Asmodeus has champagne-colored hair with long, sweeping bangs on the left side. His eyes are light orange with a yellow gradient. He is the shortest of the brothers, but often wears high heels, which makes him look taller. Like his brothers, Asmodeus paints his nails. His nail polish is pink and lime green, or sometimes teal, in a pattern that alternates every nail. Sometimes his nails are shown to be lime green and pink, while at other times his nails are teal and pink.
