Behind the Scenes

This page is for Karen from ANY person's continuity!"

Karen Plankton is a main character in the original SpongeBob series who plays as Plankton's talking computer wife. She is revealed in many episodes that she is a Mac. She has a disliking for Plankton. Karen herself is actually a machine that can turn into any Mac - an invention of Plankton's. She is currently a Mac OS X Leopard. Karen once engaged in a conversation with Steve Jobs which was about which lawyers they would need to sue Bill Gates for selling recalled/error laptops. Karen is a high-tech 1986 computer that Plankton updated in 2009 so she would be more high-tech. In Konnichiku's series, she's a self-aware AI hologram that's friends with Swayzak. She also has a daughter in that series, named Caren.

Karen is also voiced by Tom Kenny's wife.
