In "Crisis on Earth-One!", a dangerous alliance of three villains from Earth-1 and three from Earth-2 conspires to commit crimes and vanish across dimensions, evading justice by hiding on the opposite Earth. With the Justice League of America trapped in their own headquarters through a mystical ambush, the heroes call upon their older counterparts—the Justice Society of America—to take their place and stop the escalating threat.

In "Crisis on Earth-Two!", the Justice League of America and the Justice Society of America find themselves caught in a cosmic trap when they’re mysteriously whisked from their respective Earths into floating cages in space. With their worlds under siege and their allies in danger, the heroes must break free, unite across dimensions, and confront a dangerous coalition of villains before it’s too late.

In "Crisis on Earth-Three!", the Crime Syndicate—bored with their reign of tyranny on Earth-3—seek fresh challenges after Ultraman’s accidental exposure to Green Kryptonite unlocks unpredictable new powers. When the Syndicate invade the JLA’s Earth, the heroes seem to gain the upper hand—until the villains teleport them to Earth-3, where their dominance is absolute. Now, with the JSA on Earth-2 in their crosshairs, the stage is set for a battle that could reshape the multiverse.

In "The Most Dangerous Earth of All!", the Justice Society of America is ensnared by the Crime Syndicate in a cunning dimensional trap, forcing the Justice League to confront the villains on Earth-2. With the fate of multiple worlds hanging in the balance, the JLA must outwit the Syndicate’s ruthless tactics before the interdimensional prison collapses—trapping them all.

In "Earth -- Without a Justice League!", the Johnny Thunder of Earth-One seizes control of the Thunderbolt after his Earth-Two counterpart accidentally summons the entity to meet him. With the power of the Thunderbolt, he alters history by preventing the Justice League from ever forming, setting off a chain of events that reshapes the heroes' legacy. Now, he uses the past to forge a new kind of team—one built on chaos and defiance—to challenge the JSA on Earth-One.

In "Crisis on Earth-A!", the Justice Society of America faces off against the Lawless League and three monstrous beings born from the twisted power of Johnny Thunder of Earth-One. As the battle reaches its peak, Johnny surrenders, urging the Thunderbolt to undo the chaos by resetting time—before any of it ever happened. But when the moment comes, the Thunderbolt hesitates, catching Johnny just as he begins to wonder if a counterpart on Earth-One still exists.

In "Crisis Between Earth-One and Earth-Two!", the sudden, unexplained teleportation of individuals—including Blockbuster and Solomon Grundy—between two parallel Earths throws both worlds into chaos. As the Spectre uncovers the truth, he realizes the arrival of the Anti-Matter Man is behind the rifts, threatening to destroy both realities if not stopped.

In "The Bridge Between Earths!", the Justice League and Justice Society face an interdimensional crisis when a malfunctioning space-warp device created by Ray Palmer’s assistant tears open a rift between realities. With the Anti-Matter Man threatening to consume both worlds, Ray Palmer and the Spectre must work together to restore balance—Ray shutting down the machine, and the Spectre wielding his divine power to reposition the Earths in time and space.
