- Note: Hathaway's Flash is non-canon to the anime, meaning that the events occurring in the novel do not happened in the anime universe.
Hathaway later gave himself a new identity, Mafty Navue Erin, and piloted his own advanced Gundam to attack the Federation. He joined a anti-Federation crew called Mafty and the group caused trouble to the Federation controlled colonies. It was a ironic life-decision as his father, Bright Noa, was a dedicated Federation officer and was obligated to arrest and prosecute Mafty. Towards the end of his life, when he was trialled and sentenced to death by the Federation, Quess' spirit came to make it clear she never loved him. It was only then, in his final moments of life that he realized his actions in her name had always been in vain.
