If you were looking for the article about the viking, then see Gordon.

Gordon[1] Plankton is the father of Sheldon J. Plankton, the husband of Mama Plankton, the paternal grandfather of Chip Plankton II, and the father-in-law of Karen Plankton.


Hooray for Dads!

Gordon looks like his son, except he is yellow-green, has a blue eye instead of a red one, wears an orange shirt with red flowers on it and has a brown mustache with a brown eyebrow.

A Plankton Family Tree

In the comic, he is deep green and looks almost jellyfish-like. He has light green eyes with red pupils and has gray hair and a gray mustache.


Gordon Plankton was born to Grand Dad Plankton and Lily Plankton. He had a brother, Silas Plankton.

He married Mama Plankton.

They had at least one son: Sheldon J. Plankton.

At some point, he obtained the job of an insurance salesman and tried to get his son to follow in his footsteps.[2]


  • He appeared in the storyboard for "Plankton Gets the Boot," where he and his wife refuse to let their son in after Karen kicks him. This scene wasn't featured in the actual episode.
  • He was completely unaware that Karen is his daughter-in-law.
