Just gonna go right off the bat and say that, NO! Nobody can replace the MCU Trinity. They were literally made for being Marvel’s Trinity.
But of course, that doesn’t change the fact that a few changes have to be made to the role and of course, the Avengers are not dead yet. In Endgame, most heroes were declared as Avengers.
Keep in mind, what i’m about to say is solely based on a fanboy’s opinion. Basically, i’m not going to predict who’s going to be who, i’m just out here giving choices.
First the leader of the Avengers,
CAPTAIN AMERICA, The Sentinel of Liberty.
Steve Rogers is basically the commander, he is the one that gives orders during the battle and delegate roles. Who could take over his job? I know this is going to sound unpopular but i can see Hawkeye as the leader.
If anybody would be more deserving of the leadership role right now, it’s Hawkeye. He’s one of original six Avengers, he’s more familiar with how the team works.
I can see a lot of Cap in Hawkeye, he puts out good examples.
Hawkeye is a soldier, just like Cap. Plus, he was trained by Cap.
Hawkeye has been overshadowed by his fellow Avengers throughout the whole franchise and i honestly believe, this could be a chance for Marvel to prove that he is more than he seems (though, i know that it may be the end for him in the MCU since he would be training his daughter to pass on his mantle to her in the new Hawkeye show).
And now,
THOR, the God of Thunder.
The……
He is basically the powerhouse of the trio. Now i think that the answer is pretty clear, Captain Marvel.
She’s really powerful, just like Thor.
Now i know that Captain Marvel doesn’t really stay on Earth, she travels across the whole galaxy but so did Thor, i mean Thor’s home literally wasn’t on Earth and he traveled to a lot of planets.
But he was there most of the time when the Avengers needed him. So i can definitely see Captain Marvel taking up his role.
And last but not least,
IRON MAN, Genius, billionaire, playboy, philanthropist.
This summarize his role, he’s basically the father/financier of the Avengers.
Who can take up his role? In my opinion, it would make sense for it to be T’Challa a.k.a the Black Panther.
He’ll have more than enough money to take care of the Avengers, i mean he is a freaking king. There are a few similarities between both, both are genius and billionaire. Now i know many would want him to be the leader of the Avengers considering Panther is really good leader and he has a good leadership chemistry with Cap
But i feel like Tony Stark’s role would apply more to him.
