Together with Joker, Frost follows Harley Quinn and the Task Force X to Midway City where they hijack the helicopter supposed to retreive Amanda Waller. When the Squad and Waller head towards a roof waiting for their helicopter, Frost and Joker instead open fire, Frost using the helicopter's minigun. They force the squad to search for cover and allow Harley to jump off the roof and grab the rope hanging from the helicopter. They then fly off in their attempt to escape the city.
