In his human form, Spyro Lepton is of average height, and less muscular than most humans seen on the show. He wears a white shirt, purple gloves, and blue pants. His brown (later grey) hair is unusually styled, with two thin, upward-facing points on each side and one larger, flatter point in the middle. A dark beard which also comes down in two points adorns his chin, and he has a pair of dark, bushy eyebrows.
