Reign

Reign (レイン) was a mutant-turned-demon who was previously imprisoned in the Demon Zone with his master Azazel, and is the final antagonist of Final Endings and in the Evershade manga overall. This is the original depiction of Reign, as created by Alex Guy.

Originally a human mutant, similarly to Azazel, Reign grew power hungry and eventually turned into a demon. Before Rising Beginnings, Reign was defeated and imprisoned in the Demon Zone by Lucas, but eventually escaped with Azazel and Domingo and joined his campaign against mutant kind.
