Lobo stole the rings from the Red Lanterns and pits Atrocitus, Zilius Zox and the rest of the Red Lanterns against Batman, Superman, and Wonder Woman in order to get a score. After Lobo unlocked the Spider Gauntlet's power, the Justice League and the Red Lanterns must team up to defeat him.

While the Justice League is away on a mission, Plastic Man is not only left in charge of the Watchtower, but also of Krypto Superman's not so ordinary dog.
