Warning: This article contains full spoilers for Peacemaker Season 2’s final episode!

Peacemaker Season 2 just ended its eight-episode run on HBO Max with a major turning point in the life of John Cena’s aspiring do-gooder Christopher Smith. Creator James Gunn teased that the finale would lay the groundwork for 2027’s Man of Tomorrow movie. And Gunn seems to have made good on that promise, with the finale strongly hinting at which character will serve as the common enemy uniting Nicholas Hoult’s Lex Luthor and David Corenswet’s Superman. So why are we so unhappy with the big reveal?

Let’s break down why Peacemaker Season 2’s finale doesn’t quite gel with the rest of the DCU. We’ll also explore the other big revelations in this episode, like the debut of Checkmate and the planet Salvation. Here’s everything you need to know about the ending of Peacemaker Season 2.

Peacemaker Season 2: What’s the Deal With Rick Flag?

Everything seems to be going Chris’ way in the closing moments of “Full Nelson.” He and Jennifer Holland’s Emilia Harcourt finally have their big emotional breakthrough. Chris and the gang liberate a giant pile of cash and use it to open their own peacekeeping agency called Checkmate (more on that in a bit). Chris and Emilia even attend a Foxy Shazam concert, giving Gunn one last excuse to play Season 2’s earworm-y theme song.

But fate has a different plan in store for Christopher Smith. No sooner does he win it all than it’s cruelly taken away from him by Flag and his ARGUS agents. “Full Nelson” ends with Chris being abducted and taken to an ARGUS black site facility. There, he’s promptly dumped into a world Flag has selected for his metahuman prison planet. Gunn confirmed at a press conference that it’s called Salvation (again, we’ll get to that in a little while). Flag banishes Chris in revenge for the death of his son, Joel Kinnaman’s Rick “Ricky” Flag, Jr, leaving Peacemaker marooned and weaponless in a land full of hungry monsters. And it sure sounds like he’s just the first of many planned prisoners.

Before getting into the comic book origins of Checkmate and Salvation, we really need to address the elephant in the room. What’s the deal with Rick Flag? Why has this character taken such a hard and sudden heel turn in Peacemaker Season 2?

The thing about Grillo’s character is that he was never portrayed in a particularly villainous light before now. From the start, he’s been the more level-headed, rule-abiding alternative to Viola Davis’ Amanda Waller. If outright calling him a hero is too much, Flag was certainly on the right side of the conflict in 2024’s Creature Commandos. The same goes for his small role in Superman, where he was clearly distrustful of Luthor.

Even starting out in Peacemaker Season 2, Flag wasn’t really a villain so much as a man grieving the death of his son. However much Flag may be using his position to carry out a personal vendetta, you can understand and empathize with him. But that empathy is mostly gone now. Flag has gone from distrusting Luthor to becoming Luthor. Is there any difference between Luthor building a prison between dimensions and Flag using the QUC to dump prisoners on an alien world?

Even the way Flag treats his agents in Episode 8 seems like a step too far for the character. We see him sending wave after wave of ARGUS troops into the QUC as glorified cannon fodder, joking and flirting while his men die horrible deaths. Again, calling Flag an outright hero may be too much of a stretch, but the character had a basic humanity in the DCU that’s suddenly absent at the end of Peacemaker Season 2.

Is Rick Flag the Villain of Man of Tomorrow?

This sudden pivot in Flag’s characterization is all the more troubling because all signs point to the character taking on a bigger role in Gunn’s Superman follow-up, Man of Tomorrow. For all the speculation that Brainiac is the major threat looming over the heads of Luthor and Superman, it’s looking like Rick Flag Sr. is the actual villain of Gunn’s next movie.

Flag clearly has a distaste for metahumans (despite previously leading a team of them). He sees them as causing more problems than they solve, nothing more than trash to be disposed of on a remote, out-of-the-way planet. In Man of Tomorrow, Flag may decide that Luthor should be among that group. That may be what forces Luthor to align with his most hated enemy. Superman is never one to turn down someone in need. Plus, he knows firsthand how dehumanizing it is to be abducted and imprisoned with no due process.

Flag may be the threat that forces Superman and Luthor to put aside their differences and fight for a common goal. We may even see both characters banished to Salvation in Man of Tomorrow, cueing up the inevitable return appearance of Cena’s Peacemaker. It seems that absolute power is corrupting Flag in the same way it did Waller before him.

Again, it’s just a little hard to swallow this abrupt pivot in characterization with Grillo’s character. Part of the appeal of Flag was that he wasn’t Amanda Waller. Why even sideline Waller in the first place if we’re just getting another person with the same temperament running ARGUS? Hopefully, Gunn has something else in mind for Flag that can restore him to a more morally ambiguous player in the DCU rather than an outright villain.

That said, Gunn would argue that Flag was never the noble character he might have seemed in Creature Commandos and Superman. At a recent press event, Gunn noted that Flag is a deeply flawed character whose greatest sin is overestimating his own intelligence.

“I think we saw a guy in Creature Commandos, which, when you’re first watching that season, he seems like he’s the good guy, but he’s absolutely not,” Gunn told reporters. “He screws up everything again because he thinks he’s smarter than Waller, which he isn’t. And he messes that up and he falls for this woman and is kind of played by her… the whole time. And that to me is the fun thing about Rick Flag. He’s totally imperfect.”
