Patar Star is a prehistoric ancestor of Patrick Star. He first appears in the episode "Ugh."
Patar looks a lot like Patrick, except he has more chest hair, a bigger mouth, a tooth on the bottom instead of the top, and flared nostrils which resemble those of a gorilla since it is prehistoric times.
He wears the same clothes as the present Patrick, but instead of pants, he wears typical caveman leopard skin-like clothes. Patar resembles a caveman. Even in those times he and SpongeGar would still annoy Squog. They are like SpongeBob and Patrick but from long ago.
He is more civilized and tame than Primitive Star. He lives in a rock just like his descendant does now.
He is very strong, playful, and curious. Patar is very foolish, even eating his own shirt, exposing him as naked. However, he is also powerful, even crushing Squog when he hugs him at the beginning. He is friends with SpongeBob and Squidward's respective ancestors, SpongeGar and Squog. However, the present Squidward isn't friends with Patrick.
He'll eat anything, just so long as it has enough salt on it. Examples are Prehistoric Gary's slime, Mr. Krabs' small ancestors, his clothes, coral, the wood, and even his own burnt hand. He was the first to notice that when he clapped it rained, but got overzealous and caused a thunderstorm, creating fire.
