445956
Not the most evil ones, but the ones who are just plain bad.

The Top Ten

1 Blargetha

Slime Princess's scammy sister whose evil was just mediocre. (Voiced by Katie Crown) - 445956

2 Ash

This guy literally defines "jerk." (voiced by Steve Agee) - 445956

3 Ricardio

Just straight up creepy. (Voiced by George Takei) - 445956

4 Ice King Ice King 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.

So pathetic they made him a hero a few seasons in. (Voiced by Tom Kenny) - 445956

5 Martin Mertens

If this guy was my dad, I'd run to an adoption center. (Voiced by Stephen Root) - 445956

6 Sir Slicer

This guy was mostly just a bully disguised as a powerful knight. 9Voiced by Peter Stormare) - 445956

7 Tree Witch

If she was more of an actual villain I would put her higher. (Voiced by Thurop Van Orman) - 445956

8 The Fool

The worst of the Stakes villains. (Voiced by Ron Funches) - 445956

9 Gareth

His design is creepy. (Voiced by Sam Marin) - 445956

10 Marceline the Vampire Queen Marceline the Vampire Queen

She is a vampire, hence here name. I know there's lots of you, vampire fans, but she, in my opinion is the worst character of the series because she is a vampire like I said earlier. Vampires are said to be pure evil blood-sucking immortal creatures of the night. >:( - (voiced by Olivia Olson) - DinoLover4242

The Contenders

11 Tiffany Oiler

Dumb brat. (Voiced by Vincenzo Rauso/Collin Dean) - 445956
