Synopsis

Invisible Woman and Thor prevent the evil Mr. Fantastic's Gamma Bomb from destroying earth's heroes. The Magus arrives and rescues his doppelgangers of Mr. Fantastic and Iron Man from the heroes' revenge. The Human Torch flies off to clear his head and ends up battling evil doppelgangers of himself and the X-Men. Once he learns that they aren't really alive, he makes short work of his foes. Dr. Druid, Scarlet Witch, Agatha Harkness and Shaman use their mystic powers to send Earth's mightiest heroes (including Sue, Ben and Johnny) to battle the Magus in the Infinity War.
