Family

Plankton has a large, extended family,containing 10,000+ members of different forms of plankton, most of whom are supposedly from Texas and a character that people might consider hillbillies. It is from them that the audience learns his full name, Sheldon J. Plankton. He is also married to his super computer wife, Karen.

Robo-Plankton

In Spongebob Squarepants: Battle for Bikini Bottom, he tries to overtake The town by making Robots with his Duplicatron 5000. But backfires when he didn't set it to Obey. At the end of the game when the player defeats SpongeBot SquareShiftpants (the name in which he said in the episode Welcome to the Chum Bucket), a Robot portraying as Plankton (who is possibly smarter) on a little hovering machine with a small sonic ray gun comes out and tries to stop Spongebob from destroying his robot-self.
