Karen Plankton is a female computer and the wife of Plankton. Both of them live in the Chum Bucket. Karen is one of the major antagonists of the SpongeBob SquarePants franchise and often assists Plankton in his schemes to steal the Krabby Patty secret formula, most of which are unsuccessful. Both characters first appear in the episode "Plankton!". Karen is voiced by Jill Talley.
Karen is a blue computer monitor with a black screen which can only display neon green visuals. A waving line is usually shown on Karen's screen, and it moves whenever she talks. Karen takes on the form of either a wide monitor, which is attached to a wall in the Chum Bucket, or as a wheeled computer.
