A good example of a man surpassing fear and gaining competence in the MCU, fittingly enough, is the first Iron Man but it's also an interesting take on the formula
Tony Stark is already fearless and competent. He already has what most men would want and would consider a hero and he's forced to face his actions and decide that he may be wrong
Tony is thrown into a terrifying scenario. Nikka wakes up in a cave with no heart, and a terrorist is telling him to build this missile or die. Tony has to surpass that fear and test his competence if he wants to survive. Tony builds the suit, accessing a new level of competence and escapes
Tony is now faced with the fear of considering that he's a death merchant. He wants to be better so he defiantly shyts down the military weapons. It's not defiance just for the sake of. He builds the suit, scenes of trial and error to show him GAINING competence. This part is very important and the reason characters like Riri don't work. We don't see her learning or being challenged. It ain't enough to just show an uncontested genius
Tony is forced out of his comfort zone and his introspection forces his him to become a hero. He goes throughout the movie, and the MCU, asking himself the same questions to varying results. His desire to help the world has done great things but also created shyt like Ultron. His competence is always challenged and he rises to the occasion. THIS is what makes heroes boys aspire to be
Conquering fear and gaining competence is a foundational aspect of what men require in stories because manhood in real life is defined by those same traits. It's the reason we love Goku and 80s action movies. It's the reason nikkas get hype at Rocky training montages
When you remove this key element from these movies you end up with the bullshyt we have now. And you lose boys and men
