Model X (モデルX Moderu Ekkusu?), the Blue Mega Man, is the Biomatch of Vent /Aile and contains the soul of X. This Biometal grants the user 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 Double R.O.C.K. On?) with other Biometals, allowing Vent/Aile to utilize the Model ZX, HX, FX, LX, PX and OX forms.
