Created by writer Joe Casey and artist Tom Raney, she first appeared in Uncanny X-Men #399 (November 2001), when she was known as X-Stacy, and later became known as Ripcord.

Stacy-X is a mutant with the ability to exude pheromones which she could control to stimulate bodily sensations and functions of others.

She plays a vital role in fighting Black Tom, using her powers to seduce him and releasing the other trapped X-Men, allowing them to defeat him.

Whether Wolverine convinced Stacy to completely abandon her former profession is unknown, but he did talk Nightcrawler out of whatever censure he was contemplating.

[4] After a spat with Paige Guthrie / Husk, caused by the fact that they both had feelings for Archangel, Stacy decides to leave the mansion.

[12] She is shown having a three-way sexual encounter with Welsh pop star Sugar Kane (Chamber's onetime girlfriend) and new character Ultimate Nullifier in a high-rise hotel room after they are at a nightclub.

The trio is interrupted by the sudden arrival of Magneto, who seeks to discipline Stacy for what he considers to be her disgraceful decadence which is embarrassingly tarnishing the collective image of Earth's too few remaining mutants.

However, Ultimate Nullifier engages in combat with Magneto while Stacy and Sugar Kane make their escape.

[28] Stacy X was originally supposed to appear in X-Men: The Last Stand, with Dania Ramirez auditioning for the role.
