Aile

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. She is a tomboy that appears to be between 11-15 years old.

Personality
It is still unknown to whether Vent or Aile are the same person with different genders or exist in the same universe together, but it is apparent that they have different personalities. In Mega Man ZX, she seems to be more lenient towards others, excluding her foes and is a bit more compassionate than Vent. In Mega Man ZX Advent, however, her personality shifted a bit. As she got older, Aile seems to be more professional with whomever she meets, as shown when Grey was disrespectful towards her when he said, "Dudes" when addressing a "girl you've just met". She also seems a bit more cocky compared to Vent, but she's still caring.

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 in a picture when you receive "the Chosen ones" cipher when you defeat Aeolus.

Trivia

 * Aile means "Wing" in French.
 * Aile is also Turkish for "family".


 * Her appearance in outfit, hair and eye color (except for hairstyle) are identical to Vent, almost making them look like twins. But there is no proof whatsoever of what their relation actually is.


 * Interestingly, based on ciphers from ZXA, it may indicate that both stories are really just the same storyline with similar details, except the character(s) picked may just be what happened if one instead of the other became the Biomatch (not to mention in one commercial for ZX they both actually appear and work together). The same would go for Grey and Ashe.


 * After rescuing the Guardians and citizens from Area G in Mega Man ZX as Aile, the player may go to the room at the right end of the Guardian Base to change her outfit to an alternate color.


 * Aile can crawl faster then Vent.


 * Aile gets knocked back further than Vent when getting hit by an enemy.


 * Cover art for the ZX soundtrack shows Aile holding Biometal X and wearing headphones listening to music.
 * Interestingly Serpent states that she carries the blood of "the one who created model W" AKA, Albert. This could suggest that she is somehow related to Albert perhaps she is his daugther or grand daughter.
