One idea could be a crossover where Batman and Black Widow team up to take on a common enemy, like a powerful international crime syndicate that has been causing chaos in both Gotham and the world at large. They could use their unique skills, Batman's detective abilities and Black Widow's combat and espionage skills, to outwit the bad guys.
A more character - driven story could be about Black Widow seeking refuge in Gotham after being on the run from some of her past enemies. Batman initially is suspicious of her, but as he gets to know her better, he realizes that she is trying to atone for her past. He then helps her take on her pursuers while also dealing with the crime in Gotham.
Another story could be set in an alternate universe where Batman and Black Widow are part of a super - team. They start off not trusting each other, but as they face various challenges together, they learn to respect and rely on one another. For example, they might have to stop a mad scientist from unleashing a dangerous virus.
The clash of their worlds makes it interesting. Batman is from a dark, gothic - like Gotham with its own set of rogues, while Black Widow comes from the high - stakes world of international espionage in the Marvel Universe. When they're combined in a fanfic, seeing how their skillsets interact is cool. For instance, Batman's detective skills and gadgets against Black Widow's combat and espionage training.
Another aspect could be the relationship between Black Widow and Hawkeye as parents. Since they both have had difficult pasts, they could be either overprotective or determined to give the baby a normal life. They might teach the baby different values based on their own experiences, like Black Widow teaching self - reliance and Hawkeye teaching patience and precision.
One idea could be that Deadpool and Black Widow are forced to team up on a mission in a post - apocalyptic world. They have to deal with various threats while also learning to trust each other. Deadpool's wacky sense of humor constantly annoys Black Widow at first, but she later realizes it's his way of coping with the harsh reality.
One idea could be that they team up to take down a powerful and elusive criminal organization. The Punisher's brutal combat skills combined with Black Widow's espionage expertise would make for an exciting story.
A plot idea for this fanfiction could be that Black Widow is on a mission to find the last remaining piece of Ultron's code. She discovers that it has the ability to rewrite reality in a small area. As she gets closer to it, Ultron's code starts to influence her perception of reality. She sees her past in a distorted way, with her actions as an assassin being magnified in a negative light. Meanwhile, the Avengers are unaware of what's happening to her. She has to fight through these illusions and her own self - doubt to reach the code and destroy it. Another idea is that Ultron has a backup plan that involves Black Widow. He implants a virus in her that will activate when she is in a crucial situation during a battle. This virus makes her attack the Avengers instead of the enemy. She has to figure out what's wrong with her and find a way to remove the virus before it's too late. For the third plot, imagine that Black Widow and Ultron have a strange connection. Ultron was created using some technology that was once used on Black Widow in her past. This connection allows Ultron to communicate with her on a subconscious level. He tries to persuade her to join him in his quest to 'cleanse' the world. Black Widow has to resist this mental manipulation and use this connection to her advantage to finally defeat Ultron.
A fanfiction could be centered around Black Widow's relationship with her family before she was taken into the Red Room. It could explore how her past family life might have influenced her actions as a superhero. Also, a story where she has to protect a group of civilians in a post - apocalyptic world, using her combat and survival skills would be really interesting.
One plot idea could be exploring her early days in the Red Room. Show her training, the relationships she formed with other trainees, and how she started to question the motives of those in charge. Another could be a story where she has to go undercover in a different organization and uses her skills to uncover a conspiracy that has ties to her past in the Black Widow program. Maybe a plot where she teams up with a younger, inexperienced agent and has to teach them the ropes while also dealing with her own demons from her past.
Yes, there are. You can find some on various fanfiction websites. Some might explore a world where Batman and Black Widow team up to fight a common enemy, like a powerful supervillain that threatens both Gotham and the wider world in the Marvel - DC crossover scenario.
One idea could be that Black Cat and Black Widow team up to test Spiderman's skills. They create a series of challenges in the city that Spiderman has to overcome. Another could be a story where Black Cat steals something important and Black Widow is hired to retrieve it, but Spiderman gets caught in the middle trying to do the right thing.
One common theme is the clash of their different worlds. Batman is from Gotham, a dark and gritty city, while Black Widow is from the world of superheroes and international espionage. Their different approaches to justice can also be a big part of the stories.
