The unveiling of the AEU-09 AEU Enact to the world in AD 2307 utilized the AEU Enact Demonstration Color (a color variant of the AEU Enact Commander Type), piloted by AEU ace pilot Patrick Colasour. The joyous occasion was marred by the sudden appearance of the Celestial Being's GN-001 Gundam Exia, which proceeded to take down the AEU's latest mobile suit swiftly. Patrick subsequently switched to a regular colored AEU Enact Commander Type.
During the AEU's joint military exercise with Republic Of Moralia, Patrick participated with his Enact Commander Type and led a team of AEU-05/05 AEU Hellion Perpetuums. When the Celestial Being's Gundams appeared and intervened in the event, Patrick and his team confronted the GN-005 Gundam Virtue. However, as they approached Virtue, they were attacked by its GN Cannons. Patrick and his mobile suit managed to evade the blast but his teammates were obliterated.
