During the initial attack of the Black Cross Army against the Japanese EAGLE bases, Warrior Mask attacked the Touhoku branch, killing everyone with Akira Shinmei the only survivor of the attack.
Warrior Mask steals a new weapon in development, which transforms objects into sand. His ultimate plot was to take this weapon into space and fire it changing Earth into a lifeless planet. In order to mass produce this weapon Samurai Mask took the lead doctor hostage and threatened to kidnap his son if he didn't comply to their demands. Samurai Mask is proficient in hand-hand sword combat and archery. He is also able to use a jutsu that transfers his life-force into a spirit, allowing him to resist the Goranger Storm attack. He meets his demise when the Black Cross missile he possesses is blown up by a demolition ammo armed Bluecherry.
