Justice League of America
While swimming the Atlantic, Aquaman comes upon Peter the Puffer Fish who tells him about a strange alien menace. He witnessed a gigantic creature named Starro land in the sea and use its powers to transform three starfish into oversized monsters that resembled Starro itself. Aquaman decides to call an emergency meeting of the Justice League of America, and activates the communicator contained within his A-Belt.
Wonder Woman is the first to receive the signal, and cuts short her date with Steve Trevor to respond to the call. She pilots her invisible robot plane to the Justice League’s cavern headquarters. Superman is the next to receive the signal, but he is too busy in outer space smashing meteors that threaten to enter Earth’s atmosphere. Likewise, Batman receives the distress call, but a crime wave in Gotham City prevents him from responding. Green Lantern is test flying a jet fighter, but sets it on autopilot, then flies off for the meeting. The Flash meanwhile, disrupts a powerful tornado, and then speeds away in response to the call. Fortunately, it is easy for detective John Jones to excuse himself, as the police chief tells him that he has earned himself some much needed vacation time. John hears the signal with his Martian hearing and flies off.
At Justice League headquarters, Aquaman tells the assembled team what he has learned of Starro. The Flash, as acting chairman for the League, delegates orders to each League member and gives them the locations of each of the Starro agent sightings. Green Lantern is to patrol the Rocky Mountains, while Wonder Woman and the Martian Manhunter investigate a sighting at Science City. Aquaman is to patrol the ocean depths, while the Flash himself will investigate a Starro’s presence in Happy Harbor, Rhode Island.
Green Lantern charges his ring, and begins patrolling the skies over the Rocky Mountains. He sees one of the Starro agents flying through the air and attack an Air Force jet bomber. The pilot of the bomber fights back, but the Starro is invulnerable to the jet's machine guns. The creature's tentacles snake inside and steal one of the atomic missiles from the bomb bay. The plane dives into a tailspin, and Green Lantern uses his ring to set it down safely. When he turns his attention back towards the Starro, he sees to his horror that the monster has detonated the atomic missile. Hal quickly envelops himself in a protective bubble and begins firing blasts of energy at the Starro's thorax. After several well-placed hits, the creature weakens and reverts to its normal state.
