M

Origin and history

Monet as a member of Generation X

The twins, or the M Twins as they were later dubbed, were at some point mentored by the Aboriginal mutant Gateway before they were taken by the alien Phalanx, along with a number of other mutants. Still posing as their sister, the two young girls continued to perfectly imitate Monet when they joined their fellow captives as founding members of the mutant youth group Generation X.

Their facade would be challenged during the team's encounter with Emplate which caused headmistress Emma Frost to grow tired of "M"'s secrets. Emma Frost tried to use her masterful telepathic abilities to pry into the girls' mind, but they were capable of repelling her intrusions.

Monet trapped in Penance's body

After a run in with Bastion and the forces of Operation: Zero Tolerance the twins' facade would come to an end. Following a fierce explosion that buried "M" underneath a destroyed building, the twins emerged from underneath the rubble as two separate entities. The M-Twins then fell into a coma where their older sister (still trapped in the Penance form) would watch over them as they recovered.

During this time, Emplate reemerged hoping to recapture all three of his sisters. The sound of his voice awakened the twins from their coma and they once again merged into "M" and then also merged with Emplate. The twins then used their telepathic powers to find out how he escaped the dimension they put him in, as well as the true fate of their sister Monet. Emplate tried to take control of their gestalt form, but the twins broke free of Emplate after they were caught in another explosion.

The twins then relayed their story to the rest of Generation X and used their powers to free the real Monet from Penance's body. As a result the twins became trapped in Penance's form before being freed shortly after.

Free at Last

Learning that his children were alive and well, Monet's father, ambassador Cartier St. Croix, hurried to the school to see the children he thought he had lost. He quickly pulled the three girls from the school and transferred Monet to an academy in the Swiss mountains.

There she discovered that her headmaster was in fact a vampire and had been feeding on his students. She killed the headmaster of this school and quickly returned to Generation X. Soon after, Monet began to date her teammate Everett Thomas, also known as Synch, until he died trying save everyone on the team from a bomb implanted by Adrienne Frost.

Monet took the loss of his life hardest out of all of the Generation X members. Monet soon started to open up to her fellow teammates until the team realized that their leaders ( Banshee and Emma Frost) were no longer reliable mentors. She returned home for a while before joining Banshee's militant group known as X-Corps until its closing. She then joined the Xavier sponsored international mutant group X-Corporation until it too was dissolved following the events of M-Day.

X-Factor

M: Cover Girl

Monet recently joined X-Factor Investigations , a private detective agency run by Multiple Man in Mutant Town, New York. Monet also recently appeared on the cover of Vanity Fair. M is first seen catching Rictor from falling after a evil dupe pushed him off a ledge. She then goes to Madrox and Siryn to read the mind of a woman who won't talk. She read the woman mind and tell Madrox she will handle it. She finds the airplane the man who committed the murder and telepathically create a illusion where the man tells the passengers what he did.

Team relations become more complicated when a drunken Jamie Madrox creates duplicates that, without him knowing so, sleep with both teammates Siryn and M in one night. Both women seem enamored with Jamie following their late night tryst, however, when Jamie confesses Monet immediately throws him out of a window. Monet then begins to continuaslly slam Jamie against a wall in order to find the dupe that she slept with, causing frightened clones of Jaimie to emerge without a single confession. Without resolve, Siryn and M begin to ignore each other, but the young Layla Miller demands that they mend the issues between them. Monet quickly opts to go on a shopping trip to Paris for the two, and they subsequently become close and more comfortable with each other.

X-Factor

While the two are in a restaurant, a gang outside attempts to set a building that houses mutants on fire.  M and Siryn quickly rush to defend the building, but M becomes infuriated when a bullet bounces off of her chest and shatters her Fabergé egg. The scuffle is brought to the attention of the local police, and the two decide to surrender themselves rather than creating a media frenzy with mutants yet again in the wrong. In jail, a man from the earlier riot walks by, bragging about burning the building and the lives he took. M breaks a bar from the cage and throws it at the man, stoically infuriated with his remarks. We soon see that M eventually crucified the man with bars from her cell before she and Siryn escape from the prison. Soon after, the pair return to the building, to find a little girl named Nicole sitting on a doorstep. The girl reveals that she is now an orphan due to the fire. This reminds M of her own younger sisters and she immediately grabs Nicole, telling Siryn that she is take them taking her with them back to the United States.

