Marvel: Unexpected Carnage

So this is the layout of the story since the marvel timeline is very confusing and disoriented I wanna have a basic layout of where everyone is and it's going to change some events but know that every character is the same power wise the only thing that's going to change is where they are in certain time periods. This is happening because I want X-Men and the avengers to merge a bit. However I still wanted to follow the MCU movie series In a way I plan on making changes but they won't be as noticeable until after a certain movie. So just to make it really easy Peter Parker is 18 along with all the X-men that would be in college they will also go to the same school. Also Tony just turned into Iron Man and this takes place at the start of iron man 2. Also the OC is 18.
