James Gunn Plans Peacemaker Batman Fight in DCU

James Gunn, co-head of DC Studios, expressed interest in seeing John Cena's Peacemaker face off against Batman within the new DC Universe (DCU). This idea was discussed during a panel at CCXP Mexico 2025, where Cena confirmed Gunn's desire for the fight while Gunn humorously suggested Batman would likely win. Although the Batman role and casting details remain unannounced, a Batman movie titled The Brave and the Bold is in development, directed by Andy Muschietti. Peacemaker Season 2, which continues the story of Christopher Smith and connects to other DCU projects like Creature Commandos and Gunn's Superman film, is set to premiere on HBO Max in August 2025. The upcoming season will feature a returning cast and new characters, including appearances by Justice Gang members Hawkgirl and Green Lantern Guy Gardner. While no official confirmation exists about the fight happening, the prospect excites fans and adds anticipation for the expanding DCU narrative.
