Enma Dai-Ou

Lord Enma is a giant red oni who judges the dead. Residing in the Other World, it is his job to decide whether dead people go to Heaven or Hell. He is based on the Hindu deity Yama. He is first seen when Son Goku is killed by Piccolo during the battle with Raditz. He was until then the only person who has ever run all the way along Serpent Road, but grants Goku permission to attempt this in order to get to North Kaio's planet, which is at the end of Serpent Road. He is apparently skilled to some degree in fighting, as he claims he bested Raditz when the latter attempted to break into Heaven while passing through his realm. According to Kami, North Kaio is stronger than he is.
