How could Bruce Banner save Harry Potter in fanfiction?

Bruce's experience with being an outsider could resonate with Harry. Harry has always felt different, being a wizard in the Muggle world and then being 'the chosen one' in the wizarding world. Bruce, as a scientist who turns into the Hulk, is also an outsider. They could bond over this and help each other gain more confidence in who they are.

One idea could be that Bruce Banner is somehow transported to the wizarding world of Harry Potter. Maybe he arrives during a time of great danger, like when Voldemort is at his most powerful. Bruce's scientific knowledge could be combined with magic in unexpected ways. For example, his understanding of gamma radiation might interact with some of the more dangerous magical spells or potions. He could also form an unlikely friendship with Harry Potter. Harry could teach him about magic, while Bruce could show Harry some of the scientific concepts from his world.

If they meet, Bruce Banner might be really intrigued by the magic in Harry's world. He could see it as a new form of science. And Harry could be fascinated by Bruce's scientific knowledge. They might exchange ideas, with Harry showing Bruce how magic can do things like teleportation, and Bruce explaining some scientific concepts to Harry, like how gamma radiation works.

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.

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.

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.

One possible plot could be that they are brought together to solve a mystery that combines magic and science. Maybe a powerful artifact has been found that is both magically and scientifically complex, and their combined knowledge is needed to figure out how to handle it safely.

The story could explore how Harry's upbringing changes. Maybe he grows up in a world that's part wizarding and part scientific. He'd have to deal with the secrecy of both the wizarding world and his father's scientific experiments. His relationship with his friends at Hogwarts might also be affected. Hermione could be intrigued by the scientific side of Harry's heritage and try to study it, while Ron might be a bit more wary at first.

I really liked a fanfic where fem Harry Potter accidentally travels to Bruce Banner's world. It shows how she tries to adapt to this new world full of science and technology, which is so different from the magical world she's used to. And Bruce Banner is intrigued by her magic. It's a great exploration of two very different characters coming together.
