|List of characters|
Planktonamor Plankton is an ancestor of Plankton and is just as evil. He lived in a castle in a dark landscape on a somewhat of a hill, close to medieval Bikini Bottom. After kidnapping Princess Pearl he was found by SpongeBob, Patrick, Squidly and The Dark Knight and was almost victorious but was zapped by his own Dragon Jellyfish. He was the main antagonist of the episode Dunces and Dragons.
Planktonamor looks that he has old age considering having a white beard. He looks averagely the same as Plankton but he has a big purple cloak with a gold piece in the middle. He is still the same size as Plankton. His beady eye and antennae are also the same as Plankton's.
- "Dunces and Dragons" is the only appearance of Planktonamor and his wife, the Glass Ball Karen.
- He can use magic but it only tickles people.
- There are parallels to Lord of the Rings' characters Sauron and Saruman.
