DCU boss James Gunn has hinted at a major cameo appearing toward the end of Peacemaker Season 2, though he remains tight-lipped about whether the character will also appear in the upcoming Superman film or is tied to another corner of the newly rebooted DC Universe.
The Superman movie, set to release this summer, takes place before Peacemaker Season 2, which premieres on HBO Max (yes, they’ve changed the name back) on August 21, 2025. Supergirl follows on June 26, 2026, while the release date for the Lanterns TV series remains unannounced. Both projects are set in-universe after Superman and Peacemaker Season 2.
Earlier this month, Max dropped a new trailer for Peacemaker Season 2, revealing that Superman-adjacent characters Maxwell Lord, Hawkgirl, and Guy Gardner are seen interviewing Peacemaker for a spot in their team. Spoiler: it doesn’t go well.
In an interview with *Entertainment Weekly*, Gunn emphasized the deep narrative ties between *Peacemaker* Season 2 and the broader DCU, especially *Superman*. “It’s very much connected to Superman and it's very much connected to what comes after,” he said, teasing even more layered crossovers.“The QUC, or Quantum Unfolding Chamber, which debuted in Peacemaker Season 1, plays a bigger role in Superman,” Gunn explained. “In Season 2, the QUC is central to the story. We’ll see characters from Superman like Isabela, Nathan, and Sean, plus a number of other figures later in the season from across the DCU. There might even be one really, really, really big cameo near the end.”
Gunn confirmed that Peacemaker Season 2 takes place a few years after the Season 1 finale, though the exact timeline remains intentionally flexible. “I know from my time at Marvel how hard it is to make everything fit perfectly,” he said. “So it’s an unspecified couple of years—enough to feel like time has passed, but not so rigid that it causes continuity strain.”

As has become apparent in recent months, several characters are set to appear across Superman, Peacemaker Season 2, Supergirl, and Lanterns. With so much overlap, fans are asking: will the DCU introduce a chronological timeline like the MCU’s Disney+ watch order?
Gunn addressed this recently on social media, clarifying that for now, the DCU timeline aligns with release order—though flashbacks will play a role. “As of now, it's basically as the movies and shows come out — although of course some of these feature flashbacks — Creature Commandos, Superman, Peacemaker, Lanterns, Supergirl,” he explained.
While Disney+ offers a curated chronological timeline for the MCU, HBO Max currently has no plans to replicate that feature. However, as the DCU expands, such a tool may eventually become necessary.

Gunn noted that Waller, the *Peacemaker* spinoff, “has had a couple of setbacks, frankly.” On a brighter note, the HBO Max series Booster Gold “is going pretty strong,” and Paradise Lost remains “totally, still important and we're working heavily on it.”With so many shared characters across projects, fans are curious about how the Superman movie will handle its growing roster of side characters. The latest trailer introduced viewers to Mister Terrific, The Engineer, newcomer The Hammer of Boravia, and the enigmatic Ultraman—hinting at a rich, interconnected universe unfolding on screen.
