Mephisto is a member of the Deities of Death along with Death, Hela, Dormammu, and Pluto. Mephisto and the other deities came across the Mandarin of China who wanted to live forever. To help him, the deities gave him the Demon Elementals and the Bands of the Underworld in exchange for the souls of all in his kingdom. Mandarin complied and the Elementals killed everyone. When the last drop of blood was spilled, the land consumed Mandarin and his temple.
Mephisto was unvoiced and unnamed.
Mephisto and the other deities appeared in a deleted scene that was supposed to be the opening and origin of Mandarin. Since nothing in the video contradicts the events, they can be considered canon.
