Douma, in his life as a person, was considered a kind of deity because of his rainbow-colored eyes. However, the boy was never able to believe in the existence of an afterlife, using his fame as a kind of facade simply because of his extraordinary beauty.
Douma possesses the ability to easily absorb large masses of meat without needing to eat them. Therefore, Douma has extremely fast regeneration, as any damage inflicted on his body is merely a memory.
