A really interesting plot could be that Natasha and Steve find a lead on a powerful weapon that Ultron is after. They race against time to secure it before Ultron does. Along the way, they encounter various challenges and enemies. Their different fighting styles and personalities come into play as they strategize. Steve's more straightforward and honorable approach might clash with Natasha's more devious spy tactics at first, but they learn to combine their strengths. As they get closer to the weapon, they also realize that there is a deeper conspiracy behind Ultron's actions that involves some of their old enemies.
One plot idea could be Natasha and Steve having to go undercover together during a mission related to Ultron's early schemes. They could pretend to be a couple, which would lead to some awkward yet heartwarming moments as they navigate their feelings while also trying to stop Ultron. Another idea is that Natasha discovers a hidden past of Steve that is somehow connected to the creation of Ultron and they have to deal with the revelations together.
One idea could be exploring the backstories of the new characters introduced in the movie in more depth. For example, Wanda and Pietro Maximoff. Maybe write about their lives before they got their powers.
A great plot idea is Wanda having to face off against a new villain who is specifically targeting her because of her powers. This villain could be trying to manipulate her powers for their own evil purposes. Also, a plot where Wanda teams up with other female superheroes from the MCU to form a sort of sisterhood and take on threats that are being ignored by the male - dominated superhero groups. It would show her growth and ability to form new alliances.
Their relationship could develop through shared experiences. For example, fighting side by side against Ultron's forces would build trust. Steve might admire Natasha's skills and her ability to adapt, while Natasha could be drawn to Steve's unwavering sense of justice.
One idea could be exploring the backstory of a minor character in the movie. For example, what if one of the Sokovian citizens had a special power that was awakened during the chaos of the battle. Another could be a different take on the relationship between Vision and Wanda. Maybe Vision struggles more with his new - found emotions and Wanda has to help him understand humanity better. Also, a fanfic could focus on what would happen if Ultron had a change of heart midway through his plan due to some unforeseen event or encounter.
Well, a cool plot might be that Wanda accidentally creates a rift in time while trying to master her powers. She then has to team up with a younger version of herself to close the rift before it causes chaos across the multiverse. Or perhaps she forms an unlikely alliance with a villain from the Age of Ultron who has a change of heart. They then work together to stop a new, more powerful enemy that is emerging. Also, a story where she uses her powers to enter the minds of the Avengers and discovers their deepest fears and insecurities, which she then uses to strengthen their bond.
Another storyline could be about their growing feelings for each other in the backdrop of the chaos of Age of Ultron. Maybe Natasha is injured during a battle, and Steve is forced to confront his true feelings as he takes care of her. This could lead to some tender moments between them and a deeper exploration of their connection.
A plot could revolve around a kid Natasha joining the Avengers on a time - traveling adventure. They go back in time to stop an event that could change the future of the Avengers. Along the way, Natasha has to use her wits and natural skills to overcome various obstacles, and she forms a special bond with the other Avengers members during this journey.
Steve's straightforwardness and Natasha's secrecy can be both a point of clash and complement. Steve may not always understand Natasha's need to keep things hidden, which can lead to arguments. But in a mission, Natasha's ability to keep secrets can be an asset, and Steve's honesty can be a refreshing change for her. They balance each other out in many ways, like two sides of a coin. Steve's idealism gives Natasha hope, and Natasha's realism keeps Steve grounded in the real - world implications of their actions.
Perhaps a fanfiction could explore what would happen if Spiderman was the one to first discover a major flaw in Ultron's plan. Since he's a street - level hero with a different perspective from the more global - minded Avengers, he might see something that they miss. His attempts to convince the Avengers about this flaw could create a lot of drama and action in the story.
In the 'Avengers Watch Age of Ultron Fanfiction', the interactions between the Avengers themselves can be really engaging. They could be discussing their past mistakes during the events of the movie, like how Tony Stark's creation of Ultron led to so many problems. This kind of self - reflection might be more intense in the fanfiction compared to the movie.
