One idea could be that Ash discovers a hidden power within himself related to water types. Maybe he has a special connection with a rare water - type Pokemon that helps him unlock this new ability. For example, he meets a mythical water - type Pokemon in a hidden cave. The Pokemon sees Ash's pure heart and decides to bond with him, allowing him to control water in ways he never thought possible.
In fanfiction, Ash might discover a special water - type stone that enhances his bond with his water - type Pokemon. This stone could have the power to boost their abilities and his own understanding of them. With this new advantage, he enters water - type Pokemon tournaments and gradually builds his reputation as a water master. He also shares his experiences with his friends, who support him in his journey.
There are fanfics where Ash gets transported to a parallel universe where water Pokemon are the dominant species. He has to learn the ways of this new world and befriend water Pokemon to survive. Some fanfics also focus on Ash training his water Pokemon in unique ways, perhaps using the power of the ocean currents to enhance their strength. These fanfics often explore different aspects of the Pokemon world and Ash's character in relation to water Pokemon.
When writing your 'Ash Water Pokemon Fanfic', begin by deciding on the theme. If it's about Ash and his journey with water Pokemon, think about how he will interact with them. Will he learn new training techniques? Then, develop the characters. Ash should be his brave and determined self. For the water Pokemon, give them distinct personalities. As for the plot, it could involve Ash entering a water - themed Pokemon competition. Along the way, he makes new friends and overcomes obstacles. Write in a way that captures the essence of the Pokemon world and the charm of Ash's character.
Pikachu is a very likely candidate. It's Ash's most iconic Pokemon and has a deep bond with him. Whenever Ash is in trouble, Pikachu often steps up to protect him.
Ash could be a Pokémon trainer with a different starting point in this fanfiction. Born in 1987, by 1997 he might have already made a name for himself in local Pokémon battles. He could have a team of Pokémon that he rescued from difficult situations, like a Charmander that was abandoned by its trainer. His story could revolve around giving these Pokémon a second chance and proving that Pokémon don't need to be 'perfect' to be strong.
The impact of Ash's loss in the fanfiction could extend beyond just himself. His Pokémon might also feel demoralized. However, this could also be an opportunity for them to grow stronger together. Ash could start training more intensively, seek new training methods, or even try to catch new Pokémon to strengthen his team.
For Ash, Pikachu is always a great choice as it's his most loyal and powerful partner. Alongside that, a strong flying type like Charizard could be useful. For Brock, his Onix would be a staple. And perhaps a water - type like Vaporeon could be good for him to balance his team. Since they are teaming up, having a psychic - type like Alakazam could also be beneficial as it can help in battles and also with communication in tricky situations.
Ash could also have Charizard. It's a powerful and well - loved Pokemon of his. It could provide a lot of firepower in battles. For Gray, a Glaceon would be great. Glaceon's ice - type moves could complement Gray's more strategic style. It could freeze opponents and give Gray time to plan his next move.
If we consider the common growth pattern in the Pokemon series, Charmander evolving into Charmeleon could be an early evolution in the fanfiction. Since Charmander has a clear evolution line and Ash has a strong bond with it, it would make sense for it to be one of the first to evolve, perhaps due to a tough battle or a special encounter that accelerates its growth.
