One common theme is their relationship development. Since they both have complex personalities in the Marvel universe, fanfictions often explore how they get closer and understand each other better.
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.
Redemption is also a big theme. Given her complex past, many fanfictions focus on her journey to become a better person. This could be through helping others, making up for past wrongs, or finding a new moral code to live by. Fanfics might show her working with charities or saving people in ways that she feels atone for her past actions.
Love and friendship are also prevalent themes. He might find an unexpected friend or fall in love in ways that are different from the original story. These relationships help shape his character further and add more depth to the fanfiction.
One common theme is exploration. Just like in the original, fanfictions often involve the characters exploring new planets or star systems.
One common theme is the clash of cultures. Naruto comes from a world of ninjas with its own set of values and traditions, while Natasha is from the high - tech and complex Marvel universe. Their different ways of thinking and acting often lead to interesting situations in the fanfiction.
One common theme is mentorship. Since Natasha is more experienced, she often takes on the role of guiding Spiderman in many fanfictions. Another theme is teamwork. They are both part of the Avengers, so stories often center around them working together to achieve a common goal.
A third common theme is personal growth. Both characters have their own traumas and pasts. When they meet, they often influence each other in a way that helps them grow. For instance, Naruto's positive outlook might help Natasha deal with her darker past, and Natasha's experience in a more complex and political world could make Naruto more aware of the bigger picture outside of his ninja village.
Another theme is adventure. Since Bruce Banner's life is full of danger and unpredictability, the OC gets dragged into all kinds of adventures. They might be on the run from bad guys who want to use the Hulk's power or exploring new scientific breakthroughs together.
Another theme could be his relationship with his family in his early years. Maybe how his parents' influence shaped him or how he coped with any difficulties in his family life. In some fanfictions, his family might play a crucial role in his later transformation into the Hulk. It's interesting to see how different writers envision these relationships.
One common theme is the exploration of femininity in a scientific and superhero context. Since Bruce Banner is known for his scientific genius, a female version might face different challenges or opportunities in the scientific world. Another theme could be relationships. How would a female Bruce Banner interact with the other Avengers? Would her relationships be different from the male version? For example, romantic relationships might be portrayed in a new light.
