REAL NAME: Claudette and Nicole St Croix

POWERS: Penance is a being with diamond-hard, razor sharp skin, which can slice through almost anything. However, not only can she not touch anything, but she is also mute.

When M refused to join her brother Emplate in global conquest, he turned her into the being known as Penance. Claudette and Nicole took the form of Monet and joined Generation X, and soon after the formation of the team, Penance was brought to the school by Gateway. Recently, the twins merged with Monet, allowing her to take her old form again, while the two young girls became trapped as Penance.
