While often a background character, he has been antagonistic at some points. He was the tertiary antagonist in "The Club", along with Bobert, as part of The Reject Club. He and the other club members planned to embarass Gumball for refusing to join them.
He was also the main antagonist of "The Phone" where Gumball yells at him on Darwin's phone, causing him to attack Gumball and Darwin with his webs. He destroys their house, but he was stopped by his mother.
