9) The X-Men
If you’ve read Old Man Logan, you’ll know that it’s revealed in flashbacks that Wolverine gave up his life as a superhero after he was tricked into slaughtering his fellow X-Men. When a group of supervillains decided to take over America, they targeted the X-Mansion and Logan went on the attack. After slicing his way through them all, it was revealed by Spider-Man villain Mysterio that the whole thing was an illusion and that Wolverine had just killed his friends.
Distraught, he attempted suicide, and it’s easy to imagine a scene similar to this playing out in this movie. If that’s the case, some familiar faces from the original timeline showing up as they did at the end of Days of Future Past is very likely, but will Fox have the guts to show Wolverine killing the X-Men, even in an R-Rated flick?
