Another concept could be a time - travel fanfic. Black Widow somehow gets sent to a time when Captain Marvel was just starting out as a hero. Black Widow then has to train the younger Captain Marvel and help her unlock her full potential while also trying to find a way back to her own time.
One idea could be that Captain Marvel and Black Widow are on a mission together to infiltrate a powerful and secretive organization. They have to rely on each other's unique skills, with Captain Marvel using her super strength and flight to get them in and out of tight spots, while Black Widow uses her espionage expertise to gather intel.
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.
Maybe Captain Marvel loses her powers temporarily due to some sort of alien technology. Black Widow then has to protect her and find a way to get her powers back. But it turns out that the one behind the power loss is someone they both trusted, like a fellow Avenger who has been mind - controlled.
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 plot idea could be that Black Widow and Captain America are on a secret mission together in a war - torn country. They have to rely on each other's skills to infiltrate an enemy base and retrieve a dangerous weapon. Another could be a story set in the past, where they first meet during their training days and form an unlikely friendship that develops over time. Maybe a plot where they are both framed for a crime they didn't commit and have to work together to clear their names while also uncovering a larger conspiracy within S.H.I.E.L.D.
A prevalent theme is also power dynamics. Captain Marvel has immense superpowers, while Black Widow is a highly - skilled human. Fanfictions often play with how these different power levels interact. For example, they might face a situation where Captain Marvel's powers are nullified, and Black Widow has to step up and protect her, reversing the expected dynamic. Additionally, redemption and self - discovery are themes. Both characters have complex pasts, and fanfictions can explore how they help each other come to terms with their past actions and grow as individuals.
No. In the Marvel Cinematic Universe, Captain America has his own love interests like Peggy Carter, and Black Widow has her complex relationships but not a romantic one with Captain America. Their relationship is more of comrades and friends, fighting side by side in many battles.
A great fanfiction could be set in a post - Endgame world. Captain Marvel has been away for a long time and when she returns, she finds that Black Widow's sacrifice has left a big hole in the Avengers. She decides to honor Black Widow's memory by training a new generation of female heroes, inspired by Black Widow's skills and tenacity.
No. While Captain America and Black Widow have a great relationship, it's not a romantic one. They have different love interests within the story. Captain America has his connection with Peggy Carter, and Black Widow has her own complex relationships. Their story together is mainly about teamwork and friendship in the face of danger.
One idea could be a story where Captain Marvel and Valkyrie team up to fight a new, powerful enemy that threatens the entire universe. They start off not getting along due to their different fighting styles and personalities, but as they face challenges together, they learn to respect and rely on each other.
