Kidou Senshi Gundam: Senkou no Hathaway

In Hathaway's Flash. 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 false name "Mafty Navue Erin." The organization Mafty is fighting a terrorist campaign against the Earth Federation government, and they are eventually able to 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 power.
