Satan has layered blond hair that's parted in the middle and green eyes with a yellow gradient. Like all of the demon brothers, he wears nail polish, his in the color green. When truly angered, Satan can be harsh and unforgiving. Normally, he is sensible, quick-witted, and usually the voice of reason between the brothers until he comes into conflict with Lucifer. He has a tendency to overthink things. He also loves cat and study, that's why he's so smart and genius. He's the 4th oldest brothers.
