MCU: 8 Billion Dollar Marvel Movies To Justify Buying Fox

4. Avengers: The Galactus Saga

For a lot of people, the biggest problem with the MCU is that there simply aren't enough great villains to go around. There might have been big successes with Loki, Vulture and Black Panther's Erik Killmonger, but there have also been way too many mediocrities and misfires for a franchise this big.

In that respect, it's great news for Marvel that they've now secured the rights to Galactus - who legitimately qualifies as one of the top three greatest ever Marvel villains - and it means they've got a ready-made replacement for Thanos when his Infinity Saga is done with.

However they decide to do it (specifically, the logistics of bringing the Fantastic Four in would be a point of concern - or at least a big creative opportunity), Galactus will be coming to the MCU, and the best way to frame him is as the villain in an Avengers movie. And that would be a recipe for huge success.
