a point of that. Anyway, I love Damon Salvatore. I know the show is designed to make you be on the fence about him, "is he good, is he bad, does he deserve such a crappy life, blah blah blah", but most villians I 'like', I don't /really/ like. I like him. Like, if he were a real person in front of me right now, I'd give him the biggest hug.

Dolores Umbridge. I absolutely hate this character with a passion, but I will say that she is a great villain and a fantastic example of a malevolent bigot who uses deception and oppression to get to the top. And Imelda Staunton does an amazing job at playing Umbridge, I don't think any other actress could've made her as fun to hate as she does, especially because Umbridge is a character the reader is supposed to hate.
