There could be a fanfiction where Natasha's sister has a split personality. One side is very meek and mild, while the other is wild and 'crazy'. The Avengers find it hard to deal with her at first. But as the story progresses, they discover that her 'crazy' side has a deep - seated knowledge of an ancient threat that is about to befall the Earth, and they need to work with both sides of her personality to stop it.
One possible fanfiction could be about Natasha's sister having some sort of superpower that makes her seem 'crazy' to the outside world. For example, she might have the ability to see alternate dimensions and her ramblings about those other worlds are misconstrued as insanity. In the story, the Avengers could initially be wary of her but then come to realize her power is actually quite useful.
Maybe Natasha's sister was experimented on by the same organization that Natasha escaped from. This led to some mental instability. In the fanfiction, Natasha tries to help her sister regain her sanity while also protecting her from the enemies who want to use her sister's new - found and unstable powers for their own evil purposes.
One possible fanfiction could be about Natasha's sister joining the Avengers. Maybe she has some unique powers like the ability to control minds on a small scale. She could start as a bit of an outcast, but as the story progresses, she earns the respect of the team through her courage in battles.
The plot could revolve around Natasha's sister being a secret weapon. She might have been locked away for years because of her uncontrollable powers. When she is finally set free, she has a hard time adjusting to the normal world. The Avengers, led by Natasha, try to train her and help her control her powers. Along the way, they face many challenges, like villains who want to capture her sister for their own gain.
She could be a super - spy too, but on a different side initially. Maybe she was brainwashed by a shadowy organization. Natasha then has to fight her sister while also trying to bring her back to her senses. It would be a story full of action and emotional turmoil.
One great Natasha Romanoff Avengers fanfiction is 'Red Room Echoes'. It delves into her past in the Red Room and how it still haunts her during her time with the Avengers. The story is well - written, with great character development.
In many of these fanfictions, Natasha's character is explored through her vulnerability when she's sick. For example, in some stories, we see her usual tough exterior crack, revealing her fear and dependence on her team mates, which is a side of her we don't often see in the movies.
In fanfiction, the Avengers' reactions to Natasha's past could vary greatly. Clint, being her close friend, might already know a lot but still be affected by new revelations. He could be a bit sad and say 'Nat, you've been through so much alone'. Bruce might be hesitant in his reaction. He might stutter a bit and say 'Natasha, your past is... quite something. But it doesn't change how I see you'. And Natasha herself would be on edge, waiting for their reactions, hoping for acceptance.
One great 'Avengers Steve and Natasha fanfiction' is 'The Red and the Blue'. It beautifully explores their relationship in the context of their Avengers duties. The author does a wonderful job of showing their mutual respect and the unspoken connection between them.
In a fanfiction scenario, Natasha and Steve's relationship could develop in a way that leads to her pregnancy. Maybe it starts with a deep emotional connection during a difficult mission. As Natasha goes through the pregnancy, she struggles with her identity as a former assassin becoming a mother. Steve, on the other hand, draws from his own values of family and protection. The birth could be a moment of great joy and new beginnings for them, symbolizing a new chapter in their lives not just as individuals but also as a couple within the Avengers family.
To develop kid Natasha, you could focus on her backstory. Maybe she was an orphan and had to learn to fend for herself at a young age. This would make her resourceful and street - smart.
First, they would need to figure out if it was a trap. But assuming it's not, they could divide into teams. One team, like Ant - Man and Wasp, could infiltrate the place in a stealthy way. Meanwhile, Doctor Strange could use his magic to create illusions and misdirect the captors. The Avengers would have to work together, combining their different powers and strategies to rescue Natasha successfully.
