During the final space battle of The Second Neo Zeon War, Quess Paraya (a girl who a teen Hathaway Noa was in love with) gets accidentally killed by Chan Agi (who pilots a damaged Re-GZ) while trying to protect Hathaway. Then Chan is herself killed by an enraged Hathaway in a Jegan.

All these tragic events would haunt Hathaway for the rest of his life and serve as catalysts for his transformation into Mafti Nabiyu Erin years later. Under this alias he commands the eponymous terrorist organization and pilots the Xi Gundam against the now corrupt Earth Federation.
