Synopsis for Superman and the Flash: "Race to Save Time"
Superman and Flash, on a race to save the universe, are captured by the Anachronids and taken to the edge of the Phantom Zone. They find themselves under the vacillating light of the Vortex Sun and prisoners of Phantom Zoners Jax-Ur, General Zod, Kru-El, and Prof. Vakox, who are using the Anachronids to escape the Phantom Zone.
Jimmy Olsen is lost in time, and escapes from a barrage of Roman arrows, before appearing in the magistrate of the Spanish Inquisition. Time is out of joint.
The Zoners tell the heroes that the Anachronids are causing the time disruption, and will rupture the barrier between the Zone and the rest of the universe; freeing them while destroying Earth's solar system. Though the Vortex Sun is currently red for the moment, Superman and Flash use their willpower to draw the Green Lantern Medallion and break free and defeat the villains. What began as as a galactic footrace ends with the two heroes crawling in the dirt to shut off the Anachronids. And the Flash wins the race.
After the Vortex Sun goes yellow, Superman uses his newly returned powers to knock out Kru-El and smash the machine that created the Anachronids, inadvertently freeing Jimmy Olsen and returning the timestream to normal.
