Hopus Pocus is a stage magician, although he also seems crazed, which is shown by his eyes (which can be cross-eyed), body languages (with him spinning his wand and having a scary smile aimed at the camera in his Death Screen) and giggles. He hides in a top hat and wields a magic wand.
He has large yellow eyes with blue irises. Hopus is a white rabbit dressed in a blue tuxedo and wears a red bow tie and white gloves.
