History
Little is detailed about Moondragon's life before the zombie plague arrived on Earth-2149, however it can be presumed that it followed much the same path as her Earth-616 counterpart.
Presumably, Heather received a call from Nick Fury to join the resistance aboard the S.H.I.E.L.D. Helicarrier and left to join them. With the extremely varied bunch all assembled on the Helicarrier, Nick explained how serious he believed the situation to be: the end of the world. He also explained that whatever the histories of those assembled, they were all on the same side.[1]
It can also be assumed that she was part of the team sent back down to the surface to battle the zombies, unsuccessfully, it would seem as a zombified Moondragon was a part of the zombie masses that tried to prevent Magneto and his small band of survivors from escaping to the Baxter Building.[2] What became of her afterward is unrevealed.
