John Cena is very serious about promoting his anti-hero Peacemaker. During the marketing phase of The Suicide Squad, the actor showed up in full costume at several events. With the spin-off series about his character from the film arriving in January, he is donning his Peacemaker suit once again to promote the project. He surprised fans at the San Diego Comic-Con Special Edition by walking on stage, in full costume, during the Peacemaker portion of the cosplay contest.
