It's Name is Genesic

The fight between King J-Der and GaoFighGar concludes and results in Guy's purification. J's J-Quath is shattered in the fight after the Repli-Mobile Unit rebel and sacrifice themselves to take some of the blow from the Repli-Goldion Hammer, destroying the Repli-Goldymarg soon afterwards. The Soul Masters attack J-Ark directly, and in the process Guy, Mamoru and Mikoto escape to the G-Crystal located on the replica of the moon, while J finds his J-Jewel shut down. The G-Crystal is the only thing left from the original Tri-Solar System, and it is here that Mamoru has been hiding out all this time, working to restore Galeon to its original form and programming. The Sol Masters attempt to destroy the Crystal, and their duplicate of Cain attempts to conduct Fusion with the new Genesic Galeon. It refuses, and instead reveals that Guy is within, alive and well. Guy conducts Fusion with Galeon, and Mikoto breaks a crystal plate to release the Genesic Machines, the original GaoMachines. Guy performs Final Fusion for the last time to form the God of Destruction, Genesic GaoGaiGar. Mikoto, however, is critically wounded in the aftermath. She is left nearly dead - however, if what Papillon said is true, Mikoto cannot die.
