These individuals fell under the sway of Earth-Man and his xenophobic claims that Superman was a native of Earth who worked hard to protect the planet from alien threats, in which purportedly one of Superman's greatest achievements is protecting the planet from the dreaded Martian Manhunter. The Justice League of Earth spread their ideals of distrust and hatred against aliens across Earth and were able to successfully convince the  planet's inhabitants into believing them, resulting in the planet falling under the dictatorship of Earth-Man, seceding from the United Planets, and a massive persecution of aliens among Earth's people. The Legion of Super-Heroes were also branded as fugitives for perpetuating the "lies" of Superman's true origins in which the Justice League of Earth was tasked into hunting them down. The Justice League of Earth captured many Legion members and this allowed them to have their powers absorbed by Earth-Man, and he used the Legionnaire Sun Boy to turn many of the suns in the  galaxy red.

Superman and the others encounter two more Legionnaires: Night Girl and Shadow Lass, who lead them to an improvised underground headquarters from which over ten thousand extraterrestrials have escaped to their home planets.

Brainiac 5  manages to free Sun Boy from the machine. Once he returns to consciousness, Earth's sun once again emits yellow rays, restoring Superman's powers. The Man of Steel is then able to face Earth-Man on equal footing, convincing Earth's people of the truth of his origins in the process. With the Legion's help, Superman is able to subdue Earth-Man.
