Consul M

Consul M is a character in Xenoblade Chronicles 3. Unlike the other Consuls, she doesn't wear the red attire. She bears a striking resemblance to Mio.

Appearance and personality
M's appearance and hairstyle is identical to Mio albeit with longer hair. Unlike the other Consuls, M wears full silver armor with red lines with a gem similar to a Flesh Eater Core Crystal on her chest as well as a silver mask to conceal her face. M doesn't battle in her Moebius form unlike the other Consuls, preferring to fight in her humanoid form. In combat, she uses a dark version of Mio's Dual Moonblades. She has the power to hijack an individual's body.

Much like N, M is cold, ruthless, devoid of emotions and is loyal to him. But in reality M has suicidal depression, feeling that her immortality forced on her by N is a prison, and yearns for death.

Story arc
M is first seen alongside N during a meeting between her fellow Consuls.

M is later seen walking towards N at Keves Castle's throne room after the Lost Numbers escaped with several Cradles. As she removes her mask, she asks N what his next actions will be.

N and M later ambush the party as they attempt to escape from Li Garte Prison Camp, bringing 3 Gyrinus-type Levnises with them after Shania and several Lost Numbers betrays the group. After the party destroys the Levineses, M then volunteers to take on the party, by demonstrating her body hijacking abilities to the party, (unknown to N at the time, M switched places with Mio). Before engaging the party, M sheds a tear. After she was defeated, N overwhelms the party after Lanz and Sena's attempt to sacrifice themselves were thwarted by who used her Interlinking cancelling abilities. N then takes the party prisoner at Agnus Castle until the day of the eclipse which coincides with Mio's Homecoming.

On the day of the eclipse, after N brings the party to the Ascension Grounds (with N, X, Shania and the Queen of Agnus attending), the party, then watches in horror as Mio seemingly disappears. After the Homecoming, N then attempts to execute Noah, only for M to intervene, revealing that she was in fact, Mio, alive and well and that M took her place during the Homecoming, causing N to break down. Mio then reveals to N that M passed all of her memories to her, and that she has lost the will to live because of N's actions, using Mio's Homecoming as a means of suicide.

It was also revealed that N and M are in fact, preincarnations of Noah and Mio. In their past lives, Noah and Mio were once soldiers of the City fighting against Moebius. Noah was present when an Ouroboros Stone was activated. Later, Noah has a dream of Mio dying, with Z then appearing, seducing him. When he woke up, he was greeted by Mio at an Agnian camp, preparing their battle against Moebius. Later a dying Noah and Mio were greeted by Z as he kills his fellow soldiers in Origin.

In another flashback, Noah and Mio were seen fleeing from his soldiers, accused of treason. After that, they were later seen freezing in a blizzard.

In yet another flashback, Noah arrives just in time for Mio to give birth to her son, but she soon dies couple years after giving birth with his son in his hands grieving her loss, Noah then also dies, leaving his son behind.
