Psy-Crow

Psy-Crow is one of the main villains of the Earthworm Jim series, and the archenemy of Jim.

Story
Psy-Crow is a intergalactic bounty hunter crow who has been a bad guy since forever. Psy-Crow is the main responsible for the birth of Earthworm Jim, because he accidentally dropped the ultra-high-tech-indestructible-super-space-cyber-suit while delivering it to his employer, the Queen Slug-For-A-Butt. The suit eventually felt on Earth, where Jim, who was just a common earthworm, entered it and mutated into what he is now. Psy-Crow was obviously tasked by the queen to retrieve the suit, chasing Jim around the galaxy, only to be beaten several times.

Jim eventually defeated the Queen, so Psy-Crow decided to kidnap the Princess What's-Her-Name, so he could marry her and become the new ruler of the galaxy. Jim goes after Psy-Crow to stop his evil plans, eventually saving the princess from his clutches. Some time later Jim goes into a coma after being bashed by a cow. Inside his own mind, Jim discovers that many villains are trashing his four brains, and Psy-Crow was one of them. Psy-Crow took residence into Jim's memory, fixating on a bad memory of the Great Farmyard War, instigating the duel between the cows and chickens. Jim manages to end the conflict and goes after Psy-Crow, defeating him and expelling him out of his mind.

In the cartoon series, Psy-Crow is shown to be a regular henchman of the Queen, often working together with Professor Monkey-For-A-Head. In one episode, both of them manages to overthrow the Queen, only to be dethroned shortly after by the Queen and Jim, who helped her just in this occasion.

Personality
Psy-Crow is nasty and psychotic. He loves blowing things and hurting innocent people without any real reason, just for the fun of it.
