In a fanfic, there could be a plot where Natasha is poisoned and the only antidote can be created by Bruce using his knowledge of biochemistry. But he has to do it while keeping the Hulk in check. As he races against time, Natasha's condition worsens. This creates a tense situation that tests their relationship and shows how much they mean to each other. They also share some tender moments during this difficult time.
One idea could be a story where Bruce and Natasha are on a mission together in a remote location. They have to rely on each other's skills to survive. Bruce uses his scientific knowledge to figure out a way to stop a dangerous experiment gone wrong while Natasha uses her combat skills to protect them from the threats around. Their relationship gradually deepens as they face challenges side by side.
Another theme is redemption. Natasha might see helping Bruce control the Hulk as a way to redeem herself for her past actions. And Bruce might see Natasha as a chance at a normal life, which is a form of redemption for him. It's a complex interplay that is explored in a lot of the fanfictions.
The fanfiction 'Banner and Romanoff: Unlikely Allies' is also quite good. It starts with their professional relationship in the Avengers and then slowly evolves into something more. It has some really interesting character interactions and a well - paced plot that keeps you engaged.
The love story of Bruce and Natasha was captivating because of their mutual growth. Bruce learned to trust more because of Natasha, and Natasha found a different kind of purpose in being with Bruce. They both had their own demons. Bruce with his fear of the Hulk getting out of control and Natasha with her past as a spy. But together, they seemed to be able to face those demons better. It was like two broken pieces fitting together to form a whole. Their relationship also had an air of mystery as they were both so different, and it was exciting to see how they would interact each time.
Their love story began with understanding. Natasha saw beyond the Hulk in Bruce. She knew he was a brilliant scientist with a good heart. Bruce, in turn, saw Natasha's strength and vulnerability. They had a bond that grew over time. For example, in some missions, they relied on each other's skills. Their relationship was about more than just romance; it was about two people finding solace in each other in a world full of chaos and danger.
Maybe she's a congresswoman fighting for the rights of superhumans or former spies. She could be in the middle of political intrigue, where her past secrets are at risk of being exposed and she has to use her wits to keep them hidden while still doing her job in Congress.
A third plotline might involve a situation where one of them is in danger, and the other has to go to great lengths to save them. For instance, Natasha gets captured by a powerful enemy. Clint then uses his tracking skills and knowledge of Natasha's whereabouts to mount a solo rescue mission. Along the way, he reminisces about all their past missions and how much Natasha means to him.
One possible plotline could be that Natasha is kidnapped by a rival organization seeking to extract information from her about S.H.I.E.L.D. secrets. They might try various forms of interrogation, but Natasha, being the tough spy she is, manages to hold out and start planning her escape. Another could be that she's kidnapped by someone with a personal vendetta against her past as a Black Widow, perhaps a family member of someone she killed during her assassin days. They want to make her pay for her past actions.
