Justice League of America #39

When a panicked Peter the Puffer Fish warns Aquaman of an alien invasion, the sea king rallies Wonder Woman, Green Lantern, Flash, and J’onn J’onzz to face the threat of Starro the Conqueror—whose mind-controlled starfish lieutenants are already spreading chaos across Earth. With Superman and Batman unable to join, the heroes split up to confront the growing menace, each team racing against time to stop the alien starfish’s plan.

In this 1965 tale from *Justice League of America* #39, Wonder Woman and J'onn J'onzz race to rescue a group of Earth scientists held captive by a rogue Starro lieutenant. As they uncover the alien’s chilling ability to share stolen knowledge—and now, devastating nuclear power—the heroes must outthink a foe whose strength grows with every mind it consumes.

In "Starro vs. the Flash!" from Justice League of America #39 (1965), the Flash races against time in Happy Harbor, where a Starro duplicate has taken over and the townspeople lie under its mind control—except for a single defiant teenager. With the help of a mysterious ally, Flash battles the third Starro lieutenant, uncovering the location of the real alien threat, and makes a surprising decision about who will stand beside him in the final confrontation.

When Starro's mind-control powers threaten to overwhelm the Justice League, Flash and Green Lantern make a crucial discovery: Snapper's immunity comes from being coated in lime. With quick thinking and a few well-placed barrels, the heroes turn the tide—leaving Starro trapped and the JLA’s newest trophy.

When the Justice League suddenly loses their powers, Flash tracks a bizarre theft—catfish and cicadas spirited away across Europe—leading the team to suspect a sinister quest for immortality. As they investigate long-lived creatures, they're ambushed by Amazo, who steals their abilities and takes them to Professor Ivo’s lab, where the secret serum is nearly complete.
