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.
Relationship with SpongeBob[]
Cousin Blackjack is older than SpongeBob, and he used to be very abusive to him. Blackjack also calls SpongeBob a "little man" not just because SpongeBob is younger than him, but due to the fact that SpongeBob used to not make any attempt to duel with him, and used to become scared stiff.
