Top Ten Craziest Comic Book Villains

You thought the Joker's the only one insane? Well, here are these guys that are also crazy.
The Top Ten
1 Carnage Carnage (Cletus Kassidy) is a fictional supervillain appearing in American comic books published by Marvel Comics, usually as an enemy of Spider-Man. He appeared for the first time in The Amazing Spider-Man #361.

You thought Venom was bad, well, this symbiote with a psychotic serial killer went super-psychopath when he goes on a major killing spree. Spider-Man did have a hell of a time defeating this maniac.

2 Harley Quinn Harley Quinn is a fictional character appearing in American comic books published by DC Comics, commonly as a sidekick of the Joker.

She was good in Suicide Squad, but by far the best version of Harley Quinn is the Batman: TAS version, always cheerful but also a very tragic character.

"What's that? I should kill everyone and escape? Sorry, it's the voices," that should pretty much say everything.

"We're bad guys, it's what we do."

She's awesome!

3 The Joker 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. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for the Joker's design,... read more

He is the textbook definition of insanity. He kills thousands of people just for a laugh, and to break Batman psychologically.

4 Green Goblin

Goblin serum can mess up your mind, even the father and son of the Osborns have fallen into loose cannons after injecting the serum.

5 Negan Negan is a fictional character from the comic book series The Walking Dead and is portrayed by Jeffrey Dean Morgan in the American television series of the same name.

For the man with many F words coming out of his mouth, making sex jokes and having his barbed-wire baseball bat Lucille on his side, Negan doesn't keep things civilized for people, and he wants everything for himself. He even swung batta swing Glenn to death with his Lucille in the comics.

6 Purple Man

For this deviant purple dude, he did pull the nasty score big time when he mind-controls Jessica Jones for months to do psychological awful abuse, including controlling her to strip her clothes off.

7 Professor Pyg Professor Pyg is a fictional supervillain appearing in comic books published DC Comics, commonly as an adversary of the superhero Batman.

A sick bastard wearing a pig mask who loves to cut people up and torture them, but he's no match against Batman.

8 Hal Jordan (Parallax)

That time when Green Lantern Hal Jordan loses his mind after the destruction of Coast City and went nuts when he started killing his Green Lantern Corps pals.

9 Mad Hatter
10 Arcade

The last time I checked, this delusional sleuth tries to get teenage superheroes killed in the Avengers Arena story arc. It turned out to be the ruthless ways of survival in a place Arcade called "Murderworld". X-23 was among those teens, and it didn't go well for her thanks to this Jigsaw-Willy Wonka creep.

The Contenders
11 The Governor The Governor is a fictional character and a primary antagonist from the The Walking Dead comic book and television series.

Watching zombie heads in fish tanks, taking care of his zombie daughter, collecting zombies, killing his own people who failed on a job, and forcing people to fight each other surrounded by zombies for a game sport made the Governor this way.
