Skadi stumbled upon the injured winged horse Aragorn in the mountainous realm of Jotunheim and she began to tend to its wounds. While tending to the horse she was encountered by Moonstar,
Meltdown and
Sunspot, mutant members of
X-Force, who informed the giantess that Aragorn belonged to the
Valkyrie. Skadi turned Aragorn over to them and they traveled to Valhala, where they confronted the death goddess
Hela and the dark elf
Malekith.
