1 The Lich - Adventure Time
The Lich (formerly named the Lich King in the original pitch and "His Hero," and referred to as Sweet Pig Trunks in his baby form, or just Sweet P for short) is a powerful undead being and a major antagonist in the American animated series Adventure Time.
Ok, he's really creepy guy. I mean just look at him. Also he's kinda untipical villain who whants to murder a few people or take over some territory. The Lich wants to destroy any life, nothing more, nothing less. Master manipulator, extremely powerful, dark, scary, sadistic almost unstoppable and purely evil. Easily one of the best modern villains
Unlike other villains who either wants to take over the world or the universe. The lich wants to end everything created.
He has no soul. His only purpose in his life is to end all life on Earth. What's more evil than that?

3 Bill Cipher - Gravity Falls
Bill Cipher is a triangular dream demon formerly existent only in the mindscape who wished to gain access to the real world. He has been running amok in Gravity Falls, Oregon since being summoned by Stanford Pines over thirty years ago. He is known for his mysterious demeanor and sadistic humor. He is the main antagonist of Gravity Falls, although he doesn't play a central role in the series until season 2.
He's got the best everything, personality, laugh, voice, design, power, motive, and even death. He will be remembered as the best TV villain in history.
He is terrifying, but lovable. If you were a random person who didn't know anything about this cute looking character, he is a definite wolf in sheeps clothing. At the first episode that he comes in, Dreamscapers, he will charm you with his humor and basic awesomeness. But as the show goes on, the more drawn you get. This one character has the same spell as fnaf, once you come inside the fandom, you can't get out. Now why you may be sitting here reading or skipping past this, thinking, why are these people so terrified of a dorito dollar bill chip like creature?! Watch Dreamscapers, Sock Opera, Mabel and Dipper VS the Future, and then, you might be ready for the three episodes of Weirdmaggedon, which come right after Mabel and Dipper VS the Future. Although, you probably won't understand the plot, at least you will get a good idea of how Bill Cipher is truely, a character we hate to love. The single idea of him getting into my head sends me shivers down my spine.
Bill is horrifying. He can slip into your mind and control you and he slowly gets closer to his goal of taken over and destroying our universe like he did to his!
I personally think he's the greattest villain in any fiction ever
He is an absolute BEAST in Gravity Falls. Also, his voice is amazing and I want it...
