Set ten years after the events of Gundam F91, the tale revolves around Seabook Arno and Cecily Fairchild who uncover Crux Dogatie's scheme to invade Earth with the Jupiter Empire. In response, Cecily restores Crossbone Vanguard under her birth name, "Berah Ronah," who pose as space pirates to attack the Jupiter Energy Fleet. Seabook, known as "Kinkedo Nau," is one of the top pilots of the revamped Vanguard, alongside veteran Zabine Chareux. The narrative unravels through the eyes of Tobia Arronax, a teenage Newtype who inadvertently gets involved in the confrontation between the Jupiter Empire and the Crossbone Vanguard.
While many Gundam aficionados were left underwhelmed by Gundam F91, Crossbone Gundam is lauded as one of Gundam's best due to its appealing characters, astute narration, and one-of-a-kind "pirate Gundam" designs. One cannot help but ponder how Gundam F91 would have fared had the original plan of a 52-episode TV series been fulfilled instead of compressing it into a two-hour movie.
