The first trailer for Justice League's finale cameo, Peacemaker season 1 largely stands on its own.

With DC's projects existing in the new DCU, Peacemaker's talented cast make the jump to the DCEU. The multiverse always seemed like the easiest explanation to show how the characters now exist in the DCU, but since the franchise is just starting, I did not expect the multiverse to be used so soon. However, my new Peacemaker season 2 theory after the trailer was released explains how the door is open for the perfect multiverse story.

The Peacemaker Season 2 Trailer Teased A Multiversal Story

The New DC Universe Has To Explain How The Show Survives A Universe Change

While we knew Peacemaker season 2 would feature Frank Grillo's Rick Flag Sr., connecting the show to the DCU's first two releases, Creature Commandos and Superman, there were quite a few surprises in the first Peacemaker season 2 trailer. Peacemaker season 2 continues the overall storyline of the first season, with John Cena's Christopher Smith having saved the world from the butterflies. That leads him to try to Maxwell Lord's Justice Gang, and I was surprised by how deeply rooted in the DCU season 2 is.

Nathan Fillion's Green Lantern Guy Gardner and Isabela Merced's Hawkgirl both appear in Peacemaker season 2. However, despite that clear connection to the DCU, the trailer's ending is the most interesting part of the footage for Cena's DCU story. We see two versions of Peacemaker share the screen, with one in full superhero suit pointing a gun at an underwear-wearing Christopher Smith. I'm convinced those will be the DCU and DCEU versions of Peacemaker, respectively.

The DCU Series Has An Important Job To Pull Off

Given how the events of The Suicide Squad, which is a DCEU movie, are crucial to Peacemaker's story, there was a lot of talk about how the show could be moved to the new DC Universe and still retain its key elements. Well, given how the animated Creature Commandos seamlessly weaved the death of Rick Flag Sr.'s son into the plot, I have no doubt Peacemaker season 2 will do a great job of merging both franchises. It also helps that James Gunn has a plan for that.

The brand-new trailer for Peacemaker season 2 makes a few of my post-Superman DCU theories way more likely (especially with the Justice Gang).

In January 2024, Gunn took to Threads to answer a fan's worries about how Peacemaker season 2 being set in a different universe could be confusing for those who watched season 1. According to the DC Studios creative chief, there is no reason to worry. Gunn revealed he has "a way in" that will guarantee the story makes sense. While Gunn did not mention the multiverse as the plot device he would use, I have a dark theory for Peacemaker season 2 after watching the trailer, and it would explain the universe change with a twist.

Peacemaker Season 2 Theory: John Cena’s DC Hero Kills Himself

A Key Location From Season 1 Returns With A Crucial Role

John Cena as two versions of Christopher Smith in Peacemaker season 2

The Peacemaker season 2 trailer shows two versions of John Cena's Christopher Smith confused as they meet for the first time. I believe the multiverse is in play here rather than time travel, as the version of Peacemaker who has a gun sports a new helmet and, most importantly, the dove emblem on his chest is facing upwards. In Peacemaker season 1, Smith's suit emblem was inverted, with the dove looking down. I'm convinced that is a subtle tease about the different universes.

In Peacemaker season 1, we learned that Smith's father had built a pocket dimension closet. In the Peacemaker season 2 trailer, Cena's DC character goes through a door there and seemingly arrives in a new universe, coming to meet another version of himself. My Peacemaker season 2 theory is that the DCEU version of Chris has arrived in the DCU in the scene we see in the trailer, and he will kill his DCU self to take his place. That allows all his DCEU backstory to continue while setting Cena up for DCU adventures in Peacemaker season 2 and beyond.
