He looks like Squidward, but wears a golden crown and a purple robe.
Much like his alter-ego, he is very cold-hearted towards and holds an immense dislike for SpongeBob and Patrick, even going as far as to create a new sport in which the pair inflicts harm upon themselves.
Role in episode
He is, as implied, the king of sports, also known as the Rule Giver. He creates a new sport where SpongeBob and Patrick basically hurt themselves and makes them try to break their tiebreaker. He then plays against Sandy in a series of games and is injured badly in the end, receiving his karma.
