Chapter Summaries

Clark struggled with doubts about his Kryptonian origins while Lex Luthor unleashed a spatial rift on Metropolis and provoked an invasion of Gambol. After Lois exposed Lex’s role in both disasters, Clark regained his resolve and took off from the Kent farm.

• Lex Luthor activated the Pocket Universe portal’s reversal protocol, sending a spatial rift toward Metropolis and destroying much of the city.

• Lois hijacked the television broadcast and revealed evidence that Lex had caused the Metropolis disaster and funded the war in exchange for territory.
• Clark hugged Martha, exchanged a determined look with Jonathan, and blasted off from the farm.

Clark returned to Metropolis, saved civilians from a collapsing building, and joined Mister Terrific as Luthor’s forces arrived. He sent Mister Terrific to protect the people in Gambol, then fought Ultraman and The Engineer, who pinned him down and tried to force nano-tendrils into his mouth.

• The Engineer ambushed Clark, pinned him to the ground, and tried to force nano-tendrils into his mouth.

Ultraman and the Engineer overwhelmed Clark, with Ultraman using Lex Luthor’s combat-command system to land a devastating blow before the Engineer covered Clark in nanobots. As the nanobots invaded Clark’s face and lungs, Pero left his collapsing penthouse with Krypto and headed toward the stadium.

• Pero noticed the purple spatial rift destroying his neighborhood, then grabbed Krypto and flew toward the stadium.
• The Engineer shot Clark with an energy cannon and sent nanobots into his nose, mouth, and eyes to suffocate him.

Clark tried to escape the Engineer’s nanobots by flying toward space, but Ultraman and the Engineer attacked him and the three fell back to Metropolis. Lex Luthor watched them crash into the street and furiously berated his subordinates for failing to fly away.

• Clark launched himself toward space, hoping its cold and lack of oxygen would stop the nanobots, while Ultraman and the Engineer pursued him.
• The Engineer clung to Clark and invaded him with nanobots as Ultraman repeatedly punched his face, and the three continued rising through the atmosphere.

• Ultraman kicked Clark and the Engineer away in an attempt to save himself, but all three struck the ground and landed motionless in a crater beneath the street.
• Lex Luthor watched the crash on the surveillance feed, then shouted at Ultraman and the Engineer for not using their ability to fly.

Clark woke in the Metropolis sewers and learned that Ultraman was Lex Luthor’s clone of him. Pero arrived in time to stop Ultraman’s attack and began berating Clark, then turned his attention to Lex Luthor with a taunt about cloning and Krypton’s future.

• Pero appeared with Krypto and caught Ultraman’s punch effortlessly, startling Lex Luthor and relieving Clark.
• Pero scolded Clark for losing to a clone and suggested Lex Luthor should handle the task of perpetuating Kryptonian bloodlines.

Pero overpowered Ultraman with a single punch, then cleared the collapsed sewer ceiling and destroyed Lex Luthor’s surveillance equipment. He and Clark prepared to test whether Ultraman shared Clark’s powers.

• Pero ripped the microphone and speaker from Ultraman’s armor and sent Krypto to destroy the circling drones.
• Pero told Clark he wanted to test whether Ultraman could absorb yellow sunlight, heal quickly, and grow stronger, and Clark joined him to watch.

• Pero sensed someone approaching, and Clark explained that his cousin had arrived on Earth after being trapped in the Phantom Zone.
• Kara crashed into the Fortress of Solitude, staggered toward Clark, and asked why he had taken the fortress doors down.

Kara met Pero at the Fortress of Solitude and learned that he came from a parallel universe, then eagerly examined his teleportation device. She reunited with Krypto, whom Pero stopped from entering his room, and he threatened to throw the dog into the Sun if it chewed anything.

• Clark told Kara that Pero was another Kryptonian, and Kara excitedly asked how he had survived Krypton's destruction.
• Pero explained that he was not from Kara's universe, and Kara realized he came from a parallel universe.
• Pero showed Kara his ring-shaped teleportation device, and she eagerly inspected its technology.
• Kara called for Krypto, and Pero caught the dog before he could enter his room.

