In Creature from the Krusty Krab, Dreaded Patrick wears a costume throughout the whole game that includes a belt, gloves, and a suit. He also has a small patch of hair. Like his servants, army, and other starfishes, he is also pink. He seems to also be unfit like Patrick, but that is ironic, due to his high jumps and fast running, he also has some wrinkles.
Dreaded Patrick seems to be older than Patrick, and he serves as an antagonist in the game. He rules an army of somewhat paper starfishes. His personality is quite like a happiness and humorous combination, for he does not get angry easily and he loves to laugh. His first evil plan was to take over Bikini Bottom.
He has the ability to jump at alarmingly high rates, which is useful for escaping. Everywhere he goes, he has an urge to place a poster of himself, so that he may recruit new people for his army and/or to admire himself. He only seems to appear when Starfishman is around. Dreaded Patrick's intelligence is generally high, and due to the evil schemes and great plans, he is also not extremely lazy unlike Patrick. Apparently, in the game, it is revealed that Dreaded Patrick lives in a secret base located nearby Town Hall in Bikini Bottom.
In Nighty Nightmare, he wears a completely different costume that is similar to Superman, which consists of a light gray costume with a slightly light blue shield-shaped emblem on the chest, consisting of an furious black star with flaming eyes and a thick darker blue outline, a cloak which has the same emblem embedded and a thick yellow belt.
In the portable versions of Creature from the Krusty Krab, Dreaded Patrick was never defeated by Starfishman, unlike in the console versions, where he was indirectly apprehended by a ring shaped asteroid.
In the GBA version, Dreaded Patrick indirectly fights back rather than constantly escaping and leaving minions behind.
