One possible plot could be that Ash and May are on a journey through a forest. They encounter Plusle and Minun who are in trouble because a group of wild Pokémon are chasing them. Ash and May decide to help. They battle the wild Pokémon together, with Plusle and Minun using their electric moves to assist Ash's Pokémon and May's Pokémon. Afterward, Plusle and Minun become friends with Ash and May and join them on their journey for a while, leading to various adventures like exploring ancient ruins and solving mysteries in the Pokémon world.
One possible plot could be that Ash and May are exploring a new region. They come across a forest where they notice Plusle and Minun playing. They decide to try and catch them. Ash uses Pikachu to try and weaken Plusle while May uses her Skitty to do the same to Minun. After a bit of a chase and some battles, they manage to catch them. Then they discover that Plusle and Minun have a special ability that can help them in their future adventures.
One idea could be that Ash and May find a pair of Plusle and Minun that are lost. They then embark on a journey to reunite them with their family. Along the way, they face challenges like wild Pokémon attacks and difficult terrains.
Ash's boldness would likely contrast with May's more refined approach. Plusle and Minun's playfulness would add a light - hearted touch. Ash might get Plusle and Minun into some wild adventures, while May would try to keep them in line when it comes to her contest - related activities. Plusle and Minun could bring out the fun - loving side of both Ash and May. For example, they might convince Ash to take a break from his intense training and have a little fun, and they could also make May see the value in just enjoying the moment with Pokémon outside of contests.
For Ash, his already existing determination can be further emphasized when it comes to protecting Plusle and Minun. He could show more patience in teaching them new things. May could become more confident in her decision - making. Maybe she takes the lead in some situations involving Plusle and Minun. For Plusle and Minun, their playfulness can be a starting point. As the story progresses, Plusle could become more cautious while Minun could grow to be bolder.
Their relationship with other Pokémon would likely change quite a bit. For Ash, his other Pokémon like Charizard might initially be a bit aloof towards Plusle and Minun. But as they see how useful Plusle and Minun can be in battles and how they contribute to the team spirit, they would warm up to them. For May, her Pokémon like Eevee could start to develop new strategies in battles with the addition of Plusle and Minun. Plusle and Minun's presence could also encourage Ash and May's other Pokémon to be more social, as they are very social Pokémon themselves. This could lead to more group activities among all of Ash and May's Pokémon, like playing games together or exploring new areas as a united group.
One possible plot could be a reunion story. Ash has been traveling far and wide for his Pokémon journey. May, on the other hand, has been focusing on her own career in Pokémon contests. They accidentally meet at a Pokémon event. Old feelings start to resurface, and they realize that they still have a deep connection. Eventually, they decide to get married. Their Pokémon also play a big role in the story, like Pikachu helping Ash to plan a surprise for May with the other Pokémon.
Perhaps May betrays Ash because she's influenced by a new group of trainers. They might convince her that Ash's way of training Pokémon is wrong or that he's holding her back from achieving greater things. So, she sides with them against Ash. This would show how easily friendships can be tested in the competitive world of Pokémon training.
In the fanfiction, Ash and May could get married in a secret location, away from the public eye. They've had a long - standing relationship that they've kept private. The story could revolve around their journey to this secret location, with only their most trusted Pokemon by their side. Along the way, they reminisce about all their adventures together and how they fell in love. Once they reach the location, it's a simple yet intimate wedding with just a few close friends and their Pokemon.
Maybe in a story, May gets injured while protecting Ash from a powerful Pokemon. Ash, feeling extremely grateful and realizing his deep - seated affection for her, kisses her. Then the plot could develop as they deal with the newfound feelings and how it affects their Pokemon - training journey.
They could start with Ash and May reuniting at a big Pokémon event. They start spending more time together, reminiscing about their old adventures. Their relationship blossoms, and then May becomes pregnant. The story could then focus on how they adapt to this new situation, with Ash trying to balance his Pokémon training with being a soon - to - be - father and May preparing for motherhood while still having her own Pokémon - related goals.
