Best Cartoon Network Villains

So over-the-top! He is fun to watch. Can be a comedic villain in one episode, and a pure evil nightmare in another! - Daviddv0601

Evil incarnated dark and wonderful voice

The only villain ever that could defeat Aku is bill cipher, and he's not on Cartoon network...

He fought the old gods and nearly ruled the Universe. After his initial defeat, he landed on Earth and proceeded to kill humans for centuries before he conquered the planet. He sent the only man who could stop him, Jack (after enslaving his people), into the future to witness what centuries of suffering looks like under his rule. He has unlimited power, strength, and knowledge, yet still gets pleasure from seeing others, especially Jack, fail. Did I mention is literally the physical manifestation of Evil? Black, takes all shapes and sizes, and he shoots laser beams from his fiery eyes. Is this even a competition?

He is so much fun! I wish - Daviddv0601

Mojo Jojo is all I like an archenemy to be. Menacing, Badass, intelligent, wise, cunning, mysterious, dominant, misanthropic, funny, competent and sophisticated. He's got eyes of revenge, against the Powerpuff Girls, and would do anything to stop them.

Another trait I like about Mojo Jojo is that he also uses good manners, even around the people he hates (unless they get to piss him off).

He is very diabolical and quite evil indeed. Clearly by the evidence shown in his evil objectives and evil actions he is quite a BAD MONKEY and is VERY EVIL!

Mojo yearns just to be evil. And as a "thorn in the City of Townsville" side he's in, Mojo is more severely thwarted, bested and embarassed by his hero counterpart. Lest we forget, his hero counterpart is a trio of preschoolers. Mojo Jojo is Craig McCracken's love letter to super villains, and we see that echoes in many of the schemes that Mojo's pulled, from gathering all the baddies to form a league of supervillains, to reverse-engineering the Powerpuff DNA, and making evil twins for the girls. It is Mojo's belief in being evil, that makes him such an awesome villain.

Easily my favourite version of Deathstroke. He is ruthless, manipulative and absolutely deranged. - Daviddv0601

Evil. This villain is the embodiment of evil. He has alluded the Teen titans for so long I don't think they can touch him. Evil to the core without one regret. Slade deserves to be the number one Cartoon Network villIn.

He's the definition of evil. - PeeledBanana

Suave, psychotic, evil. What's not to love? - Daviddv0601

Smooth, suave, and evil. Plus he has the best theme song by far of any villain.

Seriously, this villain was absolutely awesome and badass, so sleek, a sleeker villain won't exist in cartoon network history at least.

The Lich, simply put, is the twisted manifestation of the raw lack of existence that originated before nothingness itself. He is not an agent of death, but the End incarnate. He is not merciless; he simply knows not mercy. Upon examining the Lich from an non-subjective standpoint, the utter fear and hopelessness it induces on those that stand in its gruesome path forces the primary protagonists to undergo some of the most strenuous character development ever portrayed on an animated series, even leading the audience to challenge their own perception of reality. Whilst it is a shame that the Beast has not attained a higher position on this list, I firmly believe that the Lich ought to be considered to be the most vicious and unrelenting antagonist to have ever graced the face of modern television, or, at the very least, the "Best Villain" ever conceived by Cartoon Network.

The Lich is extinction incarnate. He does not want money, power, or too play mind games with the hero. He has one goal too end all life everywhere in any form. You can not stop him, you can only temporarily subdue him until he comes back and every time he comes back he's all the more dangerous.

Truly the most incredible villain I have seen in any cartoon. I looked up this page just to see his name at the top. I'm incredibly surprised that it isn't already. Composed of pure evil, created only to end all life in the universe, he's more than just your typical world-domination madman.

Epic villain. A true force of serious, sincere, pure evil who will stop at nothing to destroy the world. A better villain than the Ice King.

He is a great guitarist yeah

Namely going off of Ego Trip, but Mandark stole Dexter's idea's, banned all technology, and was blown up only leaving his brain behind. Of course there is also his laugh.

Should be 2

Voiced by Troy Baker - 445956

He is the best villain in any cartoon series ever with Amon and the Beast being close second and third. His mysterious past, cunning, and the fact that he is voiced by Troy Baker make him all the more amazing. It is dissappointing more people have not seen this awesome show.

He has the best villain theme in all CN

Man this guy really wants an ice queen so obviously he was a nice man before a nuclear war the destroyed the war.

Peridot is a crystal gem not villain anymore but still funny! 😉👍👍

Tom is not a villain.

He's not a villain. - SuperBananagengar

Honestly a better villain than the diamonds. They fight the protagonists to further their strict empire, and other antagonists such as Eyeball or Jasper fight to avenge what they, at the time, believed was the death of Pink Diamond.

Aquamarine, however, even though she is serving Homeworld I doing so, seems to be so cruel because she enjoys it, and even takes joy out of abusing her companions, Topaz and Topaz.

She is more sadistic, cruel, selfish, and angering than any other character (let's put Rose Quartz aside for now) that we've seen on the show.

I'd definitely call her the best antagonist of Steven Universe, and she deserves at least top 15.
