The uniqueness lies in the potential character development. When either Ash or Paul is sick, it gives the author a chance to explore their more vulnerable sides. For example, a sick Paul might show a side of him that's less competitive and more in need of friendship, which is a new aspect of his character.
One good example could be a fanfiction where Ash gets sick during a big Pokemon battle against Paul. In this story, his Pokemon have to step up and fight even harder to make up for his weakened state. Maybe Pikachu takes on a leadership role among the team.
The allure might lie in the fact that Ash and Paul have a complex relationship in the original series. A lemon fanfiction could heighten that complexity in a more adult - themed way. But again, it may not be everyone's cup of tea.
When it comes to Pokemon Ash and Paul lemon fanfiction, it can be a way for fans to explore their own ideas about the characters. For example, it could show a situation where their rivalry turns into something more passionate. However, these types of fanfictions are not always in line with the official Pokemon storylines and might have content that some people find inappropriate.
Obviously, Paul himself is the central character. His brother Reggie might also appear as he could be concerned about Paul's condition and offer support. Ash could be in it too. He might be someone who initially doesn't get along with Paul but then shows compassion because of his illness. And of course, Paul's Pokemon would be there, like his Torterra or Electivire.
One popular theme could be Paul's struggle with his illness while still trying to pursue his Pokemon training goals. It might show his determination in the face of physical challenges. Another theme could be the relationships he forms with his Pokemon during this tough time. His Pokemon might become more protective or show extraordinary loyalty.
The theme of friendship also emerges in some cases. Despite their rivalry, there are moments when they show respect for each other or even help each other out in difficult situations. This shows that beneath their competitive exterior, there is a potential for a deeper connection.
Some fanfictions focus on their rivalry evolving into friendship. Paul starts off as quite antagonistic towards Ash, but over time, through shared experiences like traveling in the same region or helping each other out in a Pokémon - related crisis, they begin to respect and even like each other. For example, in a story, they might both get lost in a dangerous forest and have to rely on each other's Pokémon skills to get out, which changes their relationship for the better.
The Pokemon themselves can also be considered important characters in a way. They are not just companions but also a big part of the world. Their battles and interactions can mirror or influence the relationship between Ash and Paul. For example, if Paul's Chimchar evolves during a battle against one of Ash's Pokemon, it could be a turning point in their relationship.
I haven't read this specific fanfiction, so I can't summarize it directly. But generally, it might involve Paul taking some heroic actions to save Ash in the Pokemon world. Maybe Paul overcomes some challenges or battles against powerful opponents to rescue Ash from a dangerous situation.
