His lower body is a massive spider-like mechanical structure, walking on multiple jointed metal legs. He speaks in a mechanical, glitchy manner. Example: "You... outsider... Butcher... were you?" He calls Guest "Butcher."

Background: The mastermind behind the Bigger Bodies Initiative—the "Toy Giantization Project"—conceived to prevent the downfall of Playtime Co. He is the creator of the living toys that appear in the story. A cold-blooded individual who spares no sacrifice for success, he dismissed the orphans in the company's care as "automatic drooling dolls meant only to serve superior humans." He is a hardcore mad scientist who claims he "gave the children a reason to live" through human experimentation. In a sense, he symbolizes Playtime Co., but his psychopathic thinking was considered dangerous even by other executives involved in the experiments. He is deeply feared by the toys, and no one dares approach the "Cell Block" where he resides. Appearance: When moving, he remotely operates a machine with long, slender robotic arms and legs. Head: Instead of a human face, he has a monitor displaying eerie digital eyes. Clothing: He wears a long white (gray) coat or robe that looks like several lab coats worn by Playtime Co. employees sewn together.
