Him appears as a yellow-skinned figure set apart by a jester's hat and a red tunic displaying a heart-shaped brooch. Mismatched striped stockings—one black and white, the other red and black—cover his legs, paired with Mary Jane shoes. Makeup persists as part of his appearance, faithful to his original depiction.

His mannerisms keep an effeminate quality, though he avoids crossdressing in this adaptation. His voice shifts between soft, effeminate tones and loud, enraged outbursts. The character's name stays unspoken due to its inherent frightfulness; even when Professor Utonium reveals it to another character, the audience hears nothing, and the mere utterance provokes visible fear.
