In a last effort to prevent defeat, the Vagans deploy their ultimate mobile suit, the Vagan Gear, piloted by Ezelcant's clone Zera Gins. While confronting the Gundams, the Vagan Gear is taken over by the SID and starts attacking friend and foe alike. After Kio convinces him to give up on his ambition of destroying the Vagans, Flit rallies both the Federation and Vagan soldiers to join forces, and work together to stop the Vagan Gear and save the Second Moon from being destroyed.
