With Infinity War and whatever the fourth Avengers film ends up being called, Marvel will be bringing Phase Three of its cinematic universe to a close sooner rather than later. While details on how this phase will end are still scarce, one thing we can be pretty sure of is that Avengers 4: The Dream Master will shake-up Earth's Mightiest Heroes in a pretty major way.
It's all but confirmed that at least one hero won't be making it out alive of Avengers: Episode IV- A New Hope and rumours of who it will be range from perpetual "oh yeah that guy" Hawkeye to big names like Captain America and/or Iron Man. One thing that's for sure though is that after Avengers and the Kingdom of the Crystal Skull, the team is going to have some slots to fill.
Luckily, the team has decades worth of members who could fill those boots so, with that in mind, let's take a look at some of the biggest Avengers from the comics who are just itching to make their MCU debut.
Any one of these characters would be a great fit for the team and could provide a fun and fresh new take on the Avengers going forward into Phase Four.
