Editing Karen

! colspan="2" | Karen's mobile form

'''Karen''' is one of the main characters in the series. She is the computer system of [[Sheldon J. Plankton]]'s laboratory, as well as his henchwoman, best friend and wife. She usually comes up with plans to steal the Krabby Patty secret formula, which Plankton tends to claim as his own ideas. She is voiced by [[Jill Talley]], an actress who is also the wife of SpongeBob's voice actor [[Tom Kenny]].

Karen was introduced in the episode [[Plankton! (Episode)|Plankton!]] along with her husband. She is one of the two main antagonists. As revealed in the episode [[Friend or Foe? (Episode)|Friend or Foe?]], Karen was just a security system when she started dating Sheldon. She has a Midwestern accent, in contrast to [[Sandy Cheeks|Sandy the Squirrel]]'s Southern accent and Plankton's Eastern accent.

In the [[The SpongeBob SquarePants Movie|first movie]], Karen informs Plankton of "Plan Z" by setting into motion the rest of the film's events. The movie also marks the first time Karen is seen in her mobile form; she is smaller and has wheels. [[Plankton]] also installed a button into Karen that would help him succeed in Plan Z and take over [[Bikini Bottom]]. In the [[The SpongeBob Movie: Sponge Out of Water|sequel]], she also plays a main role by powering the time machine that SpongeBob and Plankton use. She shares a heartfelt moment with Plankton when she is about to lose all of her power.

 

==Design/Changes==

She has a green wave on her screen to tell in which frequency she is speaking at. She has many buttons below the screen. [[Clem]] and the rest of [[Plankton's Cousins]] think that she is pretty. She has a built in analyzer, which can tell the ingredients in an item. In the majority of her appearances, Karen manifests as a large monitor in Plankton's lab or as her mobile, wheeled form. She is also installed into most of Plankton's inventions, such as Robot Krabs, Plankton's seashell submarine (as seen in [[It Came From Goo Lagoon (Episode)|It Came From Goo Lagoon]]), and the Chum Bucket's fist itself (as seen in [[20,000 Patties Under the Sea (Episode)|20,000 Patties Under the Sea]]). In the episode [[Goo Goo Gas (Episode)|Goo Goo Gas]], her baby face is shown as that of a calculator. As a baby, the only word she knows is "Hello". In "Welcome to Binary Bottom," she is a purple fish with a lab coat, black heels and hair and green glasses.
