Well, a major theme is loyalty. They were loyal to each other, their country, and their friends. The idea of a love that transcends different worlds or situations is also quite common. Since Steve was frozen for a long time and Peggy had to live in a different world after his 'death'. Another theme is the struggle between duty and love. Both had important duties, but their love for each other was also very strong.
Sure. One popular Steve and Peggy fanfic is 'Agent Carter's Journal'. It delves deep into Peggy's thoughts and her relationship with Steve in a really interesting way. Another one is 'A Different Time' which imagines how their relationship could have developed if certain events in the Marvel universe had been different. There's also 'Steve and Peggy: Reunited' which has a heart - warming plot about their reunion after a long separation.
Often, there are themes related to their individual personalities. Howard's charm and Peggy's strength can be highlighted. For instance, a fanfic might show how Howard uses his resources to help Peggy achieve her goals while Peggy in turn helps Howard become a better person. It could also involve themes of adventure where they go on missions together, facing various challenges along the way.
There are many fanfic communities out there. You could also check out FanFiction.net. Maybe look for tags related to Howard and Peggy from the relevant fandom. It's possible that other fans have written interesting stories about them. Just keep in mind that the quality can vary widely among different fanfics.
One great Bucky x Steve fanfic is 'A New Beginning'. It delves deep into their relationship post - Avengers events, exploring how they reconnect and heal together. The characterizations are on point, making it a very engaging read.
I really like 'Steve x Eddie fanfic' like 'Hearts in Harmony'. It delves deep into their personalities and how they complement each other. The way the author writes their interactions, especially the small, tender moments between them, is just amazing. There's also 'Facing the Unknown' which is set in a post - apocalyptic world and shows how they rely on each other to survive.
Friendship is a very common theme. Despite their differences, they come together and form a strong bond. Another theme is redemption. For example, Bucky might be seeking redemption for his past actions, and Tony and Steve play a role in that process.
A good Bucky x Steve fanfic often has well - developed characters. It should stay true to their personalities from the MCU or comics. For example, Bucky's struggle with his past and Steve's unwavering loyalty.
