The Marvel Cinematic Universe (MCU) is set to expand dramatically with the release of “Deadpool & Wolverine,” a film that not only promises to fuse humor and heroics but also to potentially reshape the narrative landscape of the MCU. As anticipation reaches a fever pitch, much of the intrigue surrounds what could possibly unfold in the film's post-credits scene—a staple of Marvel movies that often sets the stage for future cosmic confrontations and character introductions.

Also adding to the fervor, Deadpool's creator, Rob Liefeld, has intriguingly hinted that he might know the details of this climactic scene. Liefeld, a pivotal figure in the world of comic books, is best known for his role in creating the merc with a mouth, Deadpool. His contributions to the comic book industry extend beyond this character, having also helped create X-Force and several other notable characters within the Marvel universe. His involvement and endorsement of the post-credits scene speculation have given credibility to the rumors, making fans all the more eager to discover what surprises “Deadpool & Wolverine” might unveil.

Now, Rob Liefeld joins Deadpool & Wolverine's hype with a post on X, where he responds to insider MyTimeToShineHello's comments about Deadpool & Wolverine's post-credits scene, per Screenrant. According to the insider, the post-credits scene “is so mind-blowing” that she “can't believe they were able to pull this off without anyone knowing,” which Liefeld corroborates. Here are ten thrilling theories about what this scene might entail, each suggesting a different but equally exhilarating possibility for how Deadpool and Wolverine's journey in the MCU might continue or dramatically shift.

1. Multiverse Cameos

Presently given the multiversal theme now prevalent in the MCU, one theory posits that characters like Tobey Maguire's Spider-Man or Tom Hardy's Venom could make cameo appearances. The limited rights and complex agreements with Sony and Universal would make such cameos mind-blowing and unexpected, showcasing the expansive reach of the MCU multiverse.

2. Secret MCU Timeline

Secondly, another possibility is a gag that throws Deadpool and Wolverine into a major MCU event, like the Battle of Earth from “Avengers: Endgame.” Such a scenario would not only be a hilarious nod to the characters' comic book histories but also cleverly weave them into the fabric of MCU’s most pivotal moments.

3. DC Universe Crossover

Though highly unlikely due to legal and logistical hurdles, a cameo by a DC character would certainly qualify as mind-blowing. Imagine the shock of seeing a figure resembling Batman or Superman, interpreted in a way that skirts around copyright issues, appearing alongside MCU stalwarts.

4. Shawarma Scene Redux

Echoing the iconic shawarma scene from “The Avengers,” this theory suggests a humorous moment where Deadpool and Wolverine, perhaps alongside other multiverse variants, unwind post-battle in a similar low-key setting. It would be a light-hearted moment reflecting their victory and camaraderie.

5. Retroactive Battle Inclusion

Imagine if the post-credits scene placed Deadpool and Wolverine in the thick of “Avengers: Endgame's” climactic battle via a portal. This integration would be a spectacular way to debut these characters in the MCU, showing them fighting alongside established heroes.

6. Introduction of a New Wolverine

Surely, speculation is rife that the film might introduce a new actor as Wolverine, setting the stage for future MCU narratives. This scene could reveal a new Logan, potentially played by a fan-favorite actor, stepping into the iconic role for upcoming X-Men adaptations in the MCU.

7. Deadpool and Spider-Man Meet

Fans have long wanted to see Deadpool interact with Spider-Man. A post-credits scene could finally bring these two together, especially if it involves Tom Holland's Spider-Man, merging Reynolds' humorous portrayal with Holland's youthful exuberance.

8. Joe’s Pizza Link

A nod to Tobey Maguire's Spider-Man could be made through Joe's Pizza, where Peter Parker worked. This scene could have Deadpool and Wolverine stumbling into this universe, perhaps even running into Maguire’s Spider-Man, in a delightful Easter egg that connects to previous Spider-Man films.

9. A Glimpse into Deadpool’s Time Travels

Following the precedent set in “Deadpool 2,” where Deadpool uses time travel for various antics, the post-credits could depict him meddling in significant MCU events. This would not only be hilarious but also affirm Deadpool's disruptive presence in the MCU.

10. X-Men '97 Crossover

Moreover, with the animated series “X-Men '97” renewing interest in the classic team, the film could bridge animations and live-action by bringing these characters into the MCU. A scene featuring live-action versions of the beloved animated series’ characters meeting Deadpool and Wolverine would thrill fans and open up numerous storytelling possibilities.

Furthermore, each of these theories presents exciting possibilities for integrating “Deadpool and Wolverine” into the MCU and expanding the universe in unexpected ways. Whether any of these theories come to fruition or if Marvel has even more surprising twists up its sleeve remains to be seen, but one thing is certain—the post-credits scene is sure to be a major talking point among fans.
