Why a Single Line in the Deadpool & Wolverine Trailer Has Fans Rethinking the Entire MCU Timeline

Why a Single Line in the Deadpool & Wolverine Trailer Has Fans Rethinking the Entire MCU Timeline

Marvel Studios recently dropped the much-anticipated trailer for Deadpool & Wolverine, and as expected, it sent ripples across the Marvel fandom. While there’s a lot to unpack—Wolverine’s reluctant return, Deadpool’s signature meta humor, and mind-bending multiverse teases—there's one line that truly stands out. A seemingly simple piece of dialogue has sparked major speculation, theories, and debate, prompting fans to reconsider what they thought they knew about the MCU timeline.

If you’re tuned into Marvel's vast universe, this line could rewrite everything. Let’s examine what makes it so profound and why fans believe it might change the direction of the Marvel Cinematic Universe.

   

The Line That Changed Everything

About midway through the trailer, Deadpool turns to Wolverine and drops the astonishing line: "We're not just saving this world... we're saving all of them."

At first glance, it sounds like typical Deadpool hyperbole. But to longtime fans who understand how intricately woven the MCU's multiversal dynamics have become since Avengers: Endgame and Loki, the implications are massive. This one sentence suggests that Deadpool and Wolverine’s journey isn’t limited to one universe or timeline. Instead, they might be embarking on a mission that connects multiple universes—possibly all known realities under the Marvel banner.

   

MCU Timeline Mayhem: What’s Changed?

Since Phase Four, the concept of a coherent timeline in the MCU has grown increasingly blurred. With the introduction of the multiverse in shows like Loki and movies such as Doctor Strange in the Multiverse of Madness and Spider-Man: No Way Home, the rules that once grounded the universe have dissolved into chaos.

Deadpool’s comment about “saving all of them” reinforces the notion that what we see in the MCU is no longer limited to one linear progression of time. Instead, it suggests a deeply interconnected multiverse where events in one timeline ripple into others. This can open up endless possibilities, but it also means major reorganizing of how fans interpret the sacred timeline initially laid out by the Time Variance Authority (TVA).

   

The X-Men Integration Gets Even Wilder

Deadpool and Wolverine are both Fox Universe characters, which originally existed outside of the MCU canon. But thanks to Disney’s acquisition of 21st Century Fox, their cinematic universes are now fully accessible to Marvel Studios. That line in the trailer may very well confirm the moment we’ve all been waiting for—the official bridge between the Fox X-Men universe and the MCU multiverse.

If “saving all worlds” includes alternate timelines like the ones we saw in Days of Future Past or Logan, then the door is wide open for cameos, retcons, or even revised history. Wolverine’s presence alone makes this idea plausible, especially since the character supposedly died in Logan—a film set in the future of the Fox timeline. This means we could be exploring another variant of Wolverine, not the same one from past X-Men films, but one that’s still desperately important to the timeline's balance.

   

Connection to Avengers: Secret Wars and Kang Dynasty

Speculation is mounting that Deadpool & Wolverine could be a major precursor to the highly anticipated Avengers: Secret Wars. That storyline, known for its dramatic multiverse collisions in the comics, is centered around the disintegration and rebirth of universes. Deadpool hinting at a multiversal rescue mission feeds into the idea that his and Wolverine’s actions could directly influence the lead-up to these crossover films.

Furthermore, this line could mark the beginning of Marvel’s exploration of the Incursions—a catastrophic event where two realities collapse into each other. This was briefly teased in Doctor Strange 2. Could this be the start of the collapse that Secret Wars aims to resolve? It’s not far-fetched, considering how connected everything has been thus far.

   

This Changes Canon As We Know It

Deadpool has always been the wild card, often breaking the fourth wall and poking fun at MCU tropes. But now, it seems that Marvel is using his unique perspective to usher in massive multiversal changes that will affect canon, continuity, and viewer expectations. “Saving all the worlds” isn’t just a throwaway line—it’s a mission statement for the next phase of the MCU.

This could allow Marvel to reset or recontextualize underperforming narratives, explain continuity errors, and even bring back fan-favorite characters in entirely new ways. Think of it as a soft reboot masked as a multiversal epic. It’s clever, bold, and on-brand for Deadpool’s chaotic energy.

   

Final Thoughts: A New Era for the Marvel Cinematic Universe

One trailer. One line. One giant leap for multiversal storytelling. Deadpool’s now-famous line in the Deadpool & Wolverine trailer has become a lightning rod for fan theories, speculation, and excitement—and it’s easy to see why. It encapsulates the vast, unpredictable terrain that Marvel is now choosing to navigate in the Multiverse Saga.

If this film truly bridges the gap between the Fox X-Men universe and the prime MCU timeline, it won’t just be a turning point for Deadpool and Wolverine—it’ll be a pivotal chapter for the entire Marvel franchise. Don’t blink, Marvel fans. The timeline is changing, and it all starts with this one insane, universe-saving adventure.
