This ending of the series the second season leaves a massive cliffhanger that could have major ramifications for the future of the DCU. Although it's currently unknown if the series will get a third season, the showrunner has stated that the events will directly lead into the upcoming Superman film. Considering this, one specific detail from the Peacemaker last episode might hold the key to understanding the mysterious villain of the Man of Tomorrow movie.

Intrigued? Let's dive in.

Full reveals ahead for the end of Peacemaker season 2.

Peacemaker Second Season Ending Explained

In the finale of Peacemaker season 2, ARGUS, led by its leader, explores the multiversal doorway that Peacemaker handed over in the prior installment. At first it's unknown what they're seeking, until they find it: a habitable planet where Flag can exile all of Earth's superpowered beings. He names this planet the new prison, with intentions to use it as a giant, secure jail.

In the final moments of the installment, the team captures Peacemaker and shoves him through the doorway into the planet. Flag explains that Chris will be his test subject to make sure the planet is actually habitable and the portal disappears behind him, stranding the hero all alone on an alien planet in a different reality. After that, we hear a cacophony of roars that seem like a bunch of unseen creatures about to devour him. The episode ends.

What exactly does it signify? To grasp it, it's worth examining the lore of DC Comics, specifically, the story of the comic series.

Salvation Run and the Series

Published in the late 2000s during the Final Crisis, Salvation Run was a limited series based on an idea from the author. It was written by the writer and his co-writer, with illustrations by Sean Chen, Walden Wong, another artist, and Belardino Brabo.

The core idea of the comic was that the task force (under its commander) apprehended a group of villains and exiled them to a remote world called the prison planet. The list of captive antagonists included the genius, the clown prince, the mutant, Bane, Deadshot, the ape, Hugo Strange, the shapeshifter, Mister Freeze, the botanist, the wildcard, and dozens more. Waller also added some morally ambiguous characters, like Catwoman, for good measure.

The idea was to let the villains fight it out and perish, but there was a surprise. It was revealed that Salvation was actually a "proving ground" for the deities of Apokolips, aka, the nightmarish planet ruled by the tyrant. To make matters worse, Salvation was under the control of one of the ruler's most terrifying followers: the torturer.

DeSaad and the Man of Tomorrow

According to DC lore, he has a distinct purpose: he's Darkseid torture guy. DeSaad is also a brilliant who enjoys creating new ways to inflict suffering on his victims, and is pretty much ageless. In some versions, he's incredibly powerful, too, and has abilities like mind-reading and the ability to control others' emotions. In other words, he's terrifying.

Assuming the showrunner is riffing on the Salvation Run story (which appears probable based on the prison planet's name in Peacemaker), then it seems logical that he could be introducing DeSaad as the DCU's next primary antagonist. This would definitely be a daunting enough menace to get Superman and the genius working together on the same side against a common enemy — particularly if Lex regrets for coming up with the notion of a multiversal prison in the first place.

Admittedly, we're making educated guesses here, but based on the conclusion of Peacemaker the second season, the torturer just jumped way up in the list for Man of Tomorrow's primary antagonist. And as an added bonus, he could act as an prelude for the ruler himself once the director gets around to making his own team-up movie.

Thankfully, we won't have to wait too much longer to learn for sure. The Superman movie is expected to start filming in the spring of 2026.
