Back on Earth, Aqualad and Blue and Green Beetle take on Black Beetle on board the Reach ship. Black Beetle destroys Green's scarab, but Blue destroys Black's. However, he learns that Black Beetle has set an endgame in motion. Back on Rimbor, the council reconvenes and after some persuading, agree to reassess the case, and eventually release the League. Around the world, twenty Reach devices begin to damage the Earth's magnetic field, causing various types of natural disasters. Every hero is called in to split into teams of two, each duo carrying one of twenty devices provided by Lex Luthor that will shut down the machines. They succeed, but Jamie discovers a twenty-first machine in the Arctic. Flash and Impulse arrive to find that it has already gone into "chrysalis" mode and will soon destroy Earth; the two, directed by Luthor, use their speed to create a vortex that draws off the device's energy but need a further boost in order to succeed. They are soon joined by Kid Flash, but Wally's slower speed makes him a target for stray energy discharges which apparently cause him to disintegrate. The machine is shut down and Flash tells a distraught Artemis that Wally said he loved her before vanishing. The Justice League arrive back on Earth to be greeted by the Team, who inform them of Wally's disappearance. July 4: The world is finally free of the Reach, who are set to face trial for their actions. G.

As the tensions between the two groups begin to come to the fore, Ra's al Ghul notices the glamour charm on Tigress's neck and exposes her as Artemis, leading Deathstroke to execute both her and Kaldur. However, a hologram of Aqualad then plays which reveals to the Reach the extent of the Light's manipulations, leaving their alliance in tatters. Aqualad and Artemis suddenly rise, and as 'Deathstroke' turns out to be a disguised Miss Martian, the Team and Kid Flash make their entrance, leading to an all-out battle. In the midst of the chaos, the Reach ambassador and the Brain are captured, while Aqualad defeats Black Manta and Black Beetle mortally wounds Ra's al Ghul. However, Ubu rescues Ra's (pledging that he will be revived), Black Beetle escapes with the Reach Scientist, and Vandal Savage summons Klarion to elude the Team. In the aftermath of the battle, Nightwing insists that Aqualad take over leadership of the Team, while Savage ousts the League from the War World by defeating Black Lightning, Black Canary and Captain Marvel; then uses it to flee into space. On Earth, the League present the public with proof of the Reach's duplicity, and Black Beetle assumes control of the alien fleet, swearing to destroy the Earth now that it is of no further use to them and before the Green Lantern Corps and Guardians of the Universe arrive.
