10 X-Men Mistakes The MCU Must Avoid
5. Take Advantage Of The X-Men's Crossover Potential
Last year, it was revealed that Fox once had plans for an X-Men/Fantastic Four movie that was set to borrow elements from the Civil War comic book series to pit the two teams against each other. For some reason that didn't happen, but Fox never fully took advantage of the X-Men's crossover potential.
At this point, we have faith in Marvel Studios not to disappoint, but there could be a temptation to have the X-Men inhabit their own corner of the MCU rather than fully bringing them into this shared world. After all, what's the point of having The Avengers and X-Men in the same world if they're never going to meet...and fight? However, there are concerns that won't end up being the case.
Last year, there were rumblings that Deadpool will continue to exist in some sort of R-Rated side-universe which has nothing to do with what's happening in the rest of the MCU. That would be a disaster, and while it's going to be hard to suddenly introduce an entire new race to this world, heading down the standalone route would be a complete waste of the potential these characters have.
