Masque was one of the few Morlocks to escape the Marauders in the Mutant Massacre . Masque teams with The Tunnelers, a small group of Morlocks. They are initially rescued by X-Factor after a fight with Iceman and Beast. Masque's powers are nuetralized by Leech, whom the Morlocks believed to be in danger from X-Factor. Ultimately the Morlock Scaleface convinces everyone to make peace. Both groups barely escape the incinerating flames of Thor's funeral pyre for the rest of the slain Morlocks.
Not wanting to live life above with X-Factor, the group sneaks out, using Masque's disguise capabilities. Unfortunately they soon encounter a mutant hating street gang. In the resulting fight, Blow-Hard is slain and Masque is injured. He vanishes from the book at this point; later, his ally Berzerker seemingly declares he is dead. The cops surround the survivors and multiple misunderstandings end with the deaths of Scaleface and Berzerker.
After the slaughter of most of her brethren, Callisto travels to Moira MacTaggert's hospital on Muir Island, to be with the few surviving Morlocks. When Callisto returns to New York to seal off the tunnels of the X-Mansion connecting to the Morlock tunnels, she is kidnapped by new Morlocks, now under Masque's leadership. Masque gives Callisto a pretty new face of a top supermodel. She soon encounters Colossus. He falls in love with her. Masque teams the Morlocks with Toad's Brotherhood of Evil Mutants, but in one of their first battles against X-Force, led by Nathan Summers, Masque is apparently killed by Shatterstar.
Masque returns, wearing a full-body outfit costume resembling Marilyn Monroe .Masque rules an underground cadre of mutant gladiators that fought for fame and the right to control defeated fellow warriors in combat. Here, he uses his powers to manipulate Callisto, giving her octopus like arms, and Storm into becoming the greatest gladiator. Callisto and Storm eventually rebelled and defeat Masque yet again.
Masque has reappeared, leading a band of Morlocks in search of Magneto, hoping to inform him of a prophecy that says mutants may yet come to rule the world. To this end, they have assaulted and maimed Caliban and abducted Leech. Recently the group set off a bomb in a packed Subway train and Masque used his powers to disfigure the humans on the train. Masque also made a video of why they did it and what is to come and posted it on the internet.The Morlocks attacked Warpath and Hepzibah when they got too close, but the heroes quickly fled only to attack again soon after. But, both heroes were soon captured by the Morlocks. Masque began torturing Warpath with his powers, planning to kill him until Bliss begged him to stop. He moved on to set off an explosion that killed many of their fellow Morlocks and allowed them to capture Skids, Storm, and Caliban.
After the effects of M-Day Masque is one of the few mutants to retain their power. After Cyclops says that Utopia is welcome to all mutants,Masque comes and now resides on Utopia. Her and some of the other refugees are often seen to question the ways of The X-Men.
Masque was seen during the First To Last Arc with Bliss and Toad. The three went to Cerebra to force information about the situation outside from Irma Cuckoo.
Masque's powers allow him to reshape the organs and flesh of organic beings. He can disfigure faces, or, like with Callisto, give people unusual deformalities. He eventually was able to alter his own flesh, but prefered to stay in his hideously disfigured form. Often, Masque would disfigure his fellow Morlocks in order to force them to feel even more rejected from society, pulling them together in a sick, twisted way. He often tried to mutilate the beautiful face of Sally Blevins (Skids), but her protective force field stopped him from doing so.
