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.

He is so powerful and tough to defeat. It took Jack 50 years to get to the past. Jack suffered for 50 years

Because, this is the main villain of samurai jack

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.
3 Plankton - Spongebob Squarepants Plankton - Spongebob Squarepants Sheldon James Plankton, or simply Plankton, is a character in the Nickelodeon animated television series SpongeBob SquarePants.

Even though he has been bogged down in the newer seasons, if you look back at the original 3, and I'll even say season 4, he was pretty mean and really funny. Take the first movie into account, and he truly is a terrifying villain.

4 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 ...read more.

Probably one of the first cartoon- anime influenced shows I watched. I always remembered how evil and vengeful Slade was and still is. He puts up more of a fight then the other villains on Teen Titans. Half of his dialogue is memorable enough said.

Wait until TTG ruins him - TwilightKitsune

I love Slade

38 Foop - Fairly Odd Parents Foop - Fairly Odd Parents

I don't care what anybody thinks about Foop. To me, he's one of the best modern-season villains on the show. - ModernSpongeBobSucks

Yeah, you do have a point there. I guess the writers thought Foop was more clever and decided to ditch Anti-Cosmo for him. Then again, The Fairly OddParents has been ditching a lot of old characters for new ones, which isn't really helping the seasonal rot it's going through... - ModernSpongeBobSucks

He reminds me of Stewie Griffin, lol. That attitude and his voice...
