Fans of the Marvel Cinematic Universe were shaken to the core in July 2021 when Deadpool was featured in an ad with Thor's friend, Korg. As exciting as the moment was, there were now more questions than answers. While it's still unclear what the acquisition means for the character, his comics are full of untouched ideas and team-ups.
The confirmation of mutants was one of the most anticipated elements of the MCU. This year's Doctor Strange in the Multiverse of Madness and Ms. Marvel gave fans what they wanted, but now there are even more questions.
When considering this and the fact that the MCU heavily takes inspiration from X-Men comics, introducing Wolverine seems like a no-brainer. Wolverine and Deadpool are friends, and if The Weapons Plus program or any other team involving the two were to be mentioned, it'd be easy to showcase the pair as a way to directly link the X-Men to the larger universe, just like in Deadpool's comics.
