Peacemaker is already tangled up with James Gunn's new DC universe, and it sounds like Season 2 is about to pull one more thread from his Superman movie. Gunn just teased another crossover and a finale surprise that, frankly, sounds like he's daring the internet to guess wrong.
Quick refresher: Peacemaker Season 2 is the John Cena-led follow-up from Gunn, who is also the co-CEO of DC Studios and the guy steering the upcoming Superman film. So when he teases cameos, it matters for the bigger DCU picture.
"You will see one more character from Superman."
"There is also one really big appearance by somebody in the end of the season that I don't think people will see coming."
That first part is pretty straightforward: someone who appears in Gunn's Superman will show up in the back half of Peacemaker Season 2. He would not say who. The second part is trickier. He also promised a major appearance in the season's closing stretch, but he would not clarify if that surprise is from the Superman cast or just a different DCU face entirely.
The fan theory with the most heat right now is Nicholas Hoult as Lex Luthor. Why? This season leans hard into multiversal travel, and some of the baddies' armor (the 'Top Trio' crew) looks suspiciously like the kind of kit you would expect from Luthor's forces. That visual echo has people connecting the dots. Other names getting tossed around: Lois Lane, Jimmy Olsen, and, sure, Superman himself.
Worth noting: Season 2 has already brought in a stack of DC players tied to the Superman movie. We have seen Hawk Girl, Guy Gardner, Maxwell Lord, and Rick Flag Sr. pop up, and the show did not just toss them in for a quick wink—they actually matter in the season.
- Confirmed by Gunn: one more character from his Superman film will appear in upcoming episodes
- Also teased: a big, end-of-season appearance that may or may not be tied to the Superman movie
- Popular guesses: Nicholas Hoult's Lex Luthor, Lois Lane, Jimmy Olsen, or Superman
- Season 2 so far: Hawk Girl, Guy Gardner, Maxwell Lord, and Rick Flag Sr. have already shown up
- Context: this season features a lot of multiverse hopping, and some villain armor looks very Luthor-adjacent
- Timing: there are three episodes left for the cameos to hit
Bottom line: Gunn is clearly stitching Peacemaker and Superman together. With three episodes left, expect at least one more straight-from-Superman drop-in and one finale shocker. If you are placing bets, Lex makes a lot of sense—but Gunn lives to zag.
