Hathaway Noa, still haunted by his past actions (not to mention the spirit of deceased Newtype Quess Paraya), joins a terrorist organization called Mafty and adopts the alias "Mafty Navue Erin". Mafty is fighting a terrorist campaign against the Earth Federation government, and they eventually acquire the incredibly powerful prototype Ξ Gundam, which Hathaway becomes the pilot of. Using the Ξ Gundam Mafty attempts to attack a meeting of high-ranking Federation cabinet members in Adelaide, Australia to force them to vote down a provision which would strengthen the Federation's already considerable powers.
