One interesting idea could be May's return with a new and powerful Pokémon team. Maybe she has been on a secret training journey and comes back to surprise everyone in a big Pokémon battle tournament.
Another character she could interact with is Max, her younger brother. Their reunion would be quite emotional. Max might have grown as a Pokémon trainer himself, and they could exchange tips and experiences, or even embark on a new adventure together.
There might be a fanfiction where May returns to compete in a special Kalos tournament. She has to face tough opponents and also deal with some personal growth along the way. For example, she could learn new battle strategies and form new friendships. This type of story would show her development as a trainer since we last saw her in the Pokemon XY series.
You can try fanfiction websites like Archive of Our Own (AO3). It has a large collection of Pokemon fanfictions, and you're likely to find some great ones about May's return in the XY series there.
A possible fanfiction plot could be that Ash, Serena, and May are invited to a mysterious island full of unknown Pokemon. They have to work together to survive and discover the secrets of the island. Ash's leadership, Serena's ability to communicate with Pokemon, and May's quick decision - making skills would be crucial.
Well, it's completely inappropriate. Pokémon has always been about positive values like friendship, adventure, and growth. Creating fanfiction with such inappropriate themes as 'naked pokemon' not only distorts the original concept but also might be offensive to a large number of fans who enjoy the series for its intended charm and wholesomeness.
In some cases, there could be a new antagonist in the fanfiction. This character could be a powerful trainer or a villainous Pokemon that stands in the way of Charizard and its trainer. Their presence creates conflict and drives the story forward as Charizard and the trainer must overcome them.
One common theme could be redemption. Maybe Ash has to make up for something from his past. Another theme might be reunion, like reuniting with lost friends or family.
I'm sorry, I don't have specific fanfictions to recommend right away. But you can try looking on fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Pokemon May' and browse through the results to find ones that might be similar in theme or style.
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.
