Overview

  • The new trailer revealed during Hall H’s DC Studios panel introduces a pocket universe storyline in which Peacemaker confronts alternate-dimension versions of himself and faces a revenge-driven Rick Flag Sr.
  • Footage ties Season 2 directly to the recent Superman film with cameo appearances by Guy Gardner/Green Lantern, Hawkgirl and Maxwell Lord, underlining the series’ role as a narrative bridge in the DCU.
  • Gunn reiterated on the Official Peacemaker podcast that Creature Commandos, Superman and Peacemaker Season 2 are “100% canon” while confirming that certain first-season Aquaman jokes no longer apply.
  • Major legacy heroes Aquaman and The Flash remain excluded from the current DCU slate and are slated for fresh casting, with their eventual integration still under development.
  • Peacemaker Season 2 premieres on HBO Max on August 21, 2025, and will continue offering weekly “what is canon” segments via its companion podcast to guide fans through DCU continuity.
