The repulsive-looking mutant known as Masque is ironically gifted with the ability to shape other people's appearance. Unable to affect his own hideous face, he grew to obsessively loathe beauty in every form. His origins are a complete mystery. In coalition with other outcast mutants who were unable to adapt to society, Masque helped to found the Morlocks, a hidden community of mutants who lived underground in the tunnels of New York City.
Although most of the Morlocks are peaceful, Masque has always showed vile intentions. After seizing the leadership of the Morlocks, he radicalized the group as a band of extremist terrorists. His stance led him to be ultimately forge an alliance with the Brotherhood of Evil Mutants and to be executed by X-Force member Shatterstar. Years later, it was revealed he had survived, now with the ability to alter his own body. Eventually, he returned to his old ways.
When mutantkind migrated to the island nation of Krakoa by Professor X's initiative, Masque joined the new mutant society alongside other villains. Alongside other Morlocks, he has been granted a luxurious lifestyle financed by the Hellfire Trading Company. In order to assist the Hellfire Trading Company's pirates known as the Marauders, Masque once again leads the Morlocks to battle.
