There are several common themes. Firstly, there's the theme of redemption. Mysterio is often a villain in the original story, and in gay fanfics, his relationship with Spiderman can be a path to redemption. Secondly, the theme of trust is big. Given their complex relationship in the original material, building trust in a romantic relationship in the fanfic is crucial. And thirdly, the theme of discovery. They are both discovering new sides of themselves and each other in the context of a gay relationship, which can be an interesting exploration of their characters that you don't see in the traditional storylines.
One common theme is the struggle with identity. Since they are both characters with complex identities in the original stories, in the gay fanfics, they might struggle with their new relationship and how it fits into their existing identities. Another could be the idea of secrecy, as in the original stories they both have secrets, and in a gay relationship in the fanfic world, they may have to keep their relationship a secret too.
One common theme is the exploration of their age difference in a romantic context. Another could be how they support each other in different ways compared to the traditional superhero relationships. Also, the idea of mentorship turning into something more is often explored.
One possible plot is that Mysterio has a change of heart. He decides to use his skills for good and teams up with Spiderman to take on a new super - villain in the city.
A fanfic might explore Mysterio's illusions in relation to Spiderman. For example, Mysterio could use his illusions to help Spiderman train for tougher battles by creating realistic combat scenarios. It could also delve into their psychological relationship, like how Spiderman tries to understand Mysterio's motives despite his villainous nature.
Common themes often include them teaming up in unique ways that lead to a deeper emotional connection. For example, they might go on a mission together that forces them to rely on each other more than usual, and this could be the start of a relationship in the fanfic. Also, themes of mutual respect and admiration are frequently explored, as they are both heroes with different but equally valuable skills and qualities. Another aspect could be the exploration of how they deal with the public's perception of their relationship if it was more than just a friendship in the fanfic world.
Conflict and resolution is a major theme too. There's usually initial conflict between Tony and Mysterio due to their different motives and personalities. But as the story progresses, they find ways to resolve their differences, whether it's through mutual understanding, a common enemy, or a shared goal. This theme keeps the readers engaged as they watch the relationship between the two characters evolve.
One common theme is the idea of Spiderman being the center of attention for multiple characters. It often involves themes of love and attraction. For example, different female characters may be drawn to his heroic nature.
A common theme is also the idea of support. MJ being there for Peter during his superhero battles, and Peter relying on MJ's strength and understanding. And of course, the theme of adventure. Sometimes MJ gets dragged into Peter's adventures as Spiderman, and how they face those together.
A common theme is the battle between good and evil. Spiderman represents good and Carnage represents pure evil. Another theme is the struggle for power. Carnage is always seeking more power and Spiderman has to stop him. And of course, the theme of heroism. Spiderman has to be heroic in the face of Carnage's atrocities.
One common theme is the struggle with identity. Both characters have complex identities in the original lore, and in gay fanfiction, this can be intertwined with their sexual identities. Another is the idea of an unlikely bond. They are often enemies in the original stories, so exploring how they come together in a romantic way is popular.
Another theme is the idea of heroism. Both Overwatch and Spiderman are about heroes, and in these fanfics, they usually combine their heroics. For example, they might fight a common enemy that neither could defeat alone. It shows that different types of heroes can work together for the greater good.
