Is Advance of Zeta related to any other Gundam stories?
Its main focus is bridging the gap between the Gundam 0083 video series, which ends with the formation of the elite military force known as the Titans, and the Zeta Gundam television series, in which the Titans are defeated by the rebel organization AEUG. The story of Advance of Zeta continues through the timeframe of Zeta Gundam, and the court-martial of Eliard Hunter takes place after the end of Zeta Gundam, making it simultaneous with the events of the Gundam ZZ television series. Many of the mobile suits which appear in Advance of Zeta are based on machines from Gundam 0083, or are ancestors of machines which appear in Zeta Gundam, Gundam ZZ, and the Gundam Sentinel photonovel.
