Roll call: The Flash, Superman, Wonder Woman, Green Lantern, and the Atom
This yarn kicks off with the Flash being kidnapped! Who did such a thing? The culprits turn out to be some scientists from the planet Sfarl. They have been teleporting themselves involuntary across the galaxy and they would very much like to stop, please.
The catch is as soon as they leave a planet, it blows up for some reason, so if the JLA could do them a solid they would appreciate it. The JLA manages to get sent to the next planet on the list, where they encounter Kraad. Why is he doing this?
Seems the scientist's teleporting is needed to power his doomsday weapon. A weapon he promptly uses on the JLA, blowing them up. All save for the Atom, who's suit saved him.
Finding Green Lantern's Power Ring, he manages to restore his teammates, sort of. Wonder Woman gets brought back fully, but the guys get merged. Despite this, they manage to stop the Conquror's plans and take out his doomsday weapon and get themselves restored.
