Don't forget about the other characters in both universes. In the Harry Potter world, you have Hermione, Ron, and all the professors who could play important roles in the fanfic. In the Hulk's world, there are characters like Tony Stark who could potentially make an appearance. You can use these characters to add more depth and complexity to the story. Also, think about the themes you want to explore. It could be about friendship, power, or the clash between science and magic. And make sure to write in a way that is engaging and keeps the reader wanting more.
First, you need to decide on the basic plot. Will it be a story where they meet in one of their worlds, or will it be a new world entirely? Then, think about how their personalities will interact. Bruce is a brilliant scientist with a temper problem, while Harry is a brave and determined wizard. You can create interesting scenes based on their different skills and mindsets. For instance, Bruce could use his scientific knowledge to analyze a magical phenomenon, and Harry could use magic to protect Bruce from danger.
Another fanfic concept could involve Harry Potter somehow ending up in Bruce Banner's world. He might be there to learn about modern Muggle technology and end up meeting Bruce. Together, they could face a threat that requires both magic and scientific knowledge to defeat. For example, a villain who is using both dark magic and advanced technology to cause chaos.
The unique aspect is the combination of two very different worlds. Harry Potter's world is full of magic, wands, and spells, while Bruce Banner's world is about science and the struggle with the Hulk. In the fanfic, we see how these two elements can co - exist, like how Banner's scientific mind might view magic, or how magic could potentially be used to control the Hulk.
The plot could start with Bruce Banner somehow ending up in the wizarding world. Maybe a scientific experiment goes wrong and creates a portal. Once there, he meets Harry Potter. They initially have some misunderstandings due to their different backgrounds, but soon realize they can help each other. The main plot could revolve around a new threat to the wizarding world that requires both Banner's scientific knowledge and Potter's magic to defeat.
In fanfiction, Bruce Banner could save Harry Potter through his scientific knowledge as well as the Hulk's powers. Maybe there's a situation where a magical curse is spreading uncontrollably. Bruce, in his normal state, could analyze the curse using his scientific expertise and figure out a way to stop it. And if there are any physical manifestations of the curse that need to be dealt with, the Hulk could step in and use his strength to destroy or contain them. This would show a great combination of the scientific and magical elements in the story.
A fanfic about Bruce Banner and Harry Potter could be really interesting. Maybe Bruce Banner could be a wizard who has the Hulk - like abilities as a magical manifestation. He could use his strength to protect Hogwarts from dark forces, like Voldemort's followers. It could also explore how the scientific mind of Banner would interact with the magical world of Harry Potter, perhaps he tries to find a scientific explanation for magic.
Perhaps Bruce Banner adopts Harry Potter after the events at Hogwarts. He takes Harry to the world of science, showing him things like advanced laboratories and scientific research. Harry, in turn, shows Bruce the wonders of magic. Their bond grows as they learn from each other, and together they face new threats that combine elements of both the magical and scientific worlds.
Harry is brave and determined. Bruce is intelligent but often hesitant due to his fear of the Hulk. Harry might encourage Bruce to be more confident. He could say things like 'You have so much power within you, don't be afraid to use it for good.'
Fem Harry Potter might be initially cautious around Bruce Banner, especially if she witnesses his transformation into the Hulk. She could use her magic to try and calm him down when he's in a Hulk - rage. Bruce, on the other hand, would be fascinated by Harry's magic. He might study it scientifically, trying to understand the principles behind it.
First, think of a unique plot. Maybe Bruce is trying to find a cure for his Hulk - ness using lemons. Then, develop the characters. For Bruce, you need to capture his intelligence and his internal conflict. As for the lemon element, give it a purpose. It could be a symbol of purity in his chaotic life.
There's a fanfic where Bruce Banner is a visiting scientist at Hogwarts. In the story, his scientific knowledge clashes and also meshes with the magic of the wizarding world. It shows how the two different forms of knowledge, Muggle science and magic, can interact. This 'Harry Potter Bruce Banner fanfic' is really thought - provoking and gives a fresh take on both universes.
