Avengers: Endgame may herald the end of the MCU's third phase, but it's also important to remember that it will usher in the start of a new one too.

Beginning with Spider-Man: Far From Home, Disney's premier superhero franchise will embark on a "distinctly different" era of comic book adaptations, with The Elementals, Shang-Chi and several other characters set to arrive just at the same time old staples like Iron Man and Captain America depart.

It's a period of immense change for Marvel, and with Endgame likely to conclude Thanos' arc for good (built up for a good 20 films, lest we forget), Marvel's heroes will find themselves with new threats to take on, new allies to recruit and even new franchises to absorb, with Disney's takeover of Fox opening the door for the likes of the Fantastic Four and X-Men - plus all their associated characters - to join the series too.

It's exciting and daunting in equal measure, but if you thought that the sheer array of rumours for Avengers: Endgame was bonkers, then you should take a look at what the internet's discussing in the build up to Phase 4. Theories regarding recurring bad guys, surprise cameos and brand-new additions abound everywhere, and though some are more legitimate than others, all are worth discussing in one way or another.
