AVENGERS: DOOMSDAY Rumor May Reveal Details of the Movie’s Massive Final Battle

Marvel fans have been swimming in supposed plot leaks for Avengers: Doomsday for months now, but how does this thing actually end? Not the emotional fallout or the post-credits chaos, but the final throwdown that sends us hurtling toward Secret Wars.

Well, a new rumor might finally give us a clearer picture, and if it’s even half true, the finale sounds wild. The latest chatter comes from scooper MTTSH, who claims the climax of Doomsday brings together just about every heavy hitter Marvel has on the board.

According to the rumor, the final battle sees the Avengers teaming up with the Fantastic Four and the X-Men to take on the Latverian Armada. Earth’s Mightiest Heroes, Marvel’s First Family, and the mutants all sharing the battlefield against Doctor Doom’s full military force.

If this pans out, it would be a major shift from an earlier report that suggested the X-Men wouldn’t factor into the final act at all. This new version seems more in line with the scale Marvel’s been building toward, especially with Victor Von Doom positioned as a Multiversal-level threat.

A technologically advanced Latverian army backing Doom in a massive crossover showdown feels like the kind of escalation Doomsday needs.

There’s been other reports floating around too. One previous rumor claimed Doom would assemble his own twisted squad of Dark Avengers, but what seems more plausible is Doom entering the final fight with unexpected allies.

We’ve heard that several characters could be manipulated into siding with him under the belief that he’s trying to save the Multiverse. Peggy Carter has been mentioned specifically, which opens the door for some morally messy confrontations once the truth comes out.

How all of this connects to Avengers: Secret Wars is still anyone’s guess. There have been reports about Battleworld and fractured realities, but Marvel is keeping those cards close to the chest.

If this rumored ending is legit, Doomsday could wrap with the heroes barely surviving a full-scale war against Doom’s forces, setting the stage for reality itself to finally snap.

One thing we do know for sure is when we’ll get answers. After some major scheduling shifts last year, Avengers: Doomsday is now locked in for a December 18, 2026 release, with Avengers: Secret Wars following on December 17, 2027.
