Con Man is a lavender fish with light purple fins. He wears a small brown and orange top hat at the top of his head. He wears a brown vest over his light tan dress shirt with a brown tie and his sleeves are rolled up. When he was pretending to be an injured man, he was wearing white wrapping and a nebulizer, acting as if couldn't walk. In "20,000 Patties Under the Sea," he appears light turquoise in that episode. In "Snooze You Lose," he appears as lavender again.
In the episode "Chocolate with Nuts," he cons, or scams SpongeBob and Patrick out of their money three times by selling SpongeBob and Patrick chocolate bags and pretending he was seriously injured.
In the episode "20,000 Patties Under the Sea," he says, "Thanks again, boys," after SpongeBob and Patrick pay him to take the Krabby Patties they were selling, referencing "Chocolate with Nuts." He is shown with the Female Judge in that episode implying that they're married.
