―Ray's true colours after being exposed as a mutant
Ray Thompson was the mascot of the Justice Guild of America. In reality, he was a being possessing supernatural powers.
The JGA fought in a nuclear war that cost all of their lives and led to the destruction of most of their planet's world. Ray was among those that survived, having been unfortunately mutated into an abominable, inhuman creature, and had developed vast psychic powers from the nuclear fallout. He used his newfound powers to recreate the world in which he lived and "resurrected" his heroes.
When part of the Justice League entered the time-stream of the alternate Earth, they worked alongside the JGA to defeat schemes planned by the villainous Injustice Guild. Hawkgirl, while ending a battle of this manner, stumbled upon the graves of the "real" JGA, becoming suspicious as to what was really going on. After a series of events, an enraged Ray revealed his true form and his plot (which was simply to recreate the world he once knew). The JGA learned that they were simply Ray's "creations", and not the true heroes, so in a true act of nobility, they did battle with Ray and "died" once again to save their world, however real it may have been.
Powers and abilities
Reality Alteration: After being exposed to radiation, Ray's brain mutated, developing the psychic power of altering reality in order to match his every whim. However, this was a limited illusion, that was in reality only a façade. He created a library, but all the books were filled entirely with blank pages. He only covered up the war-torn subway stations with a simple brick wall hidden on the other side of a basement door. Ray had even left the graveyard where the Justice Guild had been buried untouched, instead of hiding it. The Justice League easily noticed that the citizens were behaving strangely: the ice cream driver never stopped to serve anybody, there were only two police officers in the entire city, and threats popped up out of nowhere whenever they came too close to uncovering the truth.
