Part shark, part octopus and part stingray, Mocktopus is a giant sea monster with a tendency to mock what people say. With his high-pitched voice and self-defeating ways, Mocktopus is more dangerous to himself than he is to others. He is a member of S.I.C.K. and has a very sarcastic attitude, but eventually reforms and sides with the heroes in Season 3.
