what is plankton from spongebob

Plankton is a character from the animated television show "SpongeBob SquarePants". He is a pint-sized microbe with an evil plan to steal the Krusty Krabs secret Krabby Patty recipe. Plankton is egotistical, aggressive, and power-hungry, and he is very jealous of Mr. Krabs and his success. His only goal throughout the series is stealing the Krabby Patty recipe. While the main antagonist of the SpongeBob SquarePants series is typically referred to as Plankton, the planktonic character we're talking about falls into the zooplankton category and is specifically most likely a copepod.
