Best Cartoon Network Villains


The Top Ten

1 Aku - Samurai Jack Aku - Samurai Jack Aku is a fictional character and the main antagonist of Samurai Jack, an American animated television series created by Genndy Tartakovsky for Cartoon Network.

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?

2 Mojo Jojo - The Powerpuff Girls Mojo Jojo - The Powerpuff Girls Mojo Jojo is a fictional character from the American animated television series, The Powerpuff Girls, created by animator Craig McCracken for Cartoon Network.

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.

3 Slade - Teen Titans Slade - Teen Titans Slade is a fictional incarnation of the character Deathstroke in the American animated series Teen Titans and is the archenemy of the Teen Titans, who wants them destroyed for his own unknown reasons, and is the main antagonist of Season 1 and Season 2; He appears as a vision in Season 3, returned only more.

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

4 Katz - Courage the Cowardly Dog Katz - Courage the Cowardly Dog Katz is a fictional character from the Cartoon Network animated series, Courage the Cowardly Dog. He frequently appears as a recurring antagonist in the series . His first appearance was in the episode "A Night at the Katz Motel" .

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.

S o p h I s t I c a t I o n

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

5 Father - Codename: Kids Next Door

He is just so evil.

He is the greatest villain that the kids next door ever had to face

He is underrated

This guy is mean and ruthless and after him my number 2 would be Him form the Powerpuff Girls

6 Him - The Powerpuff Girls

Voiced by Tom Kane - 445956

Him is number 1 definitely just watch tough love

How is Mojo jojo above Him? Him is awesome!

Needs to be number one!

7 The Beast - Over the Garden Wall

"Good" villains have some sort of redeeming quality or perhaps some reasoning behind their actions.
There's a purpose behind their villainous deeds, so while the actions of the villain are... villainous, their INTENTIONS are good (at least at first).

Some classic examples:

Darth Vader = goes to the Dark Side... to try to save his wife.
Lex Luthor = is a sociopath and a psychopath... but he honestly thinks everything he does is for the greater good.
The Illusive Man = xenophobic (to an extreme) and hinders Commander Shepard... all in a bid to save humanity from extinction and ensure humanity's progress in the galaxy.

So while we know they're the bad guys, we can find a grain of heroism in who they are.
Not so with The Beast.
He is only thinking of himself, he has no grand plans, and he DOES NOT CARE how his actions affect others.

He is unfettered, unprincipled, and apathetic unless it concerns his own well-being.
The only villain to come ...more

One of the most mysterious, cunning and messed up villains I've ever seen. He trully has a place in a grim dark show like Over the Garden Wall and definitely should be higher on this list.

Very sinister. He traps children's souls in trees, for cry it out loud!

How is The Beast so low! In my top ten Cartoon Network/ Disney Cartoon villains he was number 6!

8 The Lich - Adventure Time 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.

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.

9 Nergal - The Grim Adventures of Bill & Mandy Nergal - The Grim Adventures of Bill & Mandy Adam Nergal Darski (born Adam Michał Darski; 10 June 1977 in Gdynia), is a Polish musician and television personality, best known for being the frontman for the black/death metal band Behemoth. more.

He is a great guitarist yeah

That picture though

10 X.A.N.A. - Code Lyoko

Voiced by David Gasman - 445956

While I agree with the idea that aku is the most well known except for possibly slade, xana was a better villain than ALL of them.
His Suttle manipulations are more interesting then the typical world domination archetype.
He was also relentless and didn't let his enemies live, as he was the only one on this list who actually killed someone, in XANA's case, Franz Hopper

The Contenders

11 Mewtwo - Pokemon Mewtwo - Pokemon Mewtwo is a fictional creature from Nintendo and Game Freak's Pokémon media franchise. It was created by Dr. Fuji in an attempt to clone Mew.

12 Vilgax - Ben 10 Series Vilgax - Ben 10 Series Vilgax is a fictional character and one of the main antagonists of the American animated TV series and media franchise Ben 10 created by Man of Action Studios and produced by Cartoon Network Studios.

Voiced by Steve Blum, James Remar, and Yuri Lowenthal - 445956

13 The Kanker Sisters - Ed, Edd n Eddy

They're not villains per se but they definitely harass the Eds to the point that they can be scary. - Daviddv0601

I think that the Kanker sisters are the best Cartoon Network villain because unlike other villains, who want to take over the world and fail, they are successful when it comes to their goal, torturing the other children of the Cul De Sac - TelevisionGamer

I hate the Kanker sisters!

14 The Joker - The Batman The Joker - The Batman The Joker is a fictional super villain created by Bill Finger, Bob Kane, and Jerry Robinson who first appeared in the debut issue of the comic book Batman (April 25, 1940) published by DC Comics.

He is Dexter's rival and later mortal nemesis who often seeks to destroy both Dexter and his lab to prove once and for all that he is the superior genius. He is voiced by Eddie Deezen.

19 Van Kleiss - Generator Rex Van Kleiss - Generator Rex

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

A supposedly evil wizard capable of creating and manipulating ice and snow, he is the self-proclaimed king of the Ice Kingdom, a land of ice he claimed as his own and lives in in company of many penguins.

29 Tom - Tom and Jerry Tom - Tom and Jerry Thomas "Tom" Cat is a fictional character and one of the title characters in Metro-Goldwyn-Mayer's series of Tom and Jerry theatrical cartoon short films.

Tom is not a villain.

He's not a villain. - SuperBananagengar

30 Rowdyruff Boys - Powerpuff Girls

Voiced by Rob Paulsen and Roger L. Jackson - 445956

31 Aquamarine - Steven Universe Aquamarine - Steven Universe

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.

Voiced by Della Saba - 445956

So evil

32 Rob/Dr. Wreckor - the Amazing World of Gumball

He's just awesome, the greatest character in this entire series!

The only episode you need to see to be convinced is the ending for season 4 and begginner for season 5 - SuperBananagengar
