Alternate-Universe Patrick
Alternate-Universe Patrick appears in "Roller Cowards" and "Rule of Dumb" In "Roller Cowards," AU-Patrick called Patrick a "Big fat crybaby." Patrick responded by punching him and saying 'I thought we settled this the last time!," meaning him and Patrick encountered each-other before. In "Rule of Dumb," AU-Patrick looks like Patrick, but with an evil expression and deeper voice. Patrick and AU-Patrick can only see each other using a mirror. They can reach into each other’s worlds (Proven by Patrick, when he punches AU-Patrick.) Patrick and AU-Patrick don't like each other very much. He also supposedly appeared in "The Great Patty Caper" when Patrick suggests that
his reflection in the window looks suspicious. Afterwards, the reflection gains a smug expression, then walks away.
His most recent appearance was in a unnamed SpongeBob comic in the Nick Magazine September 2009 issue. In the comic, SpongeBob and Patrick receive a treasure map from an elderly sailor. SpongeBob reminds Patrick of the curse that the sailor told them off. When SpongeBob then tells him about what the sailor said, a bubble comes up with Alternate-Universe SpongeBob , Alternate-Universe Patrick and Alternate-Universe Elderly Sailor reenacting when the sailor giving the map to them. When Patrick denies that even happened, the Alternate-Universe Sailor slaps him and says "Sure I did! Pay attention, sonny!" Then, in the background, Alternate-Universe Patrick is laughing at him and Alternate-Universe SpongeBob is staring at SpongeBob with a blank expression.
