Artemisia of 300: Rise of an Empire. From "Is Just Mad Greek Weather" to "I'm Not Here to Be a Witness" to "You Fight Harder than You Fuck". Is The Villain I Want Against Me or Better Yet, Don't Mind Fighting by Her Side, I will be as Evil as She Wants Me to Be. Eva Green.

Lex Luther, much like Trump.

Yzma from The Emperor's New Groove.

do the flying monkeys on the Wizard of Oz count?

Look out Bullwinkle!!

Catwoman from the old batman

Cthulhu. No question.

The greatest (and sickest) vanity plate I ever heard of:

Seth

Good 'Ol Satan...he only killed ten people in the bible...if you don't count collateral deaths of slaves (servants).

Macbeth. In many good stories the hero starts out vulnerable and grows wiser, stronger, and more virtuous as the story progresses. It is the opposite in Macbeth. He starts out as a loyal soldier for his King and devolves into a villain with no qualms about murdering anyone who gets in his way.

The Joker on the (dark night). Movie of Batman.

Snydly Whiplash..

God

Wile E. Coyote.

Mojo Dojo from the Powerpuff Girls.

Yahweh, for mass genocide, ethnic cleansing, and the near obliteration of the human race, yet maintaining a loyal following. That's some true wickedness right there.

Okay, serious answer: I'm drawn to villains that are flawed but not in a cartoonish way. I like them to be people with hopes and dreams, but who have something deeply wrong with them. Perhaps their horrific acts are the result of blind anger or a mental imbalance or even a philosophical perspective that, if you try a little, you can empathize with. But I think there also needs to be something truly frightening about them, something unpredictable or an amoral aspect that leaves you feeling uneasy about what they could do at any moment.

I prefer a villain like Magneto from the X-Men franchise, because, though he's the enemy, you totally understand where he's coming from and why he feels the way he does. He's not evil, per se, but he is willing to do whatever he thinks is necessary to bring about the world he envisions for the survival of mutants everywhere.

Anakin Skywalker. All he ever wanted was to save Padme and gain immortality.

I have to agree with others here who like Heath Ledger's portrayal of the Joker. His is the darkest, most layered version of the villain. It has no camp at all, unlike Nicholson's, who was a good baddie, but still patterned after the Cesar Romero version from the original Batman TV series, right down to the cackle. LOL! Also agree with others here that Ledger's loss was huge.

I don't know much about the character, but I suppose Thanos will make my list after I see Avengers: Infinity War. He's supposedly one of the top most powerful villains ever.

All of them are either powerful, creepy, diabolical, quirky, assholish, or evil lol. Makes for good entertainment.

I have always loved Twoface. He is one who plays his life based on flip of a coin.

In recent memory it would still be Guanter O'Dimm from Hearts of Stone.

He is for intents and purposes the devil, and the necessary evil in the world he inhabits. He plays up your classic Faustian devil tropes, granting people what they wish and not what they want. Weaving word traps and contracts to collect peoples souls, reveling in the tough choices. A friendly and yet eerie demeanor that always has one on their toes when interacting with him. He goes by many names: Master Mirror, The man of glass, a seemingly humble merchant selling his services to those in need. His influence is felt throughout all lands, and he is not above making a lesson out of those who have not only wronged him, but live out lives of vice. One may argue that those he deals with are the evil ones, but it is also fair to assume that he brings out the evil within mens hearts.

I can't forget Yoshikage Kira either, another seemingly normal man who is in reality a horrifyingly disturbed individual. All he wants to do is live a quiet and normal life, unnoticed and in the background doing his normal office job, and being a gentleman. A shame that he's some fucked up serial killer with a uh..."hand fetish", and the ability to turn whatever he touches into a bomb essentially, able to destroy any evidence or anyone. He sees his serial killing as a "bad habit", like drinking. Polite, professional, and calm, but on a whim has turned into a brutal monster when backed into a corner.

I love Jane from the Twilight saga. The book was better than the movie.

Sauron and Saruman with a big honorable mention to Darth Vader

Javier Bardem as Anton Chigurh, the hitman in No Country for Old Men.
