Avengers 5: 10 Possible Storylines It Would Be Awesome To See In The MCU
1. Kree/Skrull War
The Kree/Skrull War played out in Captain Marvel, and regardless of when the movie's upcoming sequel takes place (it's likely the present seeing as Ms. Marvel is rumoured to appear), then there's a very good chance the battle between these alien races has already concluded.
However, just because Carol Danvers managed to put an end to it thirty years ago, that doesn't mean the old conflict can't resume, albeit with even greater stakes. The comic book version of this tale was epic, and saw Earth's Mightiest Heroes travel into outer space to put an end to the war before the Earth was torn apart by it.
Seeing whatever form this team takes in Avengers 5 also in those very different surroundings could be a lot of fun, especially if it's Captain Marvel who leads them into battle.
"Secret Invasion" being adapted in Captain Marvel 2 would set the stage for this, and an all-out war with the spotlight put on characters like the Supreme Intelligence, and perhaps even X-Men related supporting players like the Shi'ar Empire and Starjammers, would make for a jaw-dropping feature.
