The Top Ten

1 Tywin Lannister Tywin Lannister is a fictional character in the epic fantasy series A Song of Ice and Fire by American novelist George R. R. Martin.
2 King Joffrey Baratheon

Oh my god he is incredible. He flawed, funny, repulsive as all get out, dangerous when he wishes, but he actually has some depth and arcs going on. Where do I even begin with his atrocities?! It's too numerous and you really need to see it. It is so memorable that he is one of the only kids you would happily cheer for dying horribly. He is THAT nasty.
Saving myself an essay of atrocities, he does endure some humiliating and well deserved putdowns that make us enjoy watching him, Tyrian slapping his ass, Sansa and Cersei slapping him, Arya emasculating him, angry peasants throwing a cow pie at him. He is a wonderful actor too, and very much a spoiled rotten cowardly teenage king that I love to hate.
He's also got some very small moments; he sincerely loves King Robert, and is happy with his name Baratheon, even though his is a true Lannister, due to being a product of incest. Being a teenager, he is prone to vicious and stupid actions that gets lots of people kill, but in the ...more

3 Littlefinger

The man who started the war, who caused chaos for his own needs. He back stabbed everyone to climb from a lowborn position to lord of the vale. He also killed King Joffrey, due to his displeasure and own goals.
Whatever his mysterious goals are, it's quite a journey for him, and his counterpart, Varys, is concerned about him.
He's got a personal connection with the starks, Caitlyn, Ned, and Sansa Stark, which does make him both human and vile, and is willing to share his accomplishments with Sansa because of his unrequited love for Caitlyn.
He's still around for season 7, but he's finally hitting some serious roadblocks, which is good, because a great villain defeat is anticipated.

4 Gregor The Mountain Clegane Ser Gregor Clegane, nicknamed The Mountain, is a fictional character in the A Song of Ice and Fire series of fantasy novels by American author George R. R. Martin, and its television adaptation Game of Thrones.

The meanest, scariest warrior in the series. Every badass warrior in the series is rightfully terrified by The Mountain that Rides. He is also the most censored villain in a series that makes torture porns look tame. Let that sink in.
He isn't completely one dimensional either; because of his freakish size, it realistically causes him pain and headaches, and the reason why he is so violent and angry. He burned Sandro Clegane's face as a kid, and yet, he was favored by his pop, and knighted by prince rhaegar. They ended up dead as thanks. He destroyed Sandor's idealistic viewpoint on knights, and everything in Tywin Lannister's path. He likes to hurt and kill people.
He also is a serial rapist; we never see that until the very implied fate of septa unella.
It's why obern martell wanted to kill him. Gregor was poisoned, but thanks to Qyburn, whom gregor almost killed in the past, saved him and made him stronger, and is cersei's silent but very deadly champion. I look forward to ...more

5 Qyburn

Of all the minor villains, Qyburn is the ace in the hole for Cersei Lannister's sidekick. Without him, cersei wouldn't be queen, and without him, we wouldn't have Zombie Mountain or Queen Cersei.
Pycelle, who only survived as long as he did by being an ass kissing toad, finally met his end thanks to qyburn.
Qyburn also has an interesting philosophy; true he got expelled for his very cruel experiments, but they yield good results, because he is legitimately making new discoveries instead of passing along old knowledge. A very dangerous but interesting character.

6 Cersei Lannister Cersei Lannister is a fictional character created by American author George R. R. Martin. She is a prominent point of view character in Martin's award-winning A Song of Ice and Fire series, and also a main character in HBO's adaptation of the series, Game of Thrones.

She would be rated higher if she wasn't so flawed with severe incompetence, and lack of true cunning.
But she remains high because of her personal faults, her roles in effectively starting the war, her personality and actions, her few redeaming qualities, and her memorable wrath.
Cersei at her very best is when she has her victims cornered, and delivers disproportionately cruel fates, look what happened to Septa Unella and the remaining Sand Snakes. You don't want to push this bitch around too much, or she'll get you like she got her husband King Robert, the High Sparrow, Margeary Tyrell, even to her eyes, disloyal Lannister relatives.
Her being queen regent, and recently, first queen, puts her in a dangerous position to enact her revenge. And her acting is a sight to behold.

7 Melisandre

Very much a mystery, one of the few magical beings, but also Stannis Baratheon's enabler.
A little girl was burned alive because of her devotion to her god.

8 Euron Greyjoy

I thought he was a total joke, as well as the house of Greyjoy, but he gets on this list in season 7 for proving me wrong. Two houses defeated in one fell sweep. Cersei is lucky to have him.

He's also quite audacious, taking several jabs at Jaime Lannister, while also providing some charm to Cersei. In battle, he's quite threatening, while also killing two of the most hated characters in the show, with their own weapons no less. Gotta mention in the books, he was pretty overpowered.

9 Roose Bolton

He's way better in the books, and was killed off too quickly and unbelievably, But he does uphold the principles of simply the most evil house in game of thrones. But he is an intelligent and pragmatic monster.
What brings him higher than Ramsey, apart from birthing him, is his participation in the red wedding. The Freys are insignificant enemies or even allies throughout, but Roose Bolton was supporting the north for a time, despite his really savage methods, and his betrayal hurt, and breaking sacred tradition willingly. Throwing his hat with the Lannisters.

10 Ramsey Bolton

As far as one dimensional monsters goes, he is by far the vilest, absolutely broke Theon Greyjoy, and is one of the only ones worth mentioning. He's the lowest on the list for his supposed flaws not really hindering him, and being the only memorable villain of the north in season 6 due to a lack of good and memorable villains
