Well, they might face challenges from the public eye. Captain America is seen as a symbol of America, and his marriage to a former Russian spy could cause some political and public relations issues. Also, their own insecurities could be a problem. Black Widow might worry that she's not good enough for Cap, and Cap might be concerned about protecting her from her past enemies. And of course, they both have very dangerous jobs, which could put a strain on their relationship as they constantly worry about each other's safety.
One challenge could be their different backgrounds. Captain America is from a more idealistic time, while Black Widow has a dark past in the Russian spy world. This could lead to some misunderstandings. Another is their different approaches to fighting. Cap is more of a straightforward fighter, while Black Widow uses her wits and stealth. It might be hard for them to always be on the same page during battles when they're married.
One possible plot could be that Black Widow is on a dangerous solo mission deep in enemy territory. Captain America, learning of her peril, rushes to her aid. He uses his shield to deflect incoming attacks and his combat skills to fight off the enemies one by one until he reaches her. Then they fight their way out together, with Captain America providing cover for the injured Black Widow.
Another possibility is a fanfiction set in an alternate universe. In this universe, Captain America and Black Widow are not part of the Avengers. Instead, they are partners in a detective agency. They solve crimes that are related to super - powered individuals, using their own unique abilities and intelligence.
In the fanfiction, their relationship could be complex. They've been through so much together as comrades in the Avengers. As parents, they might have different parenting styles. Captain America could be more open and idealistic, while Black Widow is more cautious and practical. But they both love their child deeply and work together to keep the child safe from the threats that come from their superhero lives. For example, when the child wants to join a mission too early, they have to work out how to handle it as a couple.
One great 'Black Widow and Captain America' fanfiction is 'Shadows of the Past'. It delves into their past missions together and how those experiences shaped their relationship. It has a great mix of action and emotional depth.
Perhaps a story where Black Widow is injured badly on a mission. Captain America refuses to leave her side and takes care of her. During her recovery, they have heart - to - heart conversations that lead to a new level of understanding and friendship, which then evolves into a romantic relationship.
One possible plotline could be that a new character enters the scene, perhaps a powerful and attractive superhero or agent. Captain America starts showing interest in this new person in a friendly way, but Black Widow misinterprets it as something more. She becomes jealous and starts acting cold towards Cap. Meanwhile, Cap is oblivious to her jealousy at first. As the story progresses, they have to work together on a mission and gradually realize their true feelings for each other through various challenges and misunderstandings.
In the comics, Captain America and Black Widow are not typically depicted as a couple. They have a professional relationship based on their roles as superheroes within the Marvel universe.
In fanfiction, the relationship between Captain America and Black Widow can be complex. Sometimes it's portrayed as a deep friendship with mutual respect. They've been through many battles together and understand each other's strengths and weaknesses on the battlefield.
