As excitement builds for James Gunn’s highly anticipated Superman reboot, a major rumor has surfaced online, potentially giving fans a glimpse of what’s waiting after the credits roll. The alleged post-credit scene leaks have sparked a firestorm of speculation—and if they’re true, the future of the DC Universe (DCU) could be far bigger and more interconnected than anyone expected.

Here’s everything we know about the leaked Superman (2025) post-credit scenes, including who might show up, what it could mean for the broader DCU, and why fans should take it all with a massive pinch of salt.

🛑 Warning: Possible Spoilers Ahead 🛑
This information has not been officially confirmed by Warner Bros. or DC Studios. It reportedly stems from a recent test screening, and while some sources like Film Threat are considered reputable, even they note that details are still being finalized. So proceed with caution!

🔍 The Leaked Superman Post-Credit Scenes
According to the leak, two separate post-credit scenes were shown during a recent test screening of Superman (2025). Here’s what supposedly went down:

1. Brainiac Is Teased as the Next Big Villain
The first scene is said to introduce none other than Brainiac, one of Superman’s most iconic and dangerous foes.

“I think introducing Brainiac as a looming threat is really smart,” said one leaker. “You don’t need him in this movie—just tease him. Let him build in the shadows.”
This strategy would follow the Thanos model from Marvel’s early days—set up the big villain early, and give them time to grow in the background before the inevitable showdown. Given that Brainiac is a collector of civilizations, famous for shrinking cities like Kandor, and has deep ties to Kryptonian lore, his involvement could also tie into the presence of Supergirl in the movie.

A Brainiac tease would open the door to epic sci-fi themes, space exploration, and more Kryptonian worldbuilding than we’ve seen in previous Superman films.

2. Green Lantern’s Hal Jordan Appears — Played by Kyle Chandler
The second post-credit scene reportedly introduces Hal Jordan, the most well-known Green Lantern, played by Kyle Chandler (Friday Night Lights, Super 8).

This would not only be a major casting reveal, but also a clear setup for the upcoming Lanterns HBO Max series, which James Gunn has already confirmed is in development and will connect directly to the broader DCU storyline.

“I can completely see this being true,” a source said. “They’re trying to build buzz for the Lanterns show, and introducing Hal Jordan early makes total sense.”
Chandler’s rumored casting suggests a more seasoned Green Lantern, potentially acting as a mentor or veteran figure rather than a rookie. This could offer a grounded, noir-style contrast to the more fantastical elements of Superman’s world.

🤔 But Can These Leaks Be Trusted?
There’s still plenty of skepticism surrounding these rumors. Noted insider Daniel Richtman has stated that none of the Superman test screenings so far have included any post-credit scenes.

So what’s the truth? It’s possible the scenes were added later in post-production or are only being shown to select audiences. Studios often test multiple versions of scenes, especially in superhero franchises.

Additionally, it’s worth noting that previous DC films under the new Gunn/Safran regime haven’t consistently included post-credit scenes—so there’s no clear pattern yet.

🌌 What This Could Mean for the Future of the DCU
If these leaks are true, they suggest James Gunn is laying the groundwork for a massive, interconnected universe right out of the gate. Teasing Brainiac positions him as the next Thanos-level threat, while the Green Lantern reveal adds galactic weight to what’s traditionally been Superman’s Earth-based story.

It’s the kind of world-building that fans have been begging for—but also the kind that requires patience, commitment, and strong storytelling.

🧠 Brainiac: The Ultimate Villain Tease?
Let’s not forget: Brainiac is a fan-favorite villain who has never appeared in a live-action Superman movie. Teasing him now sets a bold tone for the new DCU, one that embraces the deeper sci-fi mythology of the comics.

Imagine a future where Superman, Supergirl, and the Green Lantern Corps are united to stop Brainiac from capturing entire worlds—and possibly rewriting the fate of Krypton itself.

Final Thoughts
At this point, nothing is confirmed. But if these leaks hold any truth, Superman (2025) could end with a bang, not just a hopeful nod to the future. By teasing Brainiac and introducing Hal Jordan, the DCU might finally be positioning itself as a cinematic force to rival Marvel—only this time, with a truly fresh start.

Let’s hope James Gunn delivers.
