Wan Dai Nan Meng Gong Entertainment announced that the series's main villain, Inferno, will be fighting "Soul Power 6" as an operable character. Inferno is the incarnation of Soul Edge's desire to fuse the evil side of the soul of all the warriors he acquires. His motives for existence are unknown, and there are claims that he is just following the desire to fight, hurt and collect souls. The strange fire surrounding his body is the result of many souls being burned. Inferno appeared in the earliest "Soul Power", "Soul Power 2" and "Soul Power 3 Arcade Edition". He was also the main villain in the early part of the series and had no entity. Inferno is the manipulator behind the series Nightmare, and he also controlled the series Ziegfey in Soul Power and Soul Power 2. In the soul ability 3, it is no longer necessary to gain physical freedom of action.
