Captain America is the patriotic marvel comic boom super hero. He is also the most badass character in the Endgame here is why:
1)After the snap when the other avengers are either on a killing or drinking spree(Hawkeye and Thor). Captain America hosts a self-help group with other survivors.2)Fights his own past self
Who wouldn’t want to see Captain America fight Captain America.
3)Lifts Thor’s hammer
WHICH IS VERY VERY VERY COOL
Captain America summons Thor’s old weapon, Mjolnir, and proceeds to beat the living shi* out of Thanos with it, much to the audience’s delight.He continues to wield it all the way to the movie’s finale.
4)Lifts stormbreaker WHICH MAY BE COOLER THAN HIM LIFTING MJOLNIR
At one point Cap commands the hammer to him but gets Stormbreaker instead. Thor commands Mjolnir here but then looks at Cap and says “yeah, let’s switch” and they exchange Hammers.
5)Goes back in the past to to put back all the stones and stays there with the love of his life.
His love for Carter that prompts Captain America to do a hero handoff to his friend Sam (the Falcon) and retire from the Avengers
And finally, He Has America’s Best Ass
