Worst Cartoon Network Villains

The Top Ten
1 Badcat - The Problem Solverz

It's the Problem Solverz, of course it is bad. (Voiced by Mark Hamill)

2 Toiletnator - Codename: Kids Next Door

He's so bad yet so funny and that makes him my second favorite villain from Kids Next Door after Father

A toilet, seriously? (Voiced by Dee Bradley Baker, and Quinton Flynn in some random CN game)

3 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.

He's pretty much a hero, and when he was a villain, he was a pathetic one. (Voiced by John Kassir in the pilot, Tom Kenny in the series)

Discord rules, Ice King drools.

4 The Amoeba Boys - The Powerpuff Girls

Boring tiny villains. (Voiced by Chuck McCann)

5 The Earl of Lemongrab - Adventure Time

He's a funny character but a stupid villain. (Voiced by Justin Roiland)

6 Control Freak - Teen Titans Go!

He was already the worst part about the good animated series, and TTG actually managed to make him more annoying. (Voiced by Alexander Polinsky)

7 Sunny - Ben 10: Ultimate Alien

I liked the series, but this character is an annoying Blackfire rip-off. (Voiced by Ashley Johnson)

8 Simian - Ben 10 Franchise
9 Pandora - The Grim Adventures of Billy & Mandy

One of my favorite hows parodying Dora the Explorer. GREAT. (Voiced by Nika Futterman)

10 Princess Bubblegum - Adventure Time Princess Bonnibel Bubblegum of the Candy Kingdom is a fictional character in the Adventure Time animated series on the Cartoon Network.
The Contenders
11 Stickybeard - Codename: Kids Next Door

Better than Toiletnator but still is a bad villain. (Voiced by Mark Hamill)

12 Beast - Over the Garden Wall
13 Pumyra - ThunderCats (2011)
14 Grune - Thundercats (2011)
