It was a shock to Marvel Fans everywhere when Captain America himself was able to lift Thor's hammer in the movie, 'Avengers: Endgame.' Up until now, none of the other Avengers on the roster have been deemed "worthy" enough to pick up Mjolnir. Except for Thor himself, of course. Well, in Endgame, Cap apparently built up enough worthy points that he was able to grasp Thor's hammer and help fend off Thanos's attack. And it turns out, Cap always had the power all along.
