Well, clearly the main characters are May and Ash. May is a Pokémon coordinator, and Ash is a Pokémon trainer. Their different skills and personalities make their interactions in the fanfiction really interesting.
One interesting plot could be May and Ash going on a special adventure together in a region they haven't explored before. They might encounter rare Pokémon and have to work as a team to overcome various challenges.
Obviously, Ash himself. And his Kalos friends like Serena would probably be there. Clemont and Bonnie might also make an appearance as they were important parts of Ash's Kalos journey.
Well, one possibility is that Ash continues his Pokemon training in Kalos, facing new and stronger opponents. Maybe he teams up with old friends from Kalos to take on a new threat to the region.
One possible fanfiction could be about Ash's adventures in Hoenn during the month of May. Maybe he discovers a new Pokémon species that is only active during this time of the year. He could be traveling with his usual companions and facing challenges specific to the Hoenn region.
It could be a rival trainer. Rival trainers are often very competitive in the Pokémon world. Maybe this rival is jealous of Ash and May's progress and decides to betray them to slow them down. They might spread false rumors about Ash and May, causing other trainers to be distrustful of them.
One way is to focus on their friendship. For example, write about how they support each other during Pokémon battles. They can exchange tips on training Pokémon or strategies for winning competitions.
Often, these fanfictions will take the characters out of their normal settings. For example, they might end up in a different time period or a strange new land. This allows for a lot of creativity in the storylines. And the character development of May and Ash is usually a big part of it, showing how they grow and change throughout the story.
Yes, there might be. Fanfiction covers a wide range of scenarios and relationships, so it's possible that someone has written a story where May cheats on Ash. You can try searching on popular fanfiction websites.
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.
