Fuala Griffon commanded the BESPA Largaine base on Earth for the Zanscare Empire, utilizing guillotine executions to instill fear in Imperial opponents. She notably executed captured League Militaire member Oi Nyung after his capture by subordinate Chronicle Asher, broadcasting the event.

Her escalating brutality and instability prompted disapproval from Zanscare leadership, who ordered her to report to the Arti Gibraltir space port for return to space. Traveling there, she encountered League Militaire supporters Uso Ewin and Suzy; they initially mistook her for Suzy's sister before her true identity surfaced at Arti Gibraltir.

In space, Tassilo Vago sentenced her to exile, ejecting her into the void with minimal oxygen. This exile served as a ruse; Vago secretly recovered her and recruited her as a Newtype pilot for the specialized mobile suit Zanneck.

Operating the Zanneck, she launched multiple assaults against League Militaire forces, engaging protagonist Uso Ewin in numerous battles across Earth and space. Her campaign culminated in a final duel against Uso, resulting in her defeat and death.

Her characterization consistently emphasizes mental instability and extreme conduct, aligning her with other psychologically volatile female antagonists within Zanscare command. Her actions, particularly an obsessive vendetta against Uso following Vago's recruitment, reinforce her role as a persistent threat throughout the conflict's latter stages.
