Metauro is mostly dull red, and heavily muscled. He has a gold collar and bracelets, along with glowing yellow eyes without pupils (which turn white when they cease to emit light). He wears dark red spiked gloves, as well as black suspenders. His face seems to be hidden by a bull mask of the same color as his body, with large, thick horns, a polyhedron-like structure near its top, and two gas mask filters protruding from its lower sides. He also wears a metal belt.
