Maybe Tracey. He was also an acquaintance of Ash. Since Tracey has his own unique skills and knowledge about Pokemon, his presence could bring new elements to the story. He could help Ash and other friends with things like Pokemon research or understanding some rare Pokemon behaviors.
One possible reason could be jealousy. Maybe Ash has achieved more in his Pokemon journey than his friends, and they can't handle it. Another reason might be some misunderstanding. For example, an enemy could trick Ash's friends into thinking Ash has done something bad. Or perhaps there's some sort of power struggle. If there's a powerful item or a rare Pokemon involved, and Ash is the main contender, his friends might be tempted to betray him for their own gain.
Well, their friends could also play a role in bringing them together for the kiss. For example, they might set up a special date - like - like a picnic or something. And when the kiss finally happens, their friends would be overjoyed, cheering and maybe even planning a celebration for the new couple.
He could make friends with Dawn. She's a well - known character in Sinnoh and her knowledge of Pokémon contests could be really helpful to Ash. Another potential friend could be Barry. His energetic and competitive nature would make for some interesting interactions with Ash.
Ash would probably be devastated. He would feel like his world has been turned upside down. At first, he might not believe it and think it's all a big mistake. As the reality sinks in, he could start to isolate himself from others, even from his Pokemon for a while. However, his strong will would eventually kick in. He would use this as motivation to become stronger, not just in his Pokemon battles but also in his ability to face challenges alone, without relying on his so - called friends.
One possible plot could be Ash feeling lonely and deciding to go on a solo journey to prove himself. He faces various challenges alone and in the process discovers his own inner strength. He might encounter some Pokémon that become his temporary companions during battles but then part ways, emphasizing his solitude.
His friends might be really confused at first. Pikachu, for example, might give Ash some really puzzled looks. If Ash tries to explain to his friends that they're all part of a fanfiction, some of them might not believe him at all. Misty could think Ash has hit his head or something and is just spouting nonsense.
His friends would likely have a mix of reactions. Some, like Pikachu, would be right by his side and excited for the new adventure. Others, like his human friends, might be a bit sad at first because he'd be spending more time with the Elite Four duties. But overall, they'd be proud of him. They know how hard he's worked to get to this point in his Pokémon training journey. And they'd also be looking forward to seeing how he'd change the Elite Four with his unique style.
