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.

- Model Z, Mega Man ZX



Model Z is a black and red Biometal shaped after a hexagon. It is fairly similar to Model X, though the front resembles Zero's helmet from the Mega Man Zero series. The chin has a long white ridge running across the Biometal's lower half.

When merged with its Biomatch, Model Z outfits the host with primarily red armor similar to Model X; however, it lack a helmet, instead covering the user's eyes with an angular black (or dark purple) visor. The Chosen One is equipped with the Z-Saber, specializing in close range.

Model Z retains Zero's personality traits, never losing its cool even in dire situations. The Biometal is also willing to put itself at risk for the sake of those it trusts. It seems to have a good relationship with Girouette, who calls Model Z his partner. Model Z later comments that Giro is a good man.

Background
After Serpent betrayed the Guardians and seized Model W, the first commander of the Guardians created Model Z along with five other Biometals to fight the threat. Made from the soul of a legendary hero and the data gathered from Model W, the Biometal was given one of six passwords required to unlock the seal to the Model W core before the memories following his creation were erased.

Model Z eventually came into possession of Girouette, a Guardian who received orders from the first commander to protect the victims of Maverick raids before her disappearance. However, her successor Prairie was unable to understand this command until Model Z performed Megamerge with Giro, revealing the fact that only the survivors could be chosen by the Biometals.

Mega Man ZX
When Model X is discovered by a Guardian unit, Giro, now living as owner of his own transporter company is commissioned by Prairie to deliver the Biometal. Accompanied by either Vent or Aile, Girouette is separated from his protege by a Maverick attack as they head to the rendezvous point. Giro is able to repel the Mavericks as Mega Man Model Z, and eventually reunites with Vent/Aile, who became Model X's Chosen One.

During a Maverick attack on Area D, both Giro and Model Z fall to the influence of Serpent, who forces them to fight Vent/Aile. As Giro struggles to fight the influence, he suffers a lethal blow from Serpent, only surviving due to Model Z serving as life support. However, the passwords of Model X and Model Z are stolen by Prometheus and Pandora, leaving Giro and Vent/Aile at the mercy of the Mavericks. Model Z is convinced by Giro to cancel the transformation and protect Vent/Aile instead. Giro passes away, but Model Z is able to save Vent/Aile's life by performing a Double Megamerge with Model X, turning Vent/Aile into Mega Man Model ZX.

Model Z's power proves instrumental in Vent/Aile's fight against Serpent's forces, assisting in Vent/Aile's recovery of the Biometals Model H, Model F, Model L and Model P from Serpent's Pseudoroids. It also aids in the unlocking the seal to the Model W core, but Serpent takes the Model W and immediately starts Maverick attacks across the country to feed the core. The Model X Chosen One takes the fight to Slither Inc.'s head office, only to find out that the Blue Mega Man's hatred for Serpent was the final key to Model W's awakening. However, Model Z and the other Biometals, encourage his Chosen One to not give up and fight with bravery. Motivated by the words of all the Biometals, Vent/Aile defeats Serpent and is removed from the collapsing building by the Biometals. In the end, Model Z shares some final advice to Vent/Aile, telling the Model X Chosen One to face his/her destiny and carve a new future.

Mega Man ZX Advent
Four years and eight months later, only Model X and Model Z remain with Vent/Aile as the other four Biometals were stolen by Prometheus and Pandora, who gave them to evil Biomatches. However, they only discover what happened to the Biometals when the fact is revealed by either Grey or Ashe, the new Mega Man Model A after clearing up a misunderstanding over a local Model W fragment. Model Z explains that they were following the stolen Biometals, which is how they found Grey/Ashe and the Model W. When Master Albert finishes the creation of Ouroboros, Vent/Ashe joins forces with the Model A Chosen One to stop Albert, but Vent/Aile stops to fight Aeolus, Atlas, Thetis and Siarnaq while Grey/Ashe faces Albert.

After Albert is defeated and Ouroboros starts to collapse, Model Z spontaneously separates from Vent/Aile and Model X to hold back the other Mega Men while the Model X Chosen One rescues Grey/Ashe. Promising that he won't die that day, Model Z tells the four Chosen Ones that he knows their own Biometals more than they do, causing the four to be suddenly immobilized shortly before the explosion of Ouroboros. Although it is later revealed that the four Mega Men survived the event, Model Z's fate remains unknown.

Trivia

 * Although Model Z was frequently used by Vent/Aile in conjunction with Model X, neither Vent nor Aile were officially chosen by the Biometal. This is acknowledged by both characters, who consider Model Z a gift from a special person.


 * If Model OX is not counted, Model Z is the only Biometal that creates two different weapons for the user when combined with Model X, with the ZX-Buster capable of turning into the ZX-Saber and vice-versa. This feature appears to be absent when Model Z alone is used by Giro, despite Zero's mastery of different weapons in the Mega Man X and Mega Man Zero series.


 * When combined with Model X, Model Z causes the user to grow long blond hair. It is unknown if the same change occurs if only Model Z is used since the only one to do so was Girouette, who naturally had long blond hair to begin with.


 * The black visor from Model Z's transformed state is an unprecedented trait of Zero's design. The look of a visored swordsman is vaguely reminiscent of ProtoMan.EXE.
 * When combined with Model X, it instead produces a helmet more similar to the Zero series design.


 * Girouette's corruption at Serpent's hands harkens to the repeated times Zero had been used for evil in the past. Girouette's eyes glow red through the visor, the same color as Omega eyes.
 * Coincidence or not, Prometheus, Pandora and the evil Mega Men from Mega Man ZX Advent also have red eyes.
