Awarded for destroying Exusia.
Due to the server closure, this trophy is no longer obtainable. Exusia is the final boss in Story Mode, yet the trophy will NOT unlock as it was only by encountering this AC in Territory Missions that this trophy unlocked. Safe to say that this was very tough, but made a lot easier by having a strong team on your side. The same applies for AC's LLL, St. Elmo, Raijin and Type D No. 5 and their respective trophies.
