Plankton

Plankton is a zooplankton that used to live in Bikini Bottom. (A place now in ruin because of the Fakegee Sea Creature War) After the war, he moved to a Universe in the Trolliverse that had lots of water covered planets. By the use of space age robots, he easily conquered 18 planets. These 18 planets seceded from that universe and was renamed by Plankton "The Empire of Planktopoli". Plankton has a history of evil. It all started when the Krusty Krab drove his resteraunt, the Chum Bucket almost out of buisiness. Plankton tried to steal the Krabby Patty Secret Formula until the war, where all of Bikini Bottom was turned into Fakegees except him. (He was too small for any Fakegee to find him) Today, Plankton is trying to conquer the entire Trolliverse by inventing robots. His current project is the Deathulizar Super Robotishinator Thingimabob (DSRT, often pronounced "Desert"). This project is very big in size. The robot will be able to fly through space at post-light speeds, shoot giant lasers, drop large bombs and send deadly gamma radiation.
