King Poseidon

King Poseidon is the main (former) antagonist of The SpongeBob Movie: Sponge on the Run. He is the ruler of The Lost City of Atlantic City, has a golden clarinet, and is the namesake of both Poseidon Elementary School and the Poseidome Colosseum. His Roman counterpart is Neptune. Description He is a teal merman with a green tail wearing a black wig, false teeth, and a pin and a chestplate with a gold belt with an octopus on it to hide his flab. He also bears a resemblence to King Neptune as both are teal, have a tail, and are both gods. However, his true look shows him bald, with no wearing a black wig, false teeth, and a pin and a chestplate with a gold belt, he has flab. He also looks like an old man. Personality King Poseidon is a vain, flamboyant, self-centered monarch whose life mostly revolves around his looks as he believes that his facial features are what makes him a true king. He is also somewhat comedic as he overreacts to one unrecognizable wrinkle on his face in an over-the-top manner. He also had anyone who dare stand up to him executed in a flamboyant stage show. However at the end of the film when he salutes SpongeBob for having the courage to stand up against a powerful king, and frees Gary and all the snails he previously kidnapped, he redeems himself and becomes a nice guy.
