Aile (エール) 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. Aile means "Wing" in French. She is a tomboy that appears to have between 11-15 years old.

History
10 years before Mega Man ZX, Aile went with her mom to the fair, where Mavericks attacked. The Slither Inc. forces repelled them, but Aile's mom was apparently killed.

Mega Man ZX
Aile is the chosen one for Biometal Model X, and through Double Megamerge can use the other Biometals. In the first game Aile fights to defeat Serpent and destroy Model W. It is unknown if Vent and Aile are related. It's also unknown if the two kids had met at the fair.

Mega Man ZX Advent
In the second game Aile returns in Grey's story. She is 18 years old, wears her shirt open and 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 when you receive "the Chosen ones" cipher when you defeat Aeolus.
