Sheldon J. Plankton (simply known as Plankton) is the main antagonist of the Nickelodeon animated series SpongeBob SquarePants. A one-eyed planktonic copepod (hence his surname and nickname), he owns and operates the Chum Bucket restaurant, along with his wife Karen, where he also resides. Due to his restaurant's failure, his main goal throughout the series is to steal the Krabby Patty secret formula from the Krusty Krab, an across-the-street restaurant owned by Plankton's arch-rival Eugene H. Krabs.

History[]

Plankton and Mr. Krabs were great friends when they were young. They created the Krabby Patty together after the most popular burger joint got shut-down. After everyone had a patty it made their stomachs ache and cramp. After they made enough money they got in a fight and each got half of the recipe. Mr. Krabs got the half that had everything on it but the ingredient that made everyones stomachs ache. That ingredient was chum. So ever since then Plankton has been trying to steal the recipe.
