モデルO
[[Biometal]] Model O is a secret biometal usable in the post-game for [[Mega Man ZX]]. It's design is a direct copy of [[Omega (mega man)|]] from the [[mega man zero (series)|Mega Man Zero]] series. There are no depictions of a solo transformation using Model O, as every transformation in ZX by the protagonist is done by combining with [[Model X (mega man)|]]. This tag is to identify the biometal construct itself.

[[Vent (mega man)|]] or [[Aile (mega man zx)|]] from Mega Man ZX may also use this form, combined with Model X to transform into [[Model OX (mega man)|]].
