One possible fanfic could be 'The Battle's Toll' where Captain America endures a serious injury during a fight against a powerful new villain. The author might focus on his struggle to recover and how his team copes without his full strength for a while.
To portray his emotional hurt, they may show his reactions to difficult situations. If he's betrayed, he might have a look of shock and disbelief on his face. Writers can also use his internal monologue. For instance, 'Steve thought to himself, how could he have been so wrong about his friend? The pain of this betrayal cut deeper than any physical wound.' This shows his emotional turmoil.
One popular example could be those that focus on Captain America getting physically hurt during a battle and his struggle to recover. It might show his determination in the face of pain. Another could be fanfics where he is emotionally hurt, like when he has to make tough decisions that go against his moral code. For instance, in some fanfics, he might be forced to choose between saving a large number of civilians or a close friend, which causes him great emotional turmoil.
Dr. Bruce Banner could play an important role. His scientific knowledge could be used to analyze Captain America's condition and come up with solutions. In some fanfictions, he might even find a way to enhance Captain America's healing abilities. Also, Thor, if he's around, could use his Asgardian magic or knowledge to help in the healing process, perhaps by bringing some rare Asgardian herb or elixir that has healing properties.
One common theme is the struggle to overcome physical injury. Captain America is often depicted as superhuman, but in these fanfictions, his human side shows through when he has to deal with pain and the process of healing.
Well, if we look at such a scenario in fanfiction, it could be a way to give Spiderman a character - building moment. When he gets hurt saving Cap, it can lead to some great internal monologues. He might question his own abilities or reaffirm his commitment to being a hero. And it also gives the author a chance to create some interesting interactions between Spiderman and the other characters as they react to his injury.
Writers create tension by emphasizing the severity of Captain America's injury. If it's a physical injury, they might describe the blood, the pain, and his struggle to even move. For example, if he has a broken leg, the way he tries to stand up and keep fighting can build tension. The reader is on edge, wondering if he can actually do it.
Well, in some fanfics, they might make Captain America seem like a jerk to create an interesting plot twist. Maybe they show him being overly self - righteous or making bad decisions that go against his usual heroic image.
The Night King could be a great antagonist. His army of the dead and his own powerful magic would pose a huge threat to Captain America. Cap's used to fighting human foes, but the Night King is something entirely different.
He could also meet Odin. Odin might view Captain America as an interesting mortal from Midgard and might have some words of wisdom or a task for him to complete during his stay in Asgard.
