|Danielle "Dani" Moonstar was born in Boulder, Colorado within the Cheyenne Nation. While still in her teens, Danielle's parents disappeared while they were upon a camping trip. It was during this time that Dani's powers first manifested. The images she saw was that of a large dangerous looking bear standing over the bodies of a horse and an eagle. Dani knew, upon seeing those images, that the horse and eagle represented her mother and father as they were respectively from the horse and eagle clan.
When it was clear that her parents were missing, Dani opted to stay with friends of the family. It was during this time that her powers continued to manifest and literally scare nearly everyone within the community. It didn't take long for Dani to become an outcaste within her own 'tribe', and to be sent to live with her grandfather, Black Eagle, within the mountains. During the years that she lived with her grandfather, Dani still found it difficult to control her powers and because of that, Black Eagle contacted an old friend, Charles Xavier. When told about Xavier's school and the reason for Black Eagle contacting him, Dani was angry. Very very angry. The anger induced another uncontrollable psychic illusion which showed Black Eagle's greatest fear, his own death. Because of this, Dani reluctantly agreed to go with this Xavier, to learn how to control her powers.
However, before Xavier arrived, Danielle's grandfather, Black Eagle, was killed by agents who were tracking mutants for extermination. Dani was lucky and was able to escape with her life, and when Xavier arrived, agreed to join his group to honor her grandfather's last wish.
Her time as a New Mutant entailed many adventures and one especially that will forever be imprinted in her brain. The day she bonded with a winged stallion that she named Brightwind and became a Valkyrie. While it will be a long time before she realizes what all her responsibilities are as a Valkyrie, she definitely understands that she now has the responsibility for taking care and providing for her winged steed.
While Dani did graduated from the New Mutants, after the death of Doug, she found herself full of anger at his loss. Sadness, yes, but anger as well. Somehow she/they should have saved him, but they weren't able to. Dani shouldered quite a bit of guilt for what happened that day and she left shortly after graduation. She told no one where she was going, only saying she needed time to get her head straight before helping more at the school. Finally, after quite some time, Dani is making her way homeward bound.
