Door Mask was in charge of the abduction of EAGLE's new Super X computer, stolen from a base and placed within a train to transport to the Black Cross for a plot to use it to align their satellites to drop bombs for destroying Tokyo. When he initially faces the Gorengers, he uses misdirection to trap four members into a box with a bomb lock holding them; however three of them escape using Kirenger's strength and his Birdies, while Akarenger digs underground using his Drill Bute to escape. Eventually Kaijo catches up with the train with the help of the computer and tries to retrieve the Super X computer from Door Mask, but the computer explodes before he can save it, appearing to destroy itself to protect its secrets.
