A powerful support unit resembling a horse, the mobile fighter Fuunsaiki is as much a symbol of strength as it is a mode of transport. Adorned with a crimson mask and a unicorn-like horn on its pristine white frame, Fuunsaiki primarily serves as a carrier for mobile fighters. However, its propulsion-assisted kicks are formidable enough to damage enemy units. It can also shift into pedestal mode, enabling it to leave the atmosphere.

Fuunsaiki was awarded as the grand prize of the 12th Gundam Fight, the same tournament where Master Asia emerged victorious. It made its first appearance during the Gundam Fight Finals in Neo Hong Kong, under the command of Master Asia. After Master Asia's death, Domon Kasshu became Fuunsaiki’s new rider. When Domon learned that Rain Mikamura had been kidnapped and the Devil Gundam was still operational, he took Fuunsaiki into space, using its powerful kick to destroy the Walter Gundam by decapitating it.
