Peacemaker Season 2 is set to premiere on Max on August 21, 2025. The series, starring John Cena, will be integrated into the new DC Universe (DCU) and have strong connections to the upcoming Superman movie.
Creator James Gunn has revealed that the "Quantum Unfolding Chamber" (QUC), introduced in Season 1, will play a central role in Season 2 and will also be featured in Superman. Expect appearances from Superman characters like Isabela Merced, Nathan Fillion, and Sean Gunn, along with other DCU figures. Gunn also teased a major cameo towards the season finale.
The new season picks up roughly two years after Season 1, with Peacemaker seeking recognition from the superhero community. The trailer confirms appearances from members of Superman's "Justice Gang," including Nathan Fillion's Green Lantern Guy Gardner and Isabela Merced's Hawkgirl. Frank Grillo joins the cast as Rick Flag Sr.
