Park brought Chance and her parents to the United States from their homeland promising to make them American citizens. Instead he treated them as virtual slaves, and Chance herself was forced to work selling calendars on street corners for the church. Finally tired of her treatment by the church Chance ran away.

Chance was recruited by the mutant criminal known as the Vanisher to join the group of teenagers who worked for him as thieves and were known as the Fallen Angels. A number of young mutants joined this group.Chance became the friend and partner of another of the Vanisher's thieves Ariel, who was actually an extraterrestrial mutant from a planet nicknamed Coconut Grove. For money, Chance agreed to help Ariel in her assignment to bring a number of mutants to her home planet, where an attempt was intended to be made to extract the factor from their bodies that enabled them to mutate.

The Fallen Angels succeeded in regaining their freedom, however, and returned to Earth, where Chance continues to be a member of the team until the team disbanded and she apparently, lost her mutant powers after the M-Day
