Kal Kent, Superman from the 853rd Century saves Roy Harper from Vandal Savage's Rocket Red suit, which had been set on auto pilot to detonate in Metropolis, and programmed to defend it self from any opposition. A mob, driven mad by the Hourman Virus, mistrusts and attacks him, but Roy and the local authorities hold them off while Kal meets up with Lois Lane and they search for components to build a solar computer to contain the virus. Lex Luthor offers assistance but ultimately betrays them, as he too is affected by the Hourman Virus. Even though Kal's powers are fading one by one in the absence of the Super Sun of his era, he defeats Luthor's armored guards and escapes with Lois. Having failed to find the parts he needs and unable to enter the Fortress of Solitude, he resolves to go to the JLA Watchtower on the Moon.
