| Synopsis | Heroes gather because some unknown force is disrupting the fabric of time and pulling the Earth out of orbit. Volcanoes explode, dinosaurs rampage, and heroes from all times pop up everywhere. Scientist-heroes - the Atom, the Flash, Rip Hunter - fly to an orbiting spaceship and battle gold robots. Lois Lane, the Creeper, Challengers of the Unknown, and others fly to the Rocky Mountains to crack a big green alien box. Metal Men and Teen Titans contain riots and quash Vikings and Nazis. Space heroes - Adam Strange, Space Ranger - need the magic heroes - Phantom Stranger, the Spectre - to hold a seance and channel energy? to return the Earth to its orbit. Lois Lane and Angel O'Day enter the big green box, dodge robots, and pull wires. Everything snaps back to normal. Clumsy Angel O'Day cries with happiness. "It's the first time I've ever been happy about breaking something!" |

| Notes | Features almost every character who ever appeared in Showcase. A later letter column stated this issue is "just for fun", so non-canonical, not a real DCU story. Letters page in this issue says that Nightmaster appears on page 8, although he does not seem to be in the issue at all. |
| Synopsis | The letters column tells how the creators - all fans of Showcase - pulled the book together. It then gives brief biographies and cites issues for the 60 super-stars, as well as where they appear in the main story. |
