In the 1960s, a nuclear war destroyed most of the world, including Seaboard City. The Justice Guild was killed in battle. The fallout mutated Ray Thompson into a being able to warp reality. He used this power to recreate Seaboard City the way he always knew it.
Green Lantern, Hawkgirl, Flash and J'onn J'onzz were transported to Seaboard City's dimension, and briefly fought beside the revived Justice Guild. Suspicious of events that seemed to be too coincidental, Green Lantern and Hawkgirl exposed Ray's illusion.
The other civilians, which had been in a suspended form during the animation, finally had the chance to rebuild their fair city.
- Seaboard City's location is not revealed, but it appears to be on the West Coast.
- Designs for Seaboard City were repurposed as Fawcett City for the Justice League Unlimited episode "Clash".