With new found respect for one an other, M and Siryn decide to team up again after Jamie asks them to attend to a clients job involving a custody battle involving two young twins who sing for the down fall of mutants. The two women go to see one of the children's concerts and after a couple of jokes, they quickly make their way back stage. Once there, Siryn is nearly shot in the head but the bullet grazes her skull,  knocking her unconscious. M begins shouting at the sniper, but is snuck up on and is knocked unconscious when a chloroform filled rag is placed over her mouth. We next see the two locked up in a cabin with M being chained to the floor, while Siryn is gagged and bound to a chair. Their kidnappers are revealed to be Clay and Solo. Solo's suit refracts light which enabled him to sneak up on Monet.

M and Siryn

With much effort, M finally breaks free of her chains, and when she knocks down the door of the cabin, Monet and Siryn find themselves in the middle of a desert like place. The two waste little time flying back in order to find the kids, with M, simply taking the elevator that they are currently in, along with their parents. M drops off the elevator on top of a rocky stand where a camp has been set up by the children's grandparents. However, it is soon revealed that this was all a ploy by the Isolationist to simply keep the two women, especially Monet, away from the team. When the two cannot contact any of their team members, M quickly flies back to their base, and catches the Isolationist, about to crush Rictor with a car. However, he throws the vehicle at M and quickly leaves the area.

During the Messiah Complex, M was rarely seen but eventually took part in the final battle on Muir Island.

Soon after this event, a generous Monet decided to buy all the women of X-Factor iPhones, but when Wolfsbane revealed she was leaving the team, M crushed it, promising her Layla's if Wolfsbane ever comes back. It is ironic to note, that while Monet purchased an iPhone for Layla, she seems convinced that the girl will not return. Later she is seen talking to Siryn about her pregnancy and suggests an abortion, although Siryn dismisses the idea immediately. M also states that she and Siryn are now best friends,  considering that Wolfsbane has left, M would be the best thing she's got.

After Rictor is kidnapped by Arcade, Monet's superhuman hearing is the only thing that is able to help track down X-Factor's captured teammate. When she finds him, she's electrocuted with apparently enough electricity to kill twenty grown men, and is knocked out. With her hair the only physical indication of her electrocution, a still rattled Monet confuses her teammates' names with those of other X-Men but still manages to use the head of one of Arcade's robotic henchmen to find the source of its control. Unfortunately, when the team arrives at his hideout, Arcade had already escaped and had set a bomb, that upon detonation would cause Mutant Town to implode.

Secret Invasion

Monet, along with the rest of X-Factor, recently did their part against the Skrull invasion of Earth during the Marvel event, Secret Invasion.  The team clashed with She-Hulk and her partner Jazinda, who were after a Skrull posing as Longshot unbenknownst to the team. 

While X-Factor tried to protect "Longshot" (who was accompanied the former X-Man Darwin), Monet and She-Hulk's attitudes clashed and the two physically battled, hurling insults at each other before eventually combining forces.  Darwin's powers unwittingly revealed the Skrull's guise and X-Factor and She-Hulk took him into custody.

After the team allowed Darwin to stay with them, he developed a crush on Monet, which may have stemmed from his adoration of her Vanity Fair spread.

AOA Monet

Age of Apocalypse (Earth-295)

Monet, known as Know-It-All, appeared in the alternate reality known as Age of Apocalypse as a member of the Generation Next team, led by Colossus and Shadowcat.  She was never seen in person, only on a computer screen, making it likely that she used her mutant powers to fuse with the mainframe computer. When Magneto needed to locate a mutant with chrono-temporal powers, Know-It-All used her abilities to search through Apocolypse's files, locating the best match in Illyana Rasputin, who was being held at the Seattle Core. During the rescue mission, Know-It-All kept Colossus and Shadowcat updated. After the fall of Apocalypse, it is not known what happened to Monet. As for her siblings, the twins were apart of Apocalypse's elite task force along with Emplate and they fell into a permanent catatonic state when Emplate died in battle, however, it is theorized that the twins could have been returned to Monet, although, none of them have been seen since the downfall of Apocolypse.

Know-It-All had a heightened intelligence was able to communicate with computers and other mechanical systems, using them to search through online databases for information.
