Model Z

Model Z (モデルZ), the Red Mega Man, is the Biomatch to Girouette and is based upon Zero. This Model features its own Z-Saber as a weapon and possesses a visor in place of a helmet. Attacks used by Girouette in this form are based on Zero's Learning System techniques obtained during the Mega Man Zero series, including Retsuzan, Reppuugeki, Sentsuizan, Ganzanha and Rakuhouha.

Shortly before Girouette "dies" (he becomes a Cyber Elf) at the hands of Serpent, he insists that Model Z pass on to Vent/Aile. At that point, Model Z fuses with Model X and becomes Model ZX (see below).

Model Z's password for Area M is Fortitude Creed (Firm Belief), as Zero was known to fight for those who believed in him. Of all the Biometals, Model Z does not appear to have any unique abilities until demonstrated in ZX Advent where he completely immobilizes the four Biometals H, F, L and P during the epilogue.
