Well, it depends on different fan groups. Some might be interested in exploring different scenarios with Captain America, even if it involves him being 'sick' in the fanfic. But overall, it's not as mainstream as regular heroic portrayals of him.
A theme could be about the medical or scientific efforts to cure him. It could show how advanced or not so advanced the medical technology in the Marvel universe is. Maybe it involves some new characters who are experts in treating superhero - level ailments.
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.
There's also 'Captain America: Reborn'. In this fanfic, Steve Rogers has to face a new threat that is specifically targeting his ideals. It's a great read as it explores his unwavering beliefs and how he inspires those around him even in the face of seemingly insurmountable odds. It also has some unique interpretations of his powers and abilities.
Captain America could fit in by sharing his sense of morality and leadership. In the TOS universe, which often deals with complex moral and ethical dilemmas, his straightforward and noble values could provide a different perspective. He might be involved in diplomatic missions, using his charisma and integrity to negotiate with alien races. Also, his military experience could be applied to strategic planning during the crew's missions.
Well, it's hard to say who the 'best' is as it depends on personal taste. But some popular authors in the fanfic community often include those who have a deep understanding of the characters. For example, 'MarvelFan45' has written some really engaging stories that explore the relationship between Captain Marvel and Captain America in different scenarios. Their writing style is very descriptive, making you feel like you're right there with the characters.
Well, first of all, he has to adapt to the slower pace of life. In his own time, everything was so fast - paced. But now, in the past with Peggy, he has to slow down. He'll have to adapt to the fashion, the food, and the overall lifestyle. He might struggle a bit with not being able to use his high - tech gadgets. However, his relationship with Peggy will be his anchor. They'll start to build a life together, and he'll gradually become more comfortable in this new - old world. He'll learn to value the things that were important in that era, like family, community, and loyalty, just like Peggy does.
