Biometal Model FX is the Mega Man transformation for Vent or Aile from Mega Man ZX by combining Model F with Model X. It's design takes inspiration from Fighting Fefnir from the Mega Man Zero series.
Similar but not the exact same as Atlas' Model F, Model FX can be identified by the arrow design on the helmet present across most biometals combined with Model X.
