Green Lantern: Beware My Power

Plot

Former Marine and Medal of Honor recipient John Stewart, struggling with civilian life after serving as a sniper in Afghanistan, witnesses Ganthet's spaceship crash nearby. Ganthet dies of his injuries, and the Power Ring he carries — previously owned by Hal Jordan — attaches itself to Stewart's finger. The ring flies Stewart up to the Justice League Watchtower, where he meets Green Arrow, Martian Manhunter, and Vixen, who were monitoring a disturbance in space. With the Guardians of the Universe unresponsive and Jordan's apparent death, Stewart and Green Arrow use Ganthet's repaired ship to travel to Oa, which they discover in ruins and the Green Lantern Corps slaughtered. They encounter Thanagarian warrior Shayera Hol, who indicates security footage showing a Rannian ship docking at Oa just before the attack.

Shayera explains that the Thanagarian-Rannian war had briefly ended, with Jordan overseeing a joint project using Zeta-Beam technology to benefit both planets. The experiment was a success at first, then went haywire, transporting Thanagar into Rann's atmosphere, upsetting the ecosystem of both planets, restarting the war, and apparently killing Jordan and thousands of Thanagarians and Rannians. Shayera accuses Rann of sabotaging the experiment and attacking Oa, but Stewart and Green Arrow insist they investigate further.

The team travels to a Rannian military outpost that was raided by Thanagarians, where they encounter Rannian hero Adam Strange, presumed deceased but teleported at random by Zeta-Beams' attraction to him. Strange denies that Rann attacked Oa and leads them to Rannian High Command, engaged in a battle with Thanagarian forces. Rannian Captain Kantus reveals that Rannian scientist Sardath, Strange's father-in-law, has converted the Zeta-Beam project into a doomsday weapon to destroy Thanagar. Shayera and Strange review footage from past attacks and discover that a third party has been impersonating both Rannian and Thanagarian ships to further the war.

Retracing the trajectories of the imposter ships, the team discovers a base hidden inside an asteroid, where they battle the Yellow Lanterns, along with a group of galactic assassins including Lord Damyn, Kanjar Ro, and Despero, before being captured by their leader Sinestro. Jordan is revealed to be alive, having released his ring and been taken prisoner after Sinestro sabotaged the Zeta-Beam experiment. They escape as Sinestro and his Lanterns attack Rann to find the location of Sardath's doomsday weapon. Using the Zeta-Beams, Sardath teleports them to his secret base, but Sinestro and his Lanterns follow and attack. During the battle, Stewart reluctantly kills Sinestro and Jordan brutally kills two of Sinestro's assassins leaving Green Arrow and John Stewart suspicious of his actions.

After obtaining the Zeta-Beam data, Jordan suddenly kills Sardath; he reveals that, when he was captured, Sinestro had infected him with the Parallax Entity, corrupting him. After Sinestro had destroyed the Green Lanterns, Jordan had claimed all their rings for himself, enhancing his power to a godlike state. With the Zeta-Beam technology, Jordan intends to destroy both Rann and Thanagar in a quest to end conflict across the galaxy and reshape it in his own image.

Stewart and Jordan battle until Green Arrow is forced to shoot and kill Jordan. They are unable to stop the weapon from firing, but Strange flies in the path of the Zeta-Beam, teleporting it and himself to parts unknown. Stewart and Green Arrow return to Earth, and Stewart sends Jordan's rings to their new wearers to rebuild the Green Lantern Corps. Shayera departs from Earth, in Ganthet's spaceship, promising to Green Arrow and Stewart they would meet again soon knowing Rann and Thanagar will need the new Green Lanterns and the Justice League to help rebuild both worlds when a ceasefire is ordered. Stewart proposes dinner and a toast to "absent friends" to Green Arrow, to which he replies "and maybe a few new ones".
