Physically, the Grand Master Gundam appeared as a combination of the Four Heavenly Kings, which included the upper body of GF13-001NHII Master Gundam, the body and horns of Grand Gundam (in quadruped mode), the wings and claws of Gundam Heaven's Sword, and a much larger version of the Walter Gundam as its tail. The majority of the behemoth was colored black, with the Gundam Heaven's Sword's feathers and talons, the Grand Gundam's cannons and horns, and both the Walter Gundam and Master Gundam components being the only parts in their original colors. The entire machine is also suffused with green tentacles/cables, similar to most of the Devil Gundam's spawns.

Being infested with DG Cells, the Grand Master Gundam could regenerate from astonishing amounts of damage and reshape its form at will. While attempting to recover from the Erupting Shuffle Alliance Attack, it transformed Master Gundam's left arm into a powerful beam cannon and manifested large masses of tendrils to bind the Shuffle Alliance's members.

During the 13th Gundam Fight, the JDG-00X Devil Gundam created the powerful Four Heavenly Kings for its own defense. By the time the Gundam Fight ended, all four kings had been destroyed, but Ulube Ishikawa had resurrected the Devil Gundam in space (with the unwilling Rain Mikamura as its core). Now back to its full strength, the Devil Gundam merged with the Neo-Japan space colony, feeding off of the colony's generator as a power source as it prepared to consume and destroy the Earth. When the Shuffle Alliance entered the colony to destroy the generator, Ulube had the generator transformed into the Grand Master Gundam and prepared to pilot it against his foes.
