leader of the Society, went with several villains (including old Titans and Doom Patrol foes and Brotherhood of Evil members Monsieur Mallah and Brain) to drop Chemo, another fellow villain who appeared to be a nearly brainless monster made of pure energy and radioactive chemicals, on Blüdhaven, killing over 100,000 people. Slade gave the explanation to the Brotherhood that Nightwing should be made to believe that he can never go home again. Nightwing took the first of his revenge by bursting in on Deathstroke and Rose's training session, revealing to the latter that the kryptonite that Deathstroke had implanted in place of her missing eye was radioactive and deadly to humans as well as to Kryptonians (as revealed by Luthor's old possession of a kryptonite ring that had forced him to transfer his brain to a cloned body). Angered, Slade went after Nightwing with a grenade, only to have Rose try to stop him. Amid the smoke of the resulting explosion, Rose fled, telling her father that she hated him. Nightwing disappeared as well, but not before leaving a note for Slade warning him that he would be back to make him pay for Blüdhaven. At the climactic Battle of Metropolis at the conclusion of Infinite Crisis, Slade was confronted by Batman, Robin and Nightwing. During the struggle, he was questioned regarding his motives for aiding the Secret Society. His claims of monetary motivation were deemed unsatisfactory; Batman accused him of having forsaken his code of honor, and Nightwing said it was because his family had abandoned him. Enraged, Slade said that was because of Nightwing, and that it was always because of him, before Batman told him to take responsibility for his actions and he was rendered unconscious. One Year Later Slade appears in the Green Arrow series after the one year jump in DC Comics' storylines. Apparently in hiding, he nearly murders a crony of several Star City businessmen who want to hire him for a murder. Before finishing his violent refusal, he asks the name of the target. When informed that it was to be the mayor of Star City, Oliver Queen (whom Deathstroke knows is secretly Green Arrow), he spares the lackey and decides to take the job. However, things do not quite go according to plan, with Green Arrow using the resources of both his identities, trapping him within a ring of armed National Guardsmen.
