He is interrupted by New Earth Superman, and they talk about Gog and the danger he represents. Superman demonstrates that he is more powerful than his younger counterpart when he hears something in Gotham City that New Earth Superman cannot. Arriving in Gotham City, they both confront Hercules, who has survived a battle with Gog. Hercules attacks and injures New Earth Superman, but is defeated by the Earth-22 Superman. After returning to JSA headquarters Superman and the JSA are attacked by Gog. Gog proves to be an equal match for the entire JSA, and it is only when Amazing-Man absorbs the properties of Gog's staff that the fight turns. The fight transfers to the African Congo, where they find the true Gog has revived. The true Gog removes his powers from Williams, killing him, and reclaiming all of his own powers. Superman remains with the New Earth JSA. He is suspicious of the revived David Reid, who has been revived as Magog, and fearful that Reid will become like the being he knew on Earth-22. The "Daily Planet" is attacked and flooded with a green gas. Superman arrives and has a flashback to the time the Joker attacked his world's "Daily Planet". The green gas is filled with kryptonite, which has no effect on Superman other than to cause his eyes to sting. Superman captures the terrorists and questions them. They reveal Lex Luthor hired them. Superman is about to kill the terrorists but is stopped by New Earth's Superman. Superman lashes out and accidentally hits New Earth's Superman. He apologizes but flees at the sound of New Earth's Lois Lane. Later, Lois Lane meets Superman in JSA headquarters, and asks him what happened to Lois Lane of Earth-22. Superman tells her the story of how his wife died. Sandman, Superman and the JSA learn that Gog is on the verge of permanently rooting himself into the Earth's core, which would result in the planet's destruction if he ever leaves. Realizing their only choice is to kill Gog and remove his head, Superman and the JSA confront Gog, and with the help of Gog's disillusioned followers achieve their goal. Superman has Starman open a Stargate to the Source Wall, where he places Gog's head. Superman then asks Starman, who has a map of the Multiverse on his costume, to send him back to Earth-22, to just before the bomb that destroyed Kansas went off.
