Deathstroke was a founding member of Lex Luthor's Secret Society of Super Villains in the "Infinite Crisis" storyline. He was seen in "Infinite Crisis" #1, hiding in a warehouse south of Metropolis waiting to ambush the Freedom Fighters with several other members. The battle did not last long, and by the end, Deathstroke had killed the Phantom Lady. Slade is also the one who landed the final stroke on Uncle Sam by shooting him in the back (and leading to his apparent death).
