In the early days of her time as a member of the New Mutants, as depicted in "New Mutants" #3, Dani experienced a vision of the Demon Bear. Initially, she believed it was simply a nightmare, born of the childhood fear that the bear which had killed her parents would one day come to kill her too, but when she attacked the bear with her hunting knife, she drew blood, and realised that the bear was both real, and no mere animal. Increasingly troubled by her dreams of the Demon Bear, Moonstar ran various Danger Room scenarios against bears, and then confronted the demon alone; he mauled her and severely damaged her spine. The New Mutants rushed her to the Mid-County Medical Center. The Demon Bear infiltrated the hospital, transported the team to the Badlands, and turned nurse Sharon Friedlander and officer Tom Corsi into demonic Native American warriors under his control. They later reverted to normal humans, but still kept the appearance of Native Americans. Here the New Mutants fought and defeated the Demon Bear, disrupting him with Magik's Soulsword. Danielle's parents leapt from his body, returning them to normal.
