Many fanfictions explore her training methods. Since she has two very experienced Pokemon trainers as parents, she might develop her own innovative training techniques. This could be something that sets her apart from other trainers in the fanfiction world. For example, she could combine Ash's hands - on approach with Dawn's more strategic methods.
One common plot could be that Ash is betrayed by a so - called friend in the Pokémon world who teams up with a rival trainer to undermine his journey. Maybe this friend spreads false rumors about Ash's training methods. Another plot might involve Dawn being betrayed by a coordinator she trusted. This person could steal her unique Pokémon training techniques and use them for their own gain. There could also be a plot where both Ash and Dawn are betrayed together by a powerful Pokémon organization that wants to stop their progress in the Pokémon world.
One common theme is growth. They both grow as Pokémon trainers and as people, and that growth brings them closer together. For example, they might learn new training techniques from each other which deepens their respect and admiration.
Another plot is that Ash dresses as a girl as part of a bet or a challenge. Throughout the fanfiction, he discovers new aspects of himself or the Pokemon world that he wouldn't have otherwise. For example, he might learn about the unique challenges female trainers face.
In Pokemon fanfiction, the idea of Ash and Dawn having a daughter can lead to many interesting storylines. It could involve their daughter inheriting their love for Pokemon battles. Maybe she'd start her own journey, with Pikachu or one of Dawn's Pokemon as her partner.
One common plot is that Ash discovers a hidden egg of a legendary starter Pokémon. He then has to protect it from poachers or other trainers who want to use its power for evil. Another plot is when Ash is chosen by a legendary starter Pokémon to be its partner to save the Pokémon world from a great threat.
One common plot could be Bella having some sort of latent magical ability inherited from Bellatrix. For example, she might be able to perform dark magic in the 'Twilight' world which would be a huge shock to the vampires and werewolves. Another plot could be that Bellatrix hid Bella in the 'Twilight' world for some reason, like to protect her from the other dark wizards in the 'Harry Potter' universe. And then there could be a plot where Bella discovers her true heritage and has to deal with the consequences, like trying to balance her 'Twilight' life with her new - found connection to the wizarding world.
One common plot is that Ash gets betrayed by someone he trusts deeply, which causes him to turn evil. For example, if the Pokemon League rejects him unfairly. Another plot could be that he gets influenced by a powerful, evil Pokemon or a dark force. He might then start to use his Pokemon in cruel battles, not caring about their well - being.
There are fanfictions where Ash and Dawn participate in Unova's Pokémon contests. Dawn, with her contest experience, could teach Ash some new tricks. They could enter as a duo and create unique performances using Unova's Pokémon. In some fanfictions, they also meet old friends from other regions in Unova, which leads to a lot of fun interactions and reminiscing about their previous adventures.
One popular Ash and Dawn Sinnoh fanfiction could be those that focus on their journey through the Sinnoh region, with new adventures not shown in the original series. For example, a fanfiction might have them encounter a rare and powerful Pokemon that changes the course of their journey.
One reason is the chemistry that can be created between them in fanfictions. In the original series, they have a certain dynamic that can be easily turned into a romantic one. Also, fans are always curious about 'what if' scenarios. What if Ash and Dawn fell in love? A kissing scene is a big part of that exploration. It adds a new dimension to their relationship that the anime might not have fully explored.
