She serves as the main antagonist of the episode, and it marks her only appearance in the series due to her destruction at the end of the episode by blowing up.
Karen 2 is more evil and also has a different design from the original Karen, it being made out of modern material. Unlike her, Karen 2 does not have arms although she used a utility arm to access the Chum Bucket power grid.
Role in episode
Karen 2 is destroyed by the original Karen at the end of the episode when she punches Karen 2 in the screen, because she ran over Plankton by accident, as she was not paying attention to where she was going.
She is "rebuilt" by SpongeBob taking the glass and electronics out of her screen and Mr. Krabs putting it on Squidward's face to help bring in more customers.
Karen 2 is called iKaren in Serbia.
This is a reference to Apple's "i" brands, such as iPhone.
