The irreverent superhero series Peacemaker, created by James Gunn, wrapped up its second season on HBO Max in October 2025, delivering a blend of action, humor, and world-building that ties directly into the broader DC Universe (DCU). Starring John Cena as the titular antihero, Season 2 expanded the story of Christopher Smith while introducing new characters and connections to upcoming DC projects.
Season 2 Overview
Peacemaker Season 2 premiered on August 21, 2025, with the episode The Ties That Grind, and concluded with the finale Full Nelson on October 16, 2025. The season explored Chris Smith’s internal struggles and moral dilemmas, including encounters with alternate versions of himself, adding complexity to the show’s comedic yet heartfelt tone.
Expanding the DC Universe
One of the most exciting aspects of Season 2 is its integration with the larger DC Universe. The finale introduced “Salvation”, an alternate dimension designed to imprison metahumans — a plotline that sets up connections to future films like Man of Tomorrow. Fans were also treated to a cameo by Nicholas Hoult as Lex Luthor, cementing the series’ role in the wider DC narrative.
Behind the Scenes & Cameos
James Gunn directed and wrote all episodes of Season 2 and even made a cameo in the finale during a Foxy Shazam concert scene. Filming ran from April to November 2024 and featured guest appearances from Nathan Fillion (Guy Gardner), Isabela Merced (Hawkgirl), and Frank Grillo (Rick Flag Sr.), among others. Gunn’s cameo marked his on-screen inclusion in the DCU, delighting eagle-eyed fans.
Fan Reception
While Season 2 was praised for its humor, character development, and DC connections, the finale drew mixed reactions. Some fans felt certain storylines were rushed, though Gunn acknowledged these critiques while expressing satisfaction with the creative choices.
What’s Next?
Currently, there’s no confirmed plan for a third season of Peacemaker. However, Gunn has hinted that the characters will continue to play roles in the evolving DC Universe. Upcoming projects like the Supergirl film, scheduled for June 26, 2026, are expected to explore cosmic storylines that intersect with the events of Peacemaker and other DC films, keeping fans eagerly anticipating the next chapter.
