When Shroud summons the Darkforce in California, Captain Marvel emerges from the Darkforce Dimension. She joins Wasp, Ant-Man and the newly-arrived Thor to stage the retaking of Avengers Mansion. After Ant-Man causes a power outage in the mansion, Black Knight and Captain America escape their bonds and join the other heroes to defeat Mr. Hyde. Ant-Man beats Fixer and Thor drains the Asgardian powers of the Wrecking Crew. Dr. Druid arrives and mentally forces Blackout to drop the barrier around the Mansion. The panicked Moonstone flees and Captain Marvel pursues her into the side of a cliff. Baron Zemo regains control of Blackout and orders him to send the entire mansion into the Darkforce Dimension.
Ant-Man and Wasp defeat Absorbing Man and Titania (Av #275, ’87). Blackout draws himself and Moonstone into the Darkforce Dimension (Av #238, ’83).
The now-bearded Thor rejoins the Avengers, a status that is recognized in issue #278; he still bears injuries inflicted during the Mutant Massacre in Thor #374, ’86. The editorial note that Thor appears here between pages 5 and 7 of Thor #373 is incorrect; he appears in this issue and the next between Thor #374-375, ’87.
