Best Cartoon Network Villains

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?

With titles like "Deliverer of Darkness" and "Master of Masters" Aku is undoubtedly evil. Said to be nothing but pure evil he's ruled the world for thousands of years and enslaved countless peoples. He's even sent off captives to the Pit of Hate or to spend their lives in slave labor. he's an utterly foul being comprised of pure evil but despite that his ability to also provide comic relief makes him likeable.

Aku is the shadow of pure evil. No weapon can harm him, the only thing that can is the sword that posses the power of good and justice. If there was a battle between Aku and HIM, Aku would win with a palm of his hand and leave HIM in his own ashes.

HAIL AKU!

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.

He's brainiac in monkey skin.

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

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 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.

Watch "The whispers" now ask yourself why is lich not number one

Admin, we got ourselves the wrong Nergal here! - ModernSpongeBobSucks

That picture though

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

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.
