Giant Plankton is an alternate universe version of Sheldon J. Plankton, who is from a universe where he is big. He may be from the same universe as Small Mr. Krabs, Small SpongeBob, and Small Patrick.


He looks exactly like Plankton, but he is scaled up significantly.

It is important to note that he is not as big as Giant Dream Plankton.


He appears at the end slapping his head after SpongeBob realizes that Super SpongeBob SquarePants is the superhero of Bikini Bottom 2.
