She first appeared as a member of the Nevada mutant brothel, the X-Ranch. After the hate group the Church of Humanity destroys the ranch, Stacy joins the X-Men. Forthright and argumentative, Stacy did not take easily to teamwork and left the team shortly after joining. 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. She also proved to be a highly skilled fighter, even giving Wolverine a proper workout. Where she got this training is unknown, much like everything else about her past.
