As the 13th Gundam Fight continued, the JDG-00X Devil Gundam created Four Heavenly Kings for its protection: GF13-001NHII Master Gundam, Grand Gundam, Gundam Heaven's Sword and Walter Gundam. The Grand Gundam first appeared when three of the Heavenly Kings attempted to stop Domon Kasshu from reaching the Gundam Fight Finals on time. The monstrous Grand Gundam came with several armaments, including two grand horns which could be used to impale an opponent. While the Grand Gundam usually stood on four legs, it could switch to two and use its massive front legs to crush an opponent. The four hands on the main body could also shoot out as projectile weapons or to help it move its massive frame. They also doubled as grand bombers, which could fire nearly unlimited ammunition charges. After its initial appearance, the Grand Gundam returned again during the Finals. While George de Sand fought Gentile Chapman's GF13-003NEL John Bull Gundam, the Grand Gundam appeared out of a cloud of black mist. George barely managed to repel the Grand Gundam with his rose bits. The Grand Gundam returned again when Chapman attacked Domon's GF13-017NJII God Gundam on Lantao Island. Chibodee Crocket and George came to Domon's aid and managed to destroy the Grand Gundam, but their own Gundams were heavily damaged in the battle.
