A common theme is the idea of an unlikely friendship. Bella, who might be seen as a more delicate character, and the Hulk, a brute force, coming together and forming a bond. Another theme is adventure. They often go on quests or face challenges together.
One of the themes is self - discovery. Bella discovers new sides of herself when she's with the Hulk, and the Hulk also learns more about his own emotions. Also, the theme of acceptance is there. They accept each other's differences, whether it's Bella accepting the Hulk's power or the Hulk accepting Bella's more gentle nature.
Power and vulnerability is a big theme. The Hulk has all this physical power, but often has emotional vulnerability. Bella may not have the same physical strength but has mental strength. In fanfiction, they often balance each other out in terms of these aspects. There's also the theme of protecting one another, which is quite prevalent as they face threats together.
One common theme is the exploration of their differences. Hulk's raw power and Tony's intellect are like two opposite poles, and fanfictions often play with how they can either clash or complement each other. For example, in many stories, Tony tries to use his tech to control or understand the Hulk better.
One common theme is the exploration of power dynamics. When the Hulk crosses over with other characters, it's all about how their powers compare and interact.
Another theme is the power of friendship. They come from very different backgrounds, but in fanfiction, they often form a strong bond. They support each other in battles and in personal growth. Like when Black Widow is in a tough situation and the Hulk comes to her rescue, showing that they have each other's backs.
A common theme is the clash of two different worlds. The magical world of Harry Potter and the super - powered world of the Hulk. This often leads to misunderstandings and comical situations as the characters from each world try to figure out the other.
Another theme is redemption. Sometimes the Hulk is portrayed as a character seeking redemption for the destruction he's caused, and Black Widow helps him on that journey. It's about how they can find a new purpose together. A lot of fanfictions also play with the idea of them being outsiders in the Avengers group, and how they form a special bond because of that.
Another common theme is the power dynamics. Hulk's raw power and Tony's technological power can create an interesting dynamic. Sometimes in the fanfictions, they compete in a friendly way, which eventually leads to a deeper understanding and love. Also, the theme of redemption can be present, where they help each other overcome past mistakes or traumas and in the process, fall in love.
Power and responsibility is also a big theme. The Hulk has such immense power, and in Civil War fanfictions, writers often explore how he should use that power during this time of division. Does he use it to stop the fighting? Or does he add to the chaos? It's a complex exploration of his power in the context of the Civil War.
Friendship and camaraderie is also a big theme. Despite their differences, they come together to fight for a common good. In many fanfictions, they start off not liking each other much but as they face challenges side by side, they develop a deep bond. It's like a story of two opposites learning to get along and respect each other.
A frequent theme is 'partnership'. They are both part of the Avengers, and fanfictions often explore how they work together in different situations. For example, in some stories, they are the last line of defense against a powerful threat. Also, the theme of 'forbidden love' can be found in some 'the hulk and black widow fanfiction'. Their different natures and the potential complications within the Avengers team can make a love story between them seem both exciting and challenging.
A common theme is self - acceptance. The character has to come to terms with their new form, which can be a big struggle. They might initially hate the way they look or feel out of control during the transformation.
