The story opens on the doomed planet Krypton, moments before its cataclysmic destruction. Inside Jor-El's laboratory, the desperate scientist and his wife Lara place their newborn son, Kal-El, into a small spaceship bound for Earth, hoping to save him from the planet's imminent explosion. Amidst the chaos, an alien parasite known as Starro escapes containment in the lab and stows away on the ship. However, during the journey, Starro falls off the vessel somewhere in space, separated from Kal-El. The ship lands safely in Kansas, where the infant is found and raised by Jonathan and Martha Kent, who name him Clark. As Clark grows, he discovers his superhuman abilities and eventually becomes Superman, protector of Earth.

Years later, Clark Kent and Lois Lane live in Smallville with their young son, Jon Kent. Jon is a typical boy frustrated by his father's frequent absences and unaware of Clark's secret identity as Superman. On Jon's birthday, during a baseball game where his father is notably absent, Jon struggles and strikes out, feeling neglected. Later that night, Jon's latent powers unexpectedly manifest as heat vision, startling him. Clark and Lois finally reveal the truth: Clark is Superman, and Jon is his son, inheriting his powers. Overwhelmed but excited, Jon embraces this revelation.

To help Jon understand his emerging abilities, Clark takes him to Gotham City to meet Batman and his son Damian Wayne, the current Robin. Upon arrival, Jon meets Damian, who is immediately dismissive and teasing, establishing a tense but familiar rivalry. Batman and Superman discuss the recent loss of contact with the Justice League Watchtower, the satellite headquarters orbiting Earth. Batman reveals his concern about the Watchtower's status, prompting the two heroes to investigate after dropping Jon back home.

Meanwhile, the Justice League Watchtower has been struck by space debris, causing it to wobble dangerously in orbit. Superman rushes to stabilize it, saving the station from falling out of orbit. Onboard, Green Arrow investigates the source of the impact but is attacked by a monstrous creature controlled by Starro. Soon after, Batman and Superman arrive at the Watchtower only to be infected by Starro spores released by a possessed Martian Manhunter. The parasite begins to take control of the heroes aboard, turning them into mindless extensions of Starro's will.

With their fathers compromised, Jon Kent and Damian Wayne take matters into their own hands. The boys cram themselves into the spaceship that once carried baby Kal-El to Earth and launch toward the Watchtower, determined to save their fathers and the other heroes. Upon arrival, they face a harrowing scene: Justice League and Teen Titans members, including Batman and Superman themselves, are under Starro's control, transformed into hostile adversaries. The boys engage in fierce battles, pitting their emerging powers and skills against their possessed fathers and allies.

Damian uses a Kryptonite ring--a weapon he carries specifically to counter Kryptonians--to weaken Starro-controlled Superman. Jon, wielding his newfound heat vision and super strength, confronts Starro-controlled Batman. Their fights are intense and emotionally charged, as they struggle not just against enemies but against their own fathers' corrupted forms. Through these battles, Jon and Damian discover that Starro is vulnerable to heat and fire, a critical revelation that shapes their strategy moving forward.

The climax builds as Jon and Damian confront the giant Starro entity itself, a massive, starfish-like alien parasite dominating the Watchtower. Despite their combined efforts, the creature proves overwhelmingly powerful. Realizing that direct confrontation will not suffice, the boys make a grave decision: they will sacrifice the Watchtower by dropping it from orbit to destroy Starro once and for all. Before doing so, they evacuate Batman, Superman, and the other infected heroes onto escape ships to ensure their safety.

As the Watchtower begins its descent, Jon and Damian share a poignant moment, acknowledging the sacrifices heroes must make. The satellite crashes through Earth's atmosphere, engulfed in flames, obliterating the Starro parasite and ending the invasion.
