Avengers: Endgame - Mysteries Answered

5. Will Any Of The Fox Superheroes Cameo?

The Disney-Fox merger inevitably raised plenty of questions surrounding the MCU's future, with Marvel now being able to use iconic comic-book characters like the X-Men and the Fantastic Four.

One rumour which just would not go away surrounded Wolverine potentially showing up during Endgame, either in a post-credit sequence or during the team's adventures through time and space.

Now that the film's out though, we know that there isn't even a solitary hint towards any of these wider characters being introduced. That's probably for the best though; this was all about sending up the past 10 years of the MCU, and it wouldn't have felt right to then tack on fan favourites from another studio so steal their thunder.
