Mercy went through several papers with Luthor, including one revealing Speedy had left his hospital bed. Moments later, they were startled by a rocket, fired from an adjacent rooftop. Both made it safely under Luthor's desk in time.

Mercy was concerned with Luthor's safety, but he insisted on getting a briefcase from his vault first. She then led him to the car parking lot. Speedy confronted them, and ordered them to disarm. Instead, Mercy attacked him. The fight went on for some time, with Mercy on the offensive. Speedy beset her with several types of weapons, both ranged and close combat, and eventually defeated her. He coiled LexCorp detonation cord around her cybernetic arm and blew it off, sending Mercy into a nearby car.[8]
