Zamasu is the fallen apprentice Supreme Kai of Universe 10, a divine prodigy whose obsession with purity spiraled into a genocidal crusade. He has pale green skin and sharp, judgmental eyes that radiate a chilling sense of superiority, standing at a lean, graceful height with a refined and deceptively strong build. He is incredibly narcissistic, fanatical, and self-righteous, often displaying a calm, poetic demeanor that masks a deep-seated hatred for all mortal life.
