Created by Jay Faerber and Terry Dodson, Adrienne Frost first appeared in Generation X #48 (February 1999).

Adrienne established herself as the "perfect child" and was the favorite of their father, with her hoping to gain his favor and inherit the Frost family fortune.

Her power allowed her to become a top 'A' student and excel in all her endeavors, and continuing to earn her father's favor.

To demoralize her, Adrienne outed Christian, to whom Emma was closest,[4] and set in motion the events that led to his attempted suicide.

[8] In retaliation, Emma shocked her sister by exposing Adrienne's secret modeling career,[9] of which their father disapproved.

Winston, having become estranged from Emma wished to ignore the video, but was placed in the public eye by Adrienne's actions.

[10] Emma approached Adrienne seeking to borrow money after her Massachusetts Academy had fallen into debt.

Initially turning Emma down because of their history, Adrienne accepted her offer after using her powers to learn that the academy was secretly the home of Generation X.

[11] As a result of the new human student body, Generation-X was forced to wear uniforms that hid their identities.

Using a combination of her powers and the Danger Room, she trapped Generation X in a simulation recreating Emma's earlier students The Hellions' demise at the hands of Trevor Fitzroy.

[17][18][19] Emma later confronted Adrienne, who made it clear that she intended to escalate the violence and endanger more students.
