What if the Avengers, Spider-Man, Fantastic Four, and X-Men came together? (Fan) Trailer

Suggested by Eclipsewolf583. What if The Avengers, Spider-Man, the Fantastic Four, and X-Men all worked together to create Ultron. What if Ultron betrayed them and made his own team with Magneto, Dr. Doom, Green Goblin, and the Maximoff twins (who were on their fathers side, Magneto, but then joined The Avengers side). What if The Avengers, Spider-Man, Fantastic Four, and X-Men joined forces to defeat Ultron and his team/army. Im only doing a suggestion like this once because a lot of people wanted this suggestion so I will continue to follow the rules of What If? Do you want to see a particular superhero in any movie? If so, leave your idea in the comments below and Ill take each into consideration. If theres a certain idea that is very popular then Ill definitely choose that one since a lot of people want it to happen. Make sure to check the post title scene for next weeks What If(s)? Last times What If? was What If Iron Man was in Pacific Rim? so be sure to check it out if you havent already. I do NOT own anything and this is for entertainment purposes NOT profit.
