Machina finds Qun'mi, with most of her body encased in stone, and asks for the power of a l'Cie so that he can become strong enough to protect Rem. She grants it to him, then her mask falls off and she crystallizes. Machina picks up her mask and puts it on, his outfit turning white in the process. Using his new power and appearance, Machina infiltrates the Milites army as a means of spying on them. During the attack on Milites by the War God Alexander, whom Caetuna summoned, Machina shields himself and Qator before escaping on Qator's Magitek.
Afterwards, he is approached by Rem, now a Suzaku l'Cie. With Rem unaware of who he is, the two of them confront each other in battle. In the battle's climax, Machina is thrown into a wall and his mask slips off just as Rem rushes forward to attack. She is impaled on his rapier, and reaches out to him, saying his name, before falling to the ground. He cries out in anguish, then kneels down beside her. Machina apologises for attacking her, saying that he only became a l'Cie because he was afraid of losing Rem and being left alone. Before she dies, Rem forgives him and tells him not to forget her.

Later on, after learning the circumstances of his older brother's death, Machina bears a grudge on Ace who has put his remorse for Izana's death aside to continue fighting.
