One key element is the contrast between their characters. Bruce is often seen as a meek and brilliant scientist, while Loki is a cunning and powerful god. Their interactions based on this contrast can create interesting storylines.
Loki may also kidnap Bruce Banner as a way to get at the Avengers. Since Banner is an important part of the team, taking him hostage could be a strategic move to draw out the other Avengers and then manipulate or defeat them. It could be part of a bigger scheme to gain power or control over Earth or the universe.
One popular Bruce Banner Loki fanfic is 'A Strange Alliance' which explores an unexpected friendship between them in the face of a common enemy. It delves into their different personalities, with Bruce's scientific mind and Loki's mischievous nature creating an interesting dynamic.
At first, Bruce might be scared. He knows Loki's reputation for being unpredictable and dangerous. But he also tries to keep his cool because he doesn't want to accidentally transform into the Hulk right away. He might try to reason with Loki, using his intelligence to talk his way out of the situation.
Bruce Banner fanfic, when not involving inappropriate content, usually has a strong focus on his internal conflict. He is a man of science who has been burdened with this uncontrollable alter - ego. Fanfics can show his attempts to find a cure or at least better manage the Hulk. In addition, his relationships within the Avengers can be a central aspect, whether it's his mentorship of Peter Parker or his camaraderie with Steve Rogers.
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.
One idea could be a story where Bruce and Natasha are on a mission together in a remote location. They have to rely on each other's skills to survive. Bruce uses his scientific knowledge to figure out a way to stop a dangerous experiment gone wrong while Natasha uses her combat skills to protect them from the threats around. Their relationship gradually deepens as they face challenges side by side.
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.
In a 'bruce banner death fanfic', it could be that Banner is tricked by a powerful villain into believing that his continued existence is a threat to all of humanity. Depressed and believing he has no other option, he takes his own life. This could lead to a complex exploration of the ethics of superheroes and the power they hold, as well as the impact of Banner's death on his friends and the world at large.
No. Most fanfics in the superhero genre tend to focus on heroic deeds, character relationships, or alternate universes where the heroes are even more powerful or face different challenges. Stories about a character like Bruce Banner committing suicide are quite rare as they are very dark and go against the typical heroic image associated with superheroes.
