GFAS-X1 Destroy Gundam is a giant transformable mobile suit developed by the Earth Alliance's elite force, Phantom Pain. The prototype was assigned to Stella Loussier before one of the mass-production models was later handed down to her fellow pilot, Sting Oakley. Due to the terminology used in Cosmic Era, it is still referred to as a mobile suit rather than a mobile armor. True to its name, the Destroy was developed to completely annihilate enemy forces single-handedly, effectively serving as a one-man army.
