Model X

Model X (モデルX), the Blue Mega Man is obtained by Vent/Aile in the beginning of the ZX game, with a Biomatch created by their sense of justice. Model X's attacks are based upon those of Mega Man X and consist of an X-Buster, which can charge and release blasts of energy on three levels identical to X's upgraded buster in Mega Man X2, able to fire two charged shots in a row when fully charged. Model X can also be used to Double Megamerge (ダブルロックオン) with other Biometals, allowing Vent/Aile to utilize the ZX, HX, FX, LX, PX and OX Models.

Model X's password for the gate inside Area M is Lumine Infinitus (Infinite Light), referring to X's "Limitless Potential".
