Another story could be about Sharon Carter helping Captain America adjust to the modern world. She could introduce him to new technologies and cultural aspects while also reminiscing about the past. This would be a story of friendship and mutual understanding, showing how they support each other in different ways.
One appropriate story could be about their teamwork in a mission. They work together to take down a group of bad guys threatening a city. Captain America uses his shield while Sharon Carter uses her combat skills and intelligence to outwit the enemies.
A possible storyline is Sharon Carter getting involved in a time - travel adventure similar to what Steve Rogers had. She might end up in a different era and has to use her skills and wits to survive and find her way back. Along the way, she could discover new things about Captain America's past that were previously unknown. Or perhaps a story where she teams up with other superheroes to take on a new threat, but she's constantly haunted by her relationship with Captain America and how it affects her actions in the team.
Another storyline might involve Sharon Carter getting kidnapped and Captain America having to rescue her. This would not only show his heroism but also his deep feelings for her. Along the way, he might have to fight his way through hordes of bad guys and overcome various obstacles.
No, Sharon Carter did not become Captain America in the comics.
Writing their relationship well means exploring the power dynamics. Captain America is a symbol, and Sharon is a strong agent in her own right. Show how she respects his position but also challenges him when necessary. Their relationship could be about mutual growth. For example, Steve could have taught her about leadership, and she could have taught him about modern society. Additionally, add some conflict. Maybe they have different views on how to handle a particular threat, which tests their relationship but also deepens it in the long run.
There are many great fanfiction platforms like Archive of Our Own (AO3). You can go there and search for Sharon Carter and Captain America stories. Filter the results to exclude any mature or sexual content tags. Usually, you'll find a lot of adventure - themed or character - study - type fanfics that focus on their relationship in a non - sexual way, such as stories about them teaming up to fight a common enemy or dealing with complex moral dilemmas within the Marvel universe.
Another plotline could be about Sharon helping Captain America adjust to the modern world. Maybe she takes him on a tour of modern technology and they bond over their shared love for justice. They could also be involved in a mystery where they have to use their different perspectives (Sharon's modern knowledge and Captain America's old - fashioned values) to solve it. This would focus on their friendship and mutual respect.
They also have positive interactions outside of battle. Sharon has been shown to support Captain America's moral decisions. She respects his values and they often have deep conversations about how to protect the world and uphold justice. Their relationship is based on mutual respect and a shared sense of purpose.
The theme of sacrifice is also quite common. Steve sacrificed his life (or so he thought) by crashing the plane. Peggy sacrificed her personal life to a great extent for the SSR and the fight against Hydra. Fanfics will often put them in new situations where they have to make more sacrifices. And then there's the theme of time. The fact that Steve was frozen for decades while Peggy aged is a rich area for exploration in fanfics. They deal with how time has changed them and yet how some things between them remain the same.
Stories about a wife's kindness, like how she volunteers in the community and helps the poor or the elderly. For example, she might spend her weekends at a local shelter, cooking meals for the homeless.
