Masque first appeared in the Morlock tunnels after Callisto kidnapped the X-Man Angel to be her unwilling groom. Masque later joins in on Callisto's kidnapping of Shadowcat (Kitty Pryde), to force her to go through with her promise to marry Caliban in exchange for his assistance in getting the Morlock, Healer, to help Colossus, after being left melted by Pyro and flash-frozen by Avalanche using liquid nitrogen. As part of their plot, Masque uses his power to turn the corpse of a teenager into a perfect copy of Kitty. However, the body is exposed as a fraud by Wolverine's enhanced sense of smell (a factor Masque and Callisto had not taken into account due to Wolverine being absent when the X-Men first met the Morlocks). Masque uses his powers without Callisto's permission, to rapidly age the faces of the members of Power Pack as part of a plot to kidnap them for a fellow Morlock, whose own children had recently been killed.
