Green Lantern #19

In "L'ennemi cosmique numéro un," Green Lantern Hal Jordan teams up with Tomar-Re and newly minted Green Lantern Charley Vicker to dismantle a hidden fortress on a prison planet, where a dangerous band of alien criminals—led by the Earth-born Al Magone—are using a captured alien robot to power Mini-Nucleo weapons. These weapons can nullify Green Lantern energy, making them deadly across the cosmos, and the mission becomes a race to stop a wave of assassinations before more lives are lost. With help from fellow Corps members Katma Tui, Chaselon, Zborra, and Stel, and the wisdom of the Guardians of the Universe, the team must outwit a conspiracy that threatens the entire Corps.
