How Marvel Should Bring The X-Men Into The MCU
5. Avengers Vs. X-Men
When you think of the X-Men joining the MCU, there's one eventuality just about every comic book fan will immediately consider and salivate at the thought of: the Avengers vs. the X-Men.
If the X-Men do arrive through some sort of dimension-tearing event, then it wouldn't be at all surprising that the Avengers would be wary of them, especially after just battling Thanos.
Though the writing would need some real nuance to it to stop the conflict from feeling overly contrived, the blockbuster appeal of Wolverine squaring off against Iron Man or Captain America (assuming they're still around by 2021 or so) really speaks for itself.
If you thought Civil War was something, this has the potential to be even bigger, as long as Marvel Studios doesn't rush the X-Men's introduction in the pursuit of another $1.5 billion payday.
