Well, in some ash and bonnie body swap fanfiction, there could be a plot where Ash in Bonnie's body discovers a hidden talent that Bonnie had but was too shy to show. Maybe it's a talent for singing or drawing. On the other hand, Bonnie in Ash's body could face challenges in the Pokémon world that she never expected, like dealing with a very difficult Gym Leader. Also, they might have to keep their body swap a secret from most people to avoid chaos, which adds an element of mystery and suspense to the story.
One interesting plot could be that Ash, now in Bonnie's body, has to deal with the different social interactions that Bonnie usually has. For example, he might struggle to interact with Bonnie's friends in the way she does. Another plot could be Bonnie, in Ash's body, trying to handle Ash's Pokémon battles. She might use different strategies that surprise everyone. And a third plot could be them trying to find a way to swap back while also learning more about each other's lives.
One interesting plot could be that Ash, now in May's body, tries to enter a Pokemon Contest. He has to quickly learn the skills and grace that May has, like how to style the Pokemon in a more appealing way for the judges. Meanwhile, May in Ash's body decides to enter a Gym battle. She struggles with Ash's more straightforward and battle - focused approach compared to her Contest strategies.
One interesting plot could be Superman swapping bodies with a normal human. The human then has to deal with Superman's powers while Superman experiences what it's like to be an ordinary person. He might struggle with things like paying bills or getting to work on time in the human's body.
Ash is typically a very determined and adventurous character. So when he's in Bonnie's body, he might bring that sense of adventure into Bonnie's more ordinary daily life. For example, he could be more eager to explore new places around the town. Bonnie, on the other hand, is often curious and energetic. In Ash's body, she'd probably show a lot of enthusiasm for Pokémon battles and training, perhaps approaching it with a fresh perspective that Ash himself might not have considered before.
Well, perhaps there's a plot where the body swap is part of a villain's plan.

They have to adapt to each other's powers and relationships. For example, if she swapped with Captain America, she'd have to deal with his leadership role and he'd have to handle her stealthy and more morally ambiguous world.
Another plot could be that the body swap was caused by a strange jutsu gone wrong. In the process of trying to fix it, they end up learning more about each other. Naruto could understand Ino's insecurities better, and Ino could see Naruto's determination and the weight of his responsibilities more clearly. This new - found understanding could change their relationship for the better even after they swap back.
A plot could involve them trying to reverse the body swap. They might search through the library, looking for ancient spells or potions that could fix their situation.
