Perhaps they reunite in a forest where there's a rare Pokémon sighting. They both remember their adventures together and how they used to face challenges. They might start reminiscing about the times they got lost in similar forests before. Then, they could join forces to catch the rare Pokémon. Ash would use his battle skills, and Dawn would use her knowledge of Pokémon behavior to come up with a plan.
It could also have an emotional impact on the Pokémon. Some of the Pokémon might have felt lonely without their old friends. When they reunite, they would feel a warm sense of belonging again. This could improve their overall well - being and performance. The Pokémon might even start behaving more playfully and be more energetic, as they are now in a more positive and familiar environment with their friends.
Ash is a well - known Pokémon trainer, always eager to catch new Pokémon and battle strong opponents. He has a kind heart and is very passionate about Pokémon. Dawn is another trainer, who is often shown to be determined and has her own unique style of training. In the 'dawn confesses to ash fanfiction', their relationship takes a turn towards the romantic as Dawn decides to be honest about her feelings for Ash.
Some potential rivals could be the local Unova trainers who are known for their unique battling styles. For example, a trainer who specializes in using Bug - type Pokemon could be a tough rival for them.
They might have an epic battle against a common enemy together. Greninja could show off some new moves it has learned during their separation, and Ash could use his experience from other adventures to lead them to victory.
One great 'Ash and Dawn Fanfiction' is 'A New Journey Together'. It beautifully portrays their adventures beyond the anime. It has a well - developed plot that focuses on their growth as trainers and also their relationship development.
One idea could be that Ash and Dawn visit Paldea for a special Pokemon exchange event. They meet new Pokemon and trainers, and Ash gets into some friendly battles with the local champions. Dawn, on the other hand, discovers new forms of Pokemon contests in Paldea and decides to participate.
I would recommend 'The Pokémon Partners'. In this fanfiction, Ash and Dawn form an even stronger partnership. They learn new techniques together and it's really cool to see their relationship develop. It has some really creative battle scenes too.
Their reunion could be filled with a rush of old memories. Maybe Ash would show Misty all the new Pokémon he's caught. And Misty would tell Ash about her adventures back at the gym. They might even decide to travel together again for a while.