Pero left Clark’s universe through the portal with Kara, who wanted to explore another Earth. They arrived in a devastated field of debris in space, and Pero realized the wreckage was Earth.

• Kara asked to travel with Pero, and Clark worried about her entering an unknown universe.
• Kara insisted she was ready to go, and Pero created a golden phantom as an anchor for Clark before opening the portal.
• Pero and Kara said goodbye to Clark and stepped through the portal while Clark stayed behind with Krypto.
• Pero and Kara emerged in space among fragments of wreckage, including a damaged Batman cowl.
• Pero identified the debris field as Earth, leaving Kara shocked by the sight of the destroyed planet.

Pero and Kara found the remains of a destroyed Earth and glimpsed a phantom Earth showing a battle between Superman and General Zod. Suspecting the planet had been destroyed when universes collided, Pero tried to reverse time by flying around its reignited core, and the scattered debris began to reassemble.

• Pero showed Kara a torn bat cowl among Earth's remains, and she realized the planet had been shattered like Krypton.
• A phantom Earth flashed past them, revealing Superman fighting General Zod in a city before both combatants noticed Pero and Kara.

• Pero used Heat Vision to reignite the planetary core, then flew around it at immense speed in the opposite direction.
• Kara watched the debris converge and form the outline of a planet as the shattered Earth began piecing itself back together.

Pero restored Earth by reversing time, then brought Kara back to the moment before the planet’s destruction. Barry Allen, revived after dying in the Speed Force, tried to find his younger self and save Superman, but Pero and Kara’s arrival threw the battle into chaos.

• Pero reversed time until Earth and the solar system were restored, then told Kara they would return to the moment of Earth’s destruction.
• Barry Allen remembered dying to a metal-covered monster in the Speed Force and realized he had returned to the battlefield.
• Barry searched for his younger self, suspecting he could become the monster, and resolved to save this world’s Superman.
• Four massive laser beams destroyed Kryptonian spaceships above the battlefield, bringing the fighting to a halt.
• Kara and Pero descended onto the battlefield, and Barry despaired that their arrival had changed events beyond his understanding.

Pero stopped Zod from stabbing the first Kara to seize the Life Codex, and Kara from the Gunn Universe struck Zod and defended her father’s actions during Krypton’s destruction. Zod recognized her as Kara Zor-El and was left confused about the other Kara.

• Zod grabbed the first Kara and tried to stab her to obtain the Life Codex, but Pero stopped him and snapped his arm blade.

• Kara told Zod that Zor-El had saved Argo City and tried to lead its people to safety.
• Zod recognized the second Kara as Kara Zor-El, then looked at the first Kara and wondered who she was.

Two versions of Kara and two versions of Barry converged on the battlefield, leaving General Zod confused and the future Barry convinced that his time-travel changes had doomed the universe. Zod tried to attack, but froze under the intimidating gaze of the armored man who had broken his blade.

• The imprisoned Kara recognized the other Kara’s family crest and hurried to meet her, while Gunn’s Kara greeted her with enthusiastic chatter.

• Zod roared and moved to seize Kara, but stopped when he felt the armored man’s gaze and sensed his overwhelming power.

• Zod trembled as Pero's presence drained his courage.
• Pero listed the missing Wonder Woman, Aquaman, Cyborg, and Justice League as signs that Barry's universe was malformed.
• Barry hoped Pero could restore the original timeline, but Pero said Barry could no longer go back and the universe was destined to collapse.
• The younger Barry suggested Pero was a traveler from another parallel universe, and Pero confirmed his guess.

Pero helped old Barry return to the past to correct his mistake, then stopped the collapsing world from being erased by opening gates between countless worlds. Kara and the others survived as the worlds converged, and Pero set out to explore the newly connected realms.

• Pero knocked Zod into space, then opened a rift through time for old Barry to return and correct his mistake.
• Old Barry embraced young Barry, gave him advice, and ran into the time tunnel as the world began to dissolve.
• Kara began to disappear, but Pero froze the collapsing world and opened gates connecting countless realms.
• People across many worlds saw the gates open, while Kara solidified and survived the erasure.
• Pero descended and walked toward the gates, ready to travel between the connected worlds.
