One common trope could be the power struggle between the possessor and the possessed. Another might be the exploration of new identities and how it affects relationships in the fanfic world.
Sure. There are often fanfics that take a more innocent approach to body possession in the Pokémon world. These might be centered around friendship and cooperation between the Pokémon and the trainer. They could involve scenarios like a Pokémon temporarily taking over a trainer's body to protect them from danger in a non - sexual, heroic way.
There's also the matter of how the body possession is depicted. If it involves violating Hermione's privacy or using her body in inappropriate ways, it crosses ethical boundaries. Fanfic writers should be careful to create a story that is engaging without being unethical towards the character.
Another body swap idea could involve a scientific experiment gone wrong. Chris Hemsworth's character volunteers for an experiment that accidentally swaps his body with another person. They both have to navigate each other's lives, with Hemsworth's character having to deal with things like the other person's job, relationships, and daily routines, which is quite a challenge.
One popular body possession fanfic could be those in the superhero genre where a villain possesses the body of a hero to cause chaos. Another might be in a fantasy setting where a dark spirit takes over a wizard's body.
I'm not really into that specific genre. But generally, a good body possession story in fanfic might involve a character suddenly finding themselves in another's body and having to navigate the new situation. It could lead to some unique character development and interesting plot twists.
First, create interesting characters. The possessor should have a distinct personality. Then, build a solid plot around the possession. Maybe start with the moment of possession as a hook.
