Aile

Aile is a main character of Mega Man ZX, and the female counterpart of Vent. She can also use the powerful artifacts known as Biometals to defend herself and others from Mavericks. She is a tomboy that appears to be between 11–15 years old in Mega Man ZX and 18 years old in Mega Man ZX Advent. She is the chosen one for Biometal Model X, and through Double Megamerge can use the other Biometals. In this game, Aile fights to defeat Serpent and destroy Model W, to put a stop to Serpent's Project Haven, which consisted of using the fear of Cyber-elves and people by creating simulated Maverick attacks, and eventually using them as sacrifices along with Aile's hatred to feed Model W and awaken it as the "Ultimate Mega Man". After defeating Model W and Serpent, Serpent divulges that all Mega Men were designed to destroy each other and survive to control Model W, and that the process was all just a game to decide the ruler of the world. Serpent then continues on to say that even she has the blood of "the man who made Model W" in her veins, which disturbs Aile. As Slither, Inc. begins to collapse, Serpent claims that destruction still awaits them so long as humans have emotions, there will always be hate, they are the true Mavericks. Aile, still troubled by Serpent's words, is reassured by Giro appearing as a Cyber-elf telling her to forget the past, that destiny is not something that is given and that her power is the key to shaping her own future. With restored confidence, Aile swears to use her power responsibly to fight for what matters. In the sequel, Aile returns in Grey's story. She is 18 years old, wears her jacket open with the addition of an emblem and has her longer hair tied up. She still uses Model ZX and has been destroying Model Ws to end the Game of Destiny. Vent and Aile also appear together in an image when the player receives the "Chosen Ones" cipher when Aeolus is defeated, revealing that Master Albert, using his government position, made sure that select individuals who reported to Legion were infused with his DNA. Aile appears in person while inside the Quarry, where she ends up fighting the Mega Man Model A Chosen One, Grey due to a misunderstanding of intentions with Model W (both think the other was trying to retrieve it instead of both wanting to destroy it). As a consequence of the fight and her remaining afterwards, Aile also ends up exposed to the fifth cipher being unlocked inside Model A alongside Grey.
