Nightwing
Due to a crisis of conscience, Dick adopts the new villainous persona of Renegade in order to infiltrate Lex Luthor's Secret Society of Super-Villains. This ruse includes Nightwing aligning himself with his long-time enemy Deathstroke in order to track the manufacturing and distribution of Bane's venom serum and to keep tabs on the Society's activities in Gotham and Blüdhaven. He also begins training (and subtly converting) Deathstroke's daughter, Ravager.
