Yes, there might be. The Pokemon fandom is vast, and various fan - created stories exist. Some fans might come up with a plot where May is kidnapped as a way to create drama and drive the story forward. However, it may not be a very common or mainstream type of fanfic.
The plot could start with May being kidnapped by a mysterious figure who is actually an old acquaintance from her past who has turned bad. This person blames May for something that happened long ago and wants revenge. Meanwhile, May has to use her wits and the bond she has with her Pokemon to try and escape on her own. At the same time, her friends are on her trail, facing various obstacles and battles as they search for her. As the story progresses, secrets from May's past are revealed, and it all builds up to a big showdown between May's rescuers and her kidnapper.
Well, 'pokemon may kidnapped fanfiction' could potentially center around the idea of May getting abducted in a scenario that the fanfiction writer has dreamed up. It could be part of a larger plot where the kidnapper has some devious motives related to Pokemon - perhaps they want to use May to get to a powerful Pokemon she has a connection with. It's all speculation without actually reading the fanfic.
It's hard to say. There are so many fanfictions out there that it's difficult to determine which ones are popular. The 'pokemon may kidnapped fanfiction' might be popular within a small group of Pokemon fans who are interested in that particular type of story, but it may not have made it to the mainstream of fanfiction popularity.
Another option is a random criminal who just sees May as an easy target. He might not even be related to the Pokemon world initially but realizes that he can ransom her to her wealthy Pokemon - loving family or friends. However, he soon finds out that dealing with a Pokemon trainer's friends is not as easy as he thought.
Well, it could be about a villainous team kidnapping a rare Pokemon. For example, Team Rocket might target a shiny Pikachu. They'd use various devious means like traps or distractions in the Pokemon world to capture it. Then, the trainer of the Pikachu would have to embark on a dangerous journey to rescue it, facing many challenges along the way.
Well, one possibility is that her friends would immediately start a search party. They might split up to cover more ground, with some going to the forests where they often find Pokemon and others checking out the local towns. Her Pokemon would also be in a frenzy, trying to use their unique abilities to track her down.
A 'pokemon lemon may fanfic' could be a fan - created story about Pokemon that involves a character named May and might have some romantic or unorthodox plot elements. But it's hard to be more specific without reading it.
I haven't actually read this 'pokemon may and norman lemon fanfic' in detail. But generally, in Pokemon fanfics, the relationship between May and Norman can be explored in very interesting ways. It might show May's growth as a trainer under Norman's guidance, or perhaps some unique adventures they have together that are different from the main Pokemon storylines.
