When Grey/Ashe approaches the Final Boss door, the Enemy Mega Men intercept them. Then Aile/Vent come to the rescue, telling Grey/Ashe to proceed while s/he holds off all four of them at once.
- And after Grey/Ashe defeats Albert, he/she collapses. In the outside, Model X tells Aile/Vent to help Grey/Ashe out of the place. S/he hesitates, but then Model Z demerges from her/his body, telling her/him to go help Grey/Ashe and using his hidden power to suppress the Enemy Mega Men's Biometals, making them fall to their knees. Even as a bimetal, Zero is still a badass.
Model Z: Today's not my day to meet my maker.
