Their young lives forever change after their first encounter with Biometal, a substance that stores the data of a Reploid or human. Vent and Aile use the M.E.G.A. (Meta-Encapsulated Granule Awareness) System, to activate the Biometals and change into a form similar to what the Biometal was based off of. They use the Biometals to defend themselves and others from Mavericks. In French, Vent means "Wind" and Aile means "Wing".
Their age is 13 years old in the ZX games. Ten years prior to the events of Mega Man ZX, they went with their mother(s) to the fair, where their mother(s) was/were killed in a Maverick attack (Vent's scenario reveals that the Pseudoroid Purprill was responsible for the incident). At the beginning of the game, Vent and Aile work for Giro Express and are asked by the Guardians to transport the Biometal Model X. They later come into the possession of Model X, and later Model Z when Giro sacrifices his life to save them. They also later obtain Models H, F, L, and P.
Both Vent and Aile work for Giro Express, but the one that the player chooses to play as is the one that Giro decides to take with him at the outset of the first game. Neither one is ever seen or mentioned in the other's storyline; however, a promo movie for the game features both of them coexisting in the same timeline. The official ZX site also says that Aile has "plenty of spunk to keep Vent on his toes", again suggesting they are in the same timeline. Their backstories are identical, and other than gender the main differences between them is different dialogue in certain scenes, and very minor gameplay changes. Though the two never come in contact with each other within the story of either game, they are shown together (along with six of the other Mega Men) in Model A's data in ZX Advent.
Young Adulthood Edit
Vent and Aile return in Mega Man ZX Advent, as young adults (now they are 17-19 years old), with Vent appearing in Ashe's story, and Aile in Grey's. Both of them still retain their Model ZX transformation from the first game. Due to the timeskip between ZX and ZX Advent (about 5 years), both now sport new looks; Aile has a long thin ponytail and Vent has Giro-like hair. Both wear blue versions of Model ZX's jacket instead of the shirts that are seen in ZX. In ZX Advent, Grey/Ashe fights Aile/Vent when the two encounter a Model W - when Grey/Ashe state their intent to retrieve the Biometal, Aile/Vent stands in his/her way, as she/he intends to destroy the Biometal. After their battle, the two become allies. Dialogue between the two after the battle indicate that Vent/Aile has known about the other Model Ws, hinting that he or she had found and destroyed a number of them between then and the end of the first game.
- Vent and Aile are both voiced by Sanae Kobayashi in Mega Man ZX.
- In Mega Man ZX Advent, Vent is voiced by Kenji Nojima while Aile is voiced by Sanae Kobayashi in the Japanese version. In the English version, Vent is voiced by Dario, and Aile is voiced by Yuko Yunokawa.
