Sheldon J. Plankton

Karen is his robot wife, she is the thing he loves most in the entire universe; sometimes he neglects her a little and is always trying to impress her and seek her affection.

Friends: Karen (although she is also his wife)

Neutral: Squidward, Pearl, Ms. Puff, Patrick

Enemies: Mr. Krabs, SpongeBob, Sandy

From a young age, he felt alone, small, and vulnerable, so he created a robot named Karen to be his friend and later his wife. He had always dreamed of world domination and tried several times with Karen, all in vain, until one day he was told that with the secret Krabby Patty formula, he could rule Bikini Bottom. He opened a restaurant right in front of the Krusty Krab, declaring war on Mr. Krabs and beginning his attempts to steal the formula.

Egocentric, anger issues, not very affectionate (even with his wife), hates several people especially Mr. Krabs and SpongeBob, manipulative, very intelligent, needy of attention (especially from his wife) and conceited.

He uses his human appearance from the musical: Long black hair tied back, white skin, one eye with a red iris and the other white and blind and covered by a patch.
He wears a green suit, as well as green trousers and boots, which are intended to make him look taller and more imposing.
