The Mr. Plankton Universe is the unofficial name for an alternate universe where Plankton and Mr. Krabs' lives switched.



In this universe, Plankton became successful and Mr. Krabs did not.

Role in the series

In "The Algae's Always Greener," Karen suggests that he switch lives with Mr. Krabs. Plankton does so and enters a universe in which he is successful. However, he retains his memory from his previous life. In this universe, he learns that he runs the Krusty Krab and everything is the exact same except that he is the owner instead of Mr. Krabs and that Plankton is referred to as "Mr. Plankton". In addition, as Plankton later learns, Mr. Krabs goes by the name of "Krabs" and is in Plankton's role in Plankton's universe.


This section contains speculative information. This information has not been confirmed. Please keep this in mind.

An explanation of how this universe came to be can be explained by the events of "Friend or Foe."

In "Friend or Foe," it is revealed that Plankton and Mr. Krabs were friends from their birth to shortly after they started running a restaurant together. In the scene that broke their friendship up, Plankton and Mr. Krabs fight over the formula to their first patty. They both go flying and Plankton flies out the door and receives only one piece of the formula "chum". Mr. Krabs flies backwards and knocks down some ingredients and the Krabby Patty is born.

If Mr. Krabs and Plankton's positions are switched and Mr. Krabs flies out the door and Plankton makes the ingredients fly, this is when the universe begins. Plankton would abandon his girlfriend Karen to be more successful. He would have Pearl with the female that Mr. Krabs marries in the main universe. Krabs would pick up Karen and be less successful than Mr. Plankton. Mr. Plankton would hire Squidward, Jim, Not SpongeBob, and SpongeBob.

The only thing that is not explained however is why its still called, "The Krusty Krab" or why they are called, "Krabby Patties". It is possible that Mr. Plankton is less selfish than Plankton and would name both after his former friend, Krabs.
