List of characters
Planktonamor was a medieval ancestor of Plankton and was just as evil. He lived in a castle with his wife, Karen the Crystal Ball, in a dark landscape and on somewhat of a hill, close to medieval Bikini Bottom. He is the main antagonist of the episode " Dunces and Dragons."
Planktonamor looks old-aged, considering that he has a grayish-white beard. He looks the same as Plankton, but he wears a big light purple cloak with a brown belt in the middle. He is also the same size as Plankton.

Princess Pearl, he was found by SpongeBob, Patrick, Squidly Tentacles, and the Dark Knight, and was almost victorious, but was zapped by his own dragon jellyfish after it ate SpongeBob's Krabby Patty and became obedient to SpongeBob.

Like his descendant, he was enemies with the Mr. Krabs of his era.
