Everything we know has already been changed after the events of Avengers: Infinity War, but another thing we know is that the Marvel Cinematic Universe won't stop there.
While Phase 1 saw the introduction of heroes, Phase 2 brought about new concepts to the universe such as the Infinity Stones, and Phase 3 built up to the war for existence.
Now, Phase 4 will see a different universe and we're all for it! Here's how Captain Marvel will change it all.
5. Introducing the Kree And a New Alien Hero
The Kree race were introduced in Guardians of the Galaxy, but it turned them into the bad guys as Ronan was the only Kree we were introduced to. However, there was a hero that Carol adopted her name and powers from and that's Captain Mar-vell, who'll be played by Jude Law in the upcoming film.
Introducing a new race of aliens opens up the MCU to expanding their universe to include other races that affect the Marvel Comics Universe and brings about some of the biggest arcs in Marvel Comics history!
4. Introducing the Skrulls and a New War
Okay, this is a big one!
When it was confirmed Captain Marvel would be dealing with the Kree-Skrull War, it meant the world would be open to introducing the shapeshifting alien race of the Skrulls to Earth.
That can only mean Marvel could be planning the next big ensemble event which could take place further down the line involving a lot of shapeshifting, broken trusts, and... well, another war.
3. Nick Fury's Past And S.H.I.E.L.D.
S.H.I.E.L.D. fell after getting infiltrated by Hydra during its conception as revealed several movies earlier in the timeline. (Spoiler, I guess, but it's been years, and if you missed Captain America: Winter Soldier, then why are you reading instead of catching up on of the greatest Marvel movies?)
However, in Captain Marvel, we'll be seeing a younger Nick Fury as well as what S.H.I.E.L.D was like years and years ago before the idea of the Avengers was even born in the MCU.
2. New Planets and Other Worlds
Alright, I can't stress the importance of expanding the MCU beyond the worlds and locations that we've visited so far in all the movies up until Infinity War.
If the MCU has any hope of including some major epic arcs that readers have seen, then we need to include and see more worlds out there whose races and people will eventually make their way to influence the events on Earth.
1. She Could Link the MCU with the X-Men
Carol Danvers hasn't always had the best of luck with the Avengers (in the comics) seeing as how she's a fiery, stubborn hero, with galactic powers (not cosmic or world-breaking, just present elsewhere in the galaxy) and doesn't always play by the rules.
However, a team that she frequently interacts with are the X-Men. Now that Disney is in the process of gaining control of the rest of the Marvel world, Carol Danvers could be that missing link that could seamlessly blend in the X-Men presence with that of the MCU.
Needless to say, with the summoning of Captain Marvel at the end of Infinity War, we know that Carol Danvers will play an important role in "the endgame".
We'll have to wait for more trailers, more sneak peeks, and more set photos if we're going to unravel the little mystery that is the upcoming Captain Marvel film.
