Coming in hot from San Diego Comic-Con 2025 is a new trailer for Peacemaker Season 2, which finally reveals how John Cena’s Chris Smith jumps from his DCEU dimension to an alternate DCU dimension.
DCU steward James Gunn is bringing most of Peacemaker Season 1, which was a part of the DCEU, into the DCU canon with Season 2, which takes place one month after the events of Superman.
Making peace with yourself is harder than it looks.

Peacemaker discovers a new universe via a Quantum Unfolding Chamber (QUC), with Frank Grillo’s Rick Flag Sr. out for revenge for the death of his son. We see Peacemaker go through to the other side, which he instantly finds more appealing (the grass is always greener etc.). However, as teased in the video, Peacemaker ends up meeting alternate dimension Peacemaker and of course the two end up in a fight.
However, there are 100 alternate dimensions of the DCU, and we see one of those in the trailer with a war-torn battlefield packed with what look like giant spider creatures with skulls for heads.
Peacemaker returns for its eight-episode second season on Thursday, August 21 at 9pm ET on HBO Max. James Gunn wrote all eight episodes of Peacemaker and directed three, including the first episode, which features Guy Gardner and Hawkgirl from Superman.
During a panel at Comic-Con, Gunn confirmed other characters from Superman (besides Rick Flag Sr., Hawkgirl, Guy Gardner, and Maxwell Lord) will return in Peacemaker Season 2. Michael Rooker (who starred in Gunn’s Guardians of the Galaxy films for Marvel), plays a character named Red St. Wild, who acts as “Eagley’s Lex Luthor,” according to Gunn.
Here’s the official blurb:
In season two, Peacemaker discovers an alternate world where life is everything he wishes it could be. But this discovery also forces him to face his traumatic past and take the future into his own hands.
