Upon exploring the subways beneath Shinjuku, Domon discovered the Devil Gundam and something else that shocked him: several of the other nations' Gundam Fighters were under its control: Chibodee Crocket, Sai Saici, Argo Gulskii, and George de Sand were all under the influence of the DG Cells, and to make matters worse, Master Asia was allied with the Devil Gundam not because he was under its control, but because he believed that he could use the Devil Gundam to remove mankind from the Earth so that nature could restore itself. The other Gundam Fighters were saved by the sacrifice of the old Shuffle Alliance. The Devil Gundam then finished evolving into its Second Stage, and it erupted from beneath the ground. Domon fought the Devil Gundam in his own GF13-017NJ Shining Gundam and tried to damage it with his ultimate "Shining Finger Sword" attack, but due to his hesitation of wanting to kill Kyoji, Domon missed and the energy was absorbed into the Devil Gundam. That allowed the Devil Gundam to make a complete recovery, and it made its escape along with Master Asia.
