BlackJack SquarePants is the muscular cousin of SpongeBob, Todd, and Stanley, and the main antagonist of the episode of the same name.
Information[]
Blackjack SquarePants was exactly the same size as SpongeBob until he went to jail and probably got smaller cause of the lack of food and no exercise and shrunk to the size of SpongeBob's toe. Blackjack has a very gruffly voice and is circled shaped, compared to SpongeBob's square shape he also has very muscular arms for his small size. He dresses up in Biker-Gang clothing (white shirt, red wrist bands, blue jeans with belt buckle like SpongeBob's, and black cowboy-like boots). He has a pet worm, and lives in a cabin-like house only next door to his Uncle Blue SquarePants' house. Blackjack is known to be tough.
Trivia[]
