However, it successfully recruits the populist, astute Green Arrow as its political conscience; he puts the role of Cadmus in perspective for the League, preventing it from succumbing to the temptation that created the Lords. Luthor hacks the Justice League Watchtower to attack Cadmus headquarters, with extensive collateral damage. As the public turns against it, the League decommissions the Watchtower and surrenders as a good-faith gesture (except for Batman, who wants to clear the League's name himself). Cadmus, however, decides to retaliate, sending Galatea (a clone of Supergirl) and an army of genetically engineered metahumans to destroy the Watchtower and kill the rest of the League on board. Fortunately the League subdue the clones and Supergirl renders the rogue Galatea catatonic. When Batman finally convinces Waller that Luthor is responsible for the attack, they confront him in his Lexcorp offices, only to be beaten back by Lex, demonstrating unnatural speed and strength. The rest of the League arrives to save them, learning that Superman's old enemy Brainiac (last seen in a battle with Darkseid) had been hiding in Luthor's body for many years. Brainiac, resident in Luthor, creates duplicate androids of the Lords in the "Justice League Unlimited" episode "Divided We Fall". He adds an android duplicate of the Flash, in a costume nearly identical to that of comic-book villain Zoom, to distract the League from his (and Luthor's) goal of universal domination. The androids fight the League, playing on its worst fears: Superman becoming a Justice Lord, Green Lantern and Hawkgirl's failed relationship and her pariah status on Earth and Thanagar. Only Flash seemed unaffected by his replica's taunts due to his overly optimistic nature, and the androids were quickly destroyed, though the group of androids was merely a delaying tactic on the part of the Brainiac/Luthor entity. The growing fear that the League might become the Lords reaches a climax in this episode, when the Flash exceeds his maximum speed (vanishing into the Speed Force) to destroy the link between Brainiac and Luthor. With Flash supposedly dead, and Luthor at his mercy, Superman is put in exactly the same position as his Justice Lord counterpart, but resists the temptation and refuses to kill Luthor. Proclaiming that he was his own person & not a Justice Lord. J'onn then senses Flash's presence, and the League successfully pulls him back from the Speed Force before he can vanish completely, saving his life and avoiding the path of the Justice Lords.
