Alien Rayblood (レイブラッド星人, Reiburaddo Seijin) is an enigmatic entity and the creator of the Reionics, as well as the one who gave Ultraman Belial his dark powers by fusing with him. Though his body was destroyed centuries ago, his spirit continued to exist in the present day through his possession of the original Belial's body, until he was separated from it by Ultraman Geed.
