Moonstone and Blackout returned as members of Baron (Helmut) Zemo's Masters of Evil, participating in an occupation of Avengers Mansion and trapping Rambeau in the Darkforce dimension. With help from The Shroud, Rambeau was able to escape in time to help retake the Mansion. During the battle, Moonstone became temporarily paralyzed and Blackout died. Another of Rambeau's major early foes was the murderous interstellar pirate Nebula, who shanghaied Rambeau into space for an extended period before she reunited with the Avengers.
