The exploration of different realms and dimensions is also common. Since both 'Supernatural' and 'Marvel' have multiple universes and otherworldly places, fanfictions often take characters on adventures through these realms. It could be the Avengers traveling to a dimension full of demons from 'Supernatural', which makes for some exciting and unique storylines.
One common theme is power. Since Maelstrom has such unique powers, a lot of fanfictions explore how he uses or misuses them. For example, some stories focus on his attempts to gain more power and the consequences.
One common theme is empowerment. Female characters often face challenges and rise above them, like Black Widow dealing with her past and becoming stronger. Another theme is friendship. For example, the X - Men female characters supporting each other. And there's also the theme of self - discovery, as seen in stories about Ms. Marvel finding out who she really is as a superhero.
One common theme is the exploration of relationships. Since it's a harem concept, there's a focus on how the main character interacts with multiple love interests. Another theme is power dynamics. For example, in a fanfiction where a superhero has a harem, it might show how their powers affect their relationships.
Since I don't encourage or promote 'lemons' fanfiction (due to its often inappropriate nature), I can't accurately list common themes. However, in general Marvel fanfiction often has themes of heroism, redemption, and the power of friendship. These are positive and more acceptable themes that are widely explored in non - inappropriate fanfiction.
In 'supernatural fanfiction', a frequent theme is the alternate universes. Writers like to imagine different versions of the 'Supernatural' world, where things happened differently. Romance is also a big theme, whether it's between the main characters or new characters introduced in the fanfic. Also, the origin stories of the supernatural beings are often explored, giving more background and depth to the existing lore.
One common theme is the combination of powers. Since it's a crossover of two power - based universes, stories often explore how Marvel powers and My Hero Academia quirks can work together or against each other.
In these fanfictions, a frequent theme is adaptation. The Flash has to adapt to the Marvel universe, and vice versa for the Marvel characters. They need to figure out how to work together or against each other. Friendship is also a theme. Despite their differences, characters from both universes might form unexpected friendships. For instance, the Flash could become friends with Spider - Man due to their similar senses of humor and youthfulness.
Another theme is friendship and alliances. The male OC usually forms bonds with the well - known Marvel characters. He might start as an outsider but then become friends with characters like Captain America or Thor. These friendships are important for his development and also for the plot as they team up to face common enemies.
Well, one common theme is the power struggle. In both Naruto and Marvel, characters have unique powers. So in fanfiction, it often explores how these powers interact when the universes collide. For instance, Naruto's Rasengan vs. Iron Man's repulsor beams.
One common theme could be romantic or sexual relationships between Marvel characters. For example, a relationship between two superheroes that is explored in a more 'lemon' - like way, which might include more physical and emotional intimacy than in the official comics. But again, this is often not in line with the mainstream Marvel universe.
