Zamasu is a lean-built individual of fairly tall height. He has pale green skin, gray irises, white eyebrows, and white hair in the style of a mohawk. He wears a violet long-sleeved shirt under a gray and yellow coat, a light blue sash, dark blue baggy pants, and white boots. He also wears orange Potara-like earrings. Future Zamasu is obsessed with his own immortality and often showing his sociopathic and egotistical attitude with long speeches.
