Your OC could be a time - traveler who goes back in time to prevent the accident that created the Hulk. This would completely change the Avengers' timeline and create a complex web of events. Banner would have to deal with this new reality where he may not be the Hulk, and the OC would have to face the consequences of meddling with time. There would be a lot of moral and ethical dilemmas, as well as action - packed scenes as the Avengers try to stop or help the OC's mission.
A plot idea could be that the OC is an alien who crash - lands near Bruce Banner's lab. The OC has some sort of technology that can either help or hinder Banner's control over the Hulk. This would create a lot of mystery and a race against time as the Avengers try to figure out the OC's intentions and how to deal with this new factor.
One idea could be that your OC is a therapist hired by the Avengers to help Bruce Banner deal with his psychological issues related to the Hulk. This would involve deep emotional conversations between the two characters and a new perspective on Banner's struggle.
In fanfiction, Bruce is often portrayed as the brains behind many of the Avengers' strategies. His scientific knowledge is invaluable. At the same time, his struggle with the Hulk can be a source of both drama and humor. For instance, there might be scenes where he accidentally turns into the Hulk at the wrong moment, creating chaos but also a chance for him to show his strength.
First, focus on creating a unique Original Character (OC). For a Bruce Banner - related fanfiction in the Avengers universe, understand Banner's character traits. He's intelligent but struggles with the Hulk inside him. Your OC could be a scientist too, and have an interesting dynamic with Banner, like being a rival who later becomes an ally. Maybe they meet in a research facility and initially clash over different scientific theories. This can create great tension and plot development.
One common theme is his struggle with the Hulk. Writers often explore how he copes with this dual identity, like in stories where he tries to find a permanent cure. Another theme is his relationships, especially his friendship with the other Avengers. For example, how Tony Stark might help him with his scientific research related to the Hulk.
Bruce Banner in Avengers fanfiction is often depicted as a complex character. He's not just the Hulk, but a brilliant scientist. Writers usually explore his internal struggle between his human self and the Hulk. His relationships with other Avengers, like Tony Stark, are also interesting. They can be friends, but also have scientific rivalries.
Perhaps in a fanfiction, Bruce Banner discovers a new form of science that can enhance Thor's powers even more. Thor, in turn, helps Bruce understand the Asgardian view of the universe, which gives Bruce new insights into his own work. This could lead to a series of events where they team up against a common enemy that is a threat to both Earth and Asgard.
Another plot could be that Bruce Banner is doing some research on a new form of energy and it somehow links to Harry's magic. Harry is brought in to help understand this strange new energy which has properties similar to magic. In the process, they learn from each other's worlds and develop a friendship while trying to keep this discovery from falling into the wrong hands.
Sure. One great piece is 'The Green Genius: A Bruce Banner OC Adventure'. It features an original character who becomes an assistant to Bruce Banner in his scientific research. The story delves into their relationship and how they work together to overcome various challenges.
Redemption is a theme that pops up as well. Some fanfictions might focus on Bruce Banner trying to make up for the destruction The Hulk has caused in the past. He could be on a mission to save the world in a more controlled and positive way, to prove that he's more than just a potential danger. There are also stories that deal with his acceptance by society, as many people in the Marvel universe might be afraid of The Hulk. These stories show how he tries to change that perception.
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.
One plot idea could be Percy and Bruce Banner teaming up to fight a new type of monster that is affected by both magic and gamma radiation. Another could be Percy getting lost in a scientific research facility where Bruce works and they have to figure out how to get Percy back to his world while also dealing with some lab - created threats. Maybe they also discover that there is a connection between the Greek gods and the science behind the Hulk.
