Plankton, full name Sheldon J. Plankton, is the main antagonist of SpongeBob SquarePants, the Nickelodeon animated series that premiered in 1999 and was created by Stephen Hillenburg. Voiced by Mr. Lawrence, the tiny owner of the Chum Bucket is obsessed with stealing the Krabby Patty secret formula from Mr. Krabs. His exaggerated evil laugh became a reusable meme clip on TikTok and soundboards, shared as a shorthand for mock villainy, petty plotting, and celebrating small wins as if they were world domination.
