- Green Arrow remembers how the League used to be and how much he enjoyed that more innocent time as he fights Hunter, Dr. Impossible, and Neon Black in the Watchtower. Meanwhile the rest of the League fight Tender Mercy and Chair on Blackhawk Island and meet Congorilla and Starman there. Red Tornado aids Green Arrow in routing the three villains. The League then begins to separate for various personal reasons, leaving only Batman, Donna Troy, Congorilla and Starman to defeat some other villains who were working for Prometheus. The five villains assemble the machine pieces they've gathered and activate it, peering into the various worlds of the Multiverse.
Most of the cameos appear on pages 30 and 31, where the villains look at the Multiverse. Mr. Atom is referred to as Mr. Atomic in the story. "All Along The Watchtower" is the title of a song by Bob Dylan, a cover of which was done by Jimi Hendrix and others.
