Buckle up, because the first big Avengers: Doomsday post-credits rumour has landed, and it is exactly the kind of insane that Marvel fans live for. According to chatter making the rounds this week, Doomsday will end not with one tag but two, and both are reportedly built to launch us straight into Secret Wars.
The claim comes from insider James Mack, who posted the breakdown on X. Nothing here is confirmed by Marvel or Disney, so treat it like the spicy rumour it is. But if even half of it is real, the Avengers Doomsday post-credits scenes are going to break the internet on December 18.
What the Avengers Doomsday post-credits scenes rumour claims
Per Mack, there are two Avengers Doomsday post-credits scenes. The first is a Loki scene. The rumour says Loki actually dies during the movie itself, which is already a gut-punch, and then turns up alive in the first tag, except he has lost his powers. A depowered God of Mischief stumbling into Secret Wars? That is a story engine if we have ever heard one.
The second scene is the one that had everyone screaming. It reportedly shows Tobey Maguire’s Spider-Man standing alongside Hugh Jackman’s Wolverine on Battleworld, the patchwork planet Doctor Doom cobbles together in the comics version of Secret Wars. In other words, the tag is a direct bridge to the next Avengers film.
The Russo Brothers reportedly want these scenes to be extremely serious, with no jokes whatsoever.

That last detail is the tell. A tonal swing toward dead-serious, stakes-first stingers lines up with everything the Russos have been saying about Doomsday being a darker, heavier chapter than the quippy Marvel of old.
Loki dies again? Fans already have opinions
Here is where the fandom split in about four seconds. Loki dying and resurrecting is basically a franchise running joke at this point, and plenty of fans are tired of the character getting killed just to be walked back. Losing his powers, though, is a genuinely fresh wrinkle.
Remember, Loki ended his own series holding the entire multiverse together at the He Who Remains throne. If Doomsday strips that away and drops a mortal Loki into the run-up to Secret Wars, it recontextualises a lot. For the full picture on how these two films hand off, we broke down how Doomsday and Secret Wars connect.
Tobey Maguire and Hugh Jackman on Battleworld, explained
The Tobey-and-Jackman tag is the headline for a reason. Battleworld is the beating heart of Secret Wars, a stitched-together planet made of fragments of dead universes. Seeing two of the multiverse’s most beloved variants standing on it would basically confirm that the Sacred Timeline is done and the incursions have won.
It also fits the mountain of casting chatter we have tracked. If you want the receipts, here is every confirmed Doomsday hero and villain and the full pile of Doomsday plot leaks so far. This new stinger rumour slots neatly beside them.
How much should you actually believe this?
Honestly? Keep the excitement on a low simmer. Single-insider post-credits claims for a movie four months out are the most leak-prone, most changeable thing in all of Marvel reporting. Tags get rewritten in reshoots, cameos fall through, and Battleworld reveals are exactly the kind of secret Marvel guards hardest.
That said, the concept passes the sniff test. Two tags, a Secret Wars springboard, and a Battleworld money shot is precisely what you would expect from the end of Doomsday. We have logged this one on our scored Marvel rumour tracker so you can watch it rise or fall as more sources weigh in.
What happens next
Doomsday hits theatres on December 18, which means we are entering the season where every edit-bay whisper leaks. Expect more scoopers to either back this up or shoot it down within days, and expect Marvel to say absolutely nothing either way.
So, over to you: is a depowered Loki plus a Battleworld tag the ending you want, or are you done watching Loki die and come back? Tell us in the comments.
