He was once defeated by Kamen Rider but survived in the Game World. After Team Ex-Aid as the Goriders destroys the Andor Genesis spaceship, he appears as the boss of the Chou Shocker Taisen (超ショッカー大戦 Chō Shokkā Taisen, Ultra Shocker War) bonus stage of the Chou Super Hero Taisen game. During the final battle, he is ultimately killed when his red-colored Big Moraimarz Robo is destroyed by an enlarged Ex-Aid Maximum Gamer Level 99 with the aid of the Kyurangers' KyurenOh pair and spaceship ORION.
