Hela, the death goddess of Asgard, creates a plan to take over the realm and kill the Allfather Odin, who is in a healing sleep at the time. Hela's magics drive Danielle mad and she has to be restrained by her friends, allies, and the unseen help of Doctor Strange. The battle is soon moved to Asgard. The New Mutants, along with the wolf-prince Hrimhari and the Valkyrie Krista (aka Mist), who resist Hela, ultimately triumph. Danielle seemingly loses her winged horse Brightwind in the battle, which concludes in Odin's very bedroom.
