Before I Begin, I would like to say that my previous theories, All though outlandish, Have for the most part come true, I encourage you to read not only my other articles but also the comments, because people doubted my thoughts.
That being said, there was a recent rumor going around that Fox and Marvel are looking to make a movie with the Avengers and the Xmen coming out by 2020. Now honestly I doubt this but I started thinking, " What if? What if they did this? Would they have to reboot both the New Xmen universe (Post DOFP) and the new Fantastic Four?" Then it hit me! What would be the perfect way to include both of these into the MCU. Or should I say who? I have two words for you my friend
Invisible Woman
Aka
U.S. Marshall Woman
Yep I'm going there. With Kate Mara appearing in Iron man 2 and the fantast four, it opens up something elses entirely. What if the Fantastic Four is already in the same universe as the Avengers, what if U.S. Marshall woman real name is Sue Storm. I know that this is getting a little stupid but bare with me. With the basis of the Fantastic Four being inter-dimensional travel, it gives the opportunity to use not only the Current Xmen universe but also opens up a world ( or worlds) of possibilities. We know a marketing strategy of Marvel is to use their comic books as a build up to their movies. So heres what I think they could use as their outline for Phase 4
In case you've been living under a rock, there is no more multiverse in the Marvel Comic Universe, All of them have been smashed into one. Now how does this apply to the Cinematic Universe. It all goes back to Fantastic Four. They would open a interdimensional portal that would, for a lack of a better word, "Explode" and cause all of these universes to come into one. Fantastic Four, the Xmen, Avengers would all come into one universe (and for a mini rant we could do a spider-verse movie for all those Andrew Garfield and Tobey Maguire lovers, Possibly even bring emma stone back for Spider-Gwen) Secret Wars could be the New avengers title or it could be the status quo for the entirity of Phase 4. We could have each movie have all the different versions of our heroes. In Short, the Fantastic Four/Secret Wars is the key to having our favorite characters on screen together and not have to deal with the agonization of reboots. Thank you for reading and feel free to bash on or to share how this can be made better.
