Top 10 Most Evil Cartoon Villains

Cartoon villains have a way of getting under your skin. They're not just characters on a screen. They're the ones who make you clench your fists in frustration, feel a chill down your spine, or question how anyone could come up with someone so sinister. The most evil cartoon villains don't just scheme. They embody the kind of darkness that defines their shows and keeps you hooked.

They are often the driving force behind the action, drama, and sometimes even the humor.

The Top Ten

The Lich - Adventure Time

The Lich, originally named the Lich King in early concepts and the episode "His Hero," is a powerful undead entity and a major antagonist in the American animated television series Adventure Time. In his infant form, he is referred to as Sweet Pig Trunks or Sweet P. The character represents pure evil... read more

Okay, he's a really creepy guy. I mean, just look at him. Also, he's a somewhat atypical villain who wants to murder a few people or take over some territory. The Lich wants to destroy any form of life, nothing more, nothing less. A master manipulator, extremely powerful, dark, scary, sadistic, almost unstoppable, and purely evil. Easily one of the best modern villains.

Unlike other villains who either want to take over the world or the universe, The Lich wants to end everything created.

He has no soul. His only purpose in life is to end all life on Earth. What's more evil than that?
Frieza - Dragon Ball Z

Frieza is a fictional character in the Dragon Ball series created by Akira Toriyama. He is the main antagonist of the Frieza Saga and is known as a tyrannical ruler of the Frieza Force.

Frieza is the most evil character ever! Twice as evil as the evilest! He would kill a child with no mercy!
Bill Cipher - Gravity Falls

Bill Cipher is a triangular dream demon featured in the animated television series Gravity Falls. Originally confined to the mindscape, he was brought into the real world after being summoned by Stanford Pines over thirty years ago.... read more

He is terrifying, yet lovable. If you were a random person who knew nothing about this cute-looking character, he is a definite wolf in sheep's clothing. From the first episode he appears in, Dreamscapers, he will charm you with his humor and basic awesomeness. But as the show progresses, the more drawn you become. This one character casts the same spell as FNAF. Once you enter the fandom, you can't get out.
Now, 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 Weirdmageddon, 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 truly a character we hate to love. The mere idea of him getting into my head sends shivers down my spine.
