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.
Perhaps in a post - Endgame world, Captain Marvel and Black Widow find themselves in an alternate dimension where they have to team up to find their way back home. Along the way, they learn more about each other's pasts and form a deep bond of friendship. Black Widow could teach Captain Marvel some of her hand - to - hand combat techniques that are more stealth - based, and Captain Marvel could show Black Widow how to better use her environment when in a fight due to her enhanced senses.
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.
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.
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.
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.
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.
They could start as rivals. Maybe they are both vying for a top position in S.H.I.E.L.D. or in a new superhero alliance. As they compete, they begin to see the value in each other's skills.
A really interesting fanfiction idea could be a pre - Avenger days story. Black Widow is on a mission for SHIELD and Captain Marvel, who is relatively new to Earth, gets caught in the middle of it. Black Widow initially suspects Captain Marvel of being a threat. But as they interact more, they realize they have common goals. It could show their character development and how they could have potentially influenced each other's growth even before the big team - up in the Avengers.
One idea could be a story where Captain America and Captain Marvel team up to face a new cosmic threat that's headed towards Earth. They have to combine their unique skills, with Captain America's strategic mind and combat experience on the ground, and Captain Marvel's incredible cosmic powers in space battles.
Begin by choosing a theme for your fanfiction. It could be friendship, rivalry, or a shared goal. If it's about friendship, you could write about how they support each other through tough times. They could be facing a powerful enemy or dealing with internal conflicts in the Avengers. Then, develop their characters further in your story. For instance, show how Captain Marvel's cosmic powers can be used in creative ways to help Black Widow in her more down - to - earth combat situations. Write in a way that makes the reader feel like they are part of the story, with vivid descriptions and engaging dialogue.
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.
