Peacemaker

Christopher "Chris" Smith, also known as the Peacemaker, is a fictional antihero in the DC Extended Universe (DCEU) and DC Universe (DCU) media franchises, based on the Charlton / DC Comics character of the same name. Adapted for film by writer/director James Gunn, he is portrayed by John Cena. Smith operates as a vigilante who aims to achieve peace at any cost, which results in a 30-year prison sentence at Belle Reve Penitentiary. He is approached by the facility's warden and the director of A.R.G.U.S., Amanda Waller, to join a strike team called Task Force X aka the Suicide Squad composed of other inmates on an infiltration mission en route to the remote island of Corto Maltese. Upon turning on his teammates, secretly by under orders of Waller, and being incapacitated during the mission, he is nursed back to health by A.R.G.U.S. and sent on another mission immediately by her afterwards, now being tasked with accompanying a group of alumni from A.R.G.U.S. to prevent a world-threatening epidemic known as "Project Butterfly".
