model_ox_(mega_man)
Biometal Model OX is the Mega Man transformation for Vent (mega man) or Aile (mega man zx) from Mega Man ZX by combining Model O (mega man) with Model X (mega man). It's design is a direct copy of Omega (mega man) from the Mega Man Zero series. It allows the user to perform nearly all the special attacks Omega can use.
This is a post-game transformation, and may be considered non-canon due to the circumstances it was acquired in.
