M (Monet Yvette Clarisse Maria Therese St. Croix) is a fiction comic book superheroine, a mutant who appears in the X-Men family of books published by Marvel Comics. Created by writer Scott Lobdell and artist Chris Bachalo, she originally was a member of the teenage mutant group Generation X (1994), and now appears in the series X-Factor.

Monet St. Croix was born in Sarajevo, Bosnia and is the eldest child of the rich and eccentric Ambassador Cartier St. Croix and his Algeria wife. She grew up as a pompous and spoiled rich girl as a result of being the favored child of her father. Shortly after her mother’s mysterious death, her brother Marius, the vampiric mutant known as Emplate was banished from the St. Croix home. He eventually returned after learning the dark arts and requested that Monet join him in conquering another dimension. She cruelly rejected his offer and after finally having enough of his sister's ridicule, Marius transformed her into a red-skinned, untouchable, mute creature whom he nicknamed Penance. Monet's younger sisters, Nicole and Claudette, heard the commotion and quickly went to her room. When they could not find Monet, they assumed that Marius had killed her. The twins then banished him to another dimension while Monet followed, believing it was her only way to revert back to normal.

Afraid their father would break down after the loss of his favorite child, the twin sisters decided to merge bodies and replicate Monet both mentally and physically. This version of Monet would have been identical to the original if it weren't for Claudette's autism. Since both the twins' minds were combined, Claudette's autism would sometimes take effect, leaving "Monet" in catatonic stupors. Subsequently, while the twins were impersonating their sister, they were among the new generation of mutants captured by the techno-organic alien race known as the Phalanx.

The twins (under the guise of Monet), helped to battle the Phalanx until she and the other teenage mutants were rescued by Banshee and Emma Frost. The group soon formed the Generation X team with Sean and Emma acting as co-headmasters of the new school designed to train them in the use of their powers.

M (Monet St. Croix) has not been a contender in any CBUB matches.
