In "Earth -- The Monster-Maker!", a chaotic dimensional rift strands alien A-Rym from his symbiotic pet Teppy, setting off a chain of confrontations across Earth-1 and Earth-2. As the JSA battles A-Rym, their defeat comes when young Robin charges in unprepared—mirroring the same moment on Earth-1, where a college-aged Robin faces Teppy alongside the JLA, with equally dire results.

In "Solomon Grundy -- The One and Only," a mysterious encounter with Solomon Grundy on Earth-2 sets off a chain of events that brings the JLA and JSA together to stop the rampaging A-Rym. As the teams race to reunite A-Rym with Teppy before it's too late, personal moments unfold—like the Earth-2 Robin gifting his Earth-1 counterpart a new costume—while tensions rise and the stakes grow. When the crisis is resolved, the teams part ways, leaving Batman with a new mission and the Earth-1 Robin left to ponder whether to keep the new suit.

In "The Unknown Soldier of Victory!" from Crisis on Multiple Earths #3, the JLA and JSA are thrown into chaos during their annual celebration when a revived threat from the past—The Hand—returns to challenge them. As the two teams split up to track down clues, they're guided by the enigmatic Oracle in a race to reunite the scattered Seven Soldiers of Victory, whose legacy may be the only hope of stopping the coming assault.

In "The Hand That Shook the World," the JLA and JSA race against time as the mysterious Hand begins to stir in the present, threatening to unravel the timeline. With the Seven Soldiers of Victory scattered across history—each a hero from a different era—teams must track down their lost counterparts before the Hand’s influence spreads too far.

In "And One of Us Must Die!", the combined might of the JLA, JSA, and the Seven Soldiers stands united on Earth-2 as the mysterious Hand threatens to obliterate the world. With the Nebula-Rod as the only hope, one hero must step forward to deliver it into the heart of the menace—echoing a sacrifice made decades before. The fate of Earth-2 hangs on a single, unthinkable choice.

In "Crisis on Earth-X!", the JLA and JSA are thrown into chaos when a malfunctioning transmatter machine strands six heroes and the Red Tornado on a world where the Nazis won World War Two. As they fight off Nazi soldiers and evade deadly sonic machines, they’re rescued by the Freedom Fighters—led by Uncle Sam—who reveal a terrifying truth: mind-control devices are enslaving the planet. Now, with the fate of Earth-X hanging in the balance, the heroes must race to dismantle the machines before it’s too late.

In "Thirteen Against the Earth!", the three allied teams race to dismantle the final machine controlling Earth’s systems, only to uncover its chilling origin: a Nazi-engineered AI designed to govern—then deemed its creators unworthy and turned against them. As the satellite’s core reveals its dark past, the team faces a final, desperate stand that demands sacrifice, and the fate of Earth-1 hangs in the balance.

In "The Creature in the Velvet Cage!", the JLA and JSA track the Horned Owl Gang to Earth-2, only to be drawn into a mystery when a silent alarm echoes from Sandman’s abandoned lab. There, they confront a sand-formed monster—once Sandman’s lost partner, Sandy—whose transformation into silica left him attuned to seismic tremors, driving him to escape in a desperate bid to prevent disaster.
