Best Cartoon Network Villains

The Top Ten

1 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.

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.

" Long ago in a distant land, I, Aku, the shape shifting master of darkness, unleashed an unspeakable evil. But a foolish samurai warrior wielding a magic sword stepped forth to oppose me. Before the final blow was struck, I tore open a portal in time, and flung him into the future where my evil is law. Now the fool seeks to return to the past and undo the future that is Aku."
Enough said

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.

2 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.

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.

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!

Hysterical monkey, Even though the Amoeba Boys are funnier. Is VERY evil too. I see the reason why the Gangreen Gang and the Amoeba Boys didn't make it to this top ten list.

3 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.

The most creepiest guy ever, He's definitely not like your average cartoon villain.

" If you join me, If you swear to serve me, If you never speak to your friends again... I will allow them to live. But, if you disobey even the smallest request... I will annihilate them, robin. And I'll make you watch. "
- Slade

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.

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

He's the definition of evil.

4 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" .

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.

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

I think he should be a bit lower He should be at #6

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

5 Father - Codename: Kids Next Door

Father is just ruthless. Watch his first appearance. Father is the first villain who ever defeated the KND and turned his children into animals.

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

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

He is underrated

6 Him - The Powerpuff Girls

I really think he was more powerful than any of the other villains. CN did a great job on him.

Him is number 1 definitely just watch tough love

Why is him not nunber two, he's a literate demon, mojo's just a smart ape

How is Mojo jojo above Him? Him is awesome!

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


This guy is so evil he makes children's souls turn into trees and then tricks a man into chopping them Down to grind them into oil to fuel his lamp which he tricks the man into thinking the lamp has his daughters soul! This thing is pure evil!

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.

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 (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 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.

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

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 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.

What about team rocket

12 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.

The best.Everything about him

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.

I hate the Kanker sisters!

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

14 Mandark - Dexter's Laboratory Susan "Mandark" Astronomanov is the main antagonist in the American animated series Dexter's Laboratory. 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.

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.

Good brain genius dexter is clearly more worse than mandark

Iconic and somewhat beguiling. One of the few true antagonists.

She's the best villain in the series

19 Ice King - Adventure Time The Ice King is a character in the American animated television series Adventure Time. 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.

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

Voiced by Tom Kenny and John Kassir in the pilot

20 Van Kleiss - Generator Rex

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

21 Garrett Bobby Ferguson - Regular Show

The role combined characteristics of the zanni and the Capitano. In the 2017 revival of the animated series Samurai Jack, Jack encounters a robotic assassin named Scaramouche, who behaves more.
