History: Of all of the students who have attended Professor Xavier's School for Gifted Youngsters, the mutant girl called M is the most mysterious.

M, also known as Monet St. Croix, is a teenage Algerian who lived in Monaco and is the daughter of Cartier St. Croix, the wealthy former president of several corporations.

Monet first came in contact with many of her future classmates at Xavier's School when she and they were captured by the alien techno-organic race known as the Phalanx. Following the defeat of the Phalanx, Professor Charles Xavier, founder of the X-Men, decided to see to it that M and her fellow teenage mutant captives were instructed in the uses of their powers. Therefore, he established a new version of his School for Gifted Youngsters at the Massachusetts Academy in Snow Valley, Massachusetts. M and her fellow students thus became the team known as Generation X.

As time passed there was a series of surprising revelations about the usually aloof M. It turned out that the silent aborigine mutant Gateway had been her mentor. It was revealed that Generation X's most implacable enemy, Emplate, was actually her brother Mariu. Oddly, she would at times go into an autistic state when she engaged in intense thought, and at other times she would shift from her usual mature, sophisticated personality into a childlike one.

Recently Monet abruptly divided into two separate little girls, the twin sisters Claudette and Nicole St. Croix. It appears that these are her true, original forms, and at some point in her past the two sisters merged into Monet, whose physical age is the same as that of the combination of the twins' ages. It also appears that the merger gives Monet superhuman abilities that neither of the twins can utilize on her own. Even more astonishing, after the twins merged again into Monet, she somehow fused with Emplate to become a dangerous being called M-Plate. As of now, the full story behind M and her different forms is as yet to be revealed.

Height: (as M): 5 ft. 7 in.
Weight: (as M): 125 lbs.
Eyes: Brown
Hair: Black

Stength level:(as M): Superhuman Class 10 (at least)

Known superhuman powers: The twins Claudette and Nicole St. Croix are mutants with the superhuman ability to fuse into a single being, known as Monet St. Croix, or M, whose physical age equals the combination of their chronological ages. (In turn Monet can fuse with her brother Emplate to become the superhuman being known as M-Plate.)

As Monet or M, she possesses various superhuman powers including superhuman strength, the ability to fly, telepathic powers (whose range is limited, though those limits have not been specifically defined), and superhumanly acute night vision. She also possesses extraordinary intelligence, although it is unclear whether it reaches superhuman levels.

Other abilities: Due to her extraordinarily high intelligence, M is an excellent scholar.

NOTE: Amarilis played her in Generation X made for T.V. movie.
