One possible plot could be that Ash is on a journey and meets a unique female Pokémon trainer. This trainer has a special bond with a rare female Pokémon. They team up to enter a Pokémon competition that is only for female trainers and their Pokémon. Along the way, they face challenges from other trainers who underestimate them. Ash, with his experience, helps the female trainer strategize and they both learn from each other about different Pokémon types and how to train them better.
Well, it could be about Ash getting some really special and secret training from Professor Oak. Maybe Oak teaches him some unique battle strategies that no one else knows. This could lead Ash to become an even more formidable trainer in the Pokemon world.
Another option could be Dawn. She has a passion for Pokémon contests. The fanfic could be about her journey to train a particularly difficult - to - train female Pokémon for a major contest. Ash asks Professor Oak about her progress, and Oak tells him some interesting stories about Dawn's training methods and the bond she's forming with the Pokémon.
The main characters are obviously Ash and Professor Oak. Ash is the young and enthusiastic Pokemon trainer, and Professor Oak is the wise and experienced Pokemon expert.
One possible reason could be that in the fanfiction, Ash might be depicted in a way that goes against Professor Oak's character values. For example, if Ash is shown as disrespectful to the Pokémon world's traditions which Professor Oak holds dear.
Another possible main character could be Gary. Since Gary has a connection to both Ash and Professor Oak, he could play a role. Maybe he's jealous of Ash getting special training from Oak and tries to interfere or he could also be inspired by Ash's training and start his own journey of improvement. Also, Misty or Brock could be involved as they are Ash's friends and might visit during the training to see how he's doing.
The fanfiction might also focus on Ash's personal growth as he works closely with Professor Oak. Maybe Oak teaches Ash more about Pokémon history and lore, which in turn helps Ash become a better trainer. For example, learning about the ancient powers of certain Pokémon could give Ash an edge in battles. Ash could then share this knowledge with his friends and other trainers.
Obviously, the main characters would be Professor Oak and Ash's mom. Professor Oak is known for his vast knowledge of Pokemon, and Ash's mom is important as she is Ash's mother and has supported his Pokemon journey from the start.
One possible plot could be that Professor Oak discovers a rare Pokemon that he believes Ash's mom might be interested in. He then takes it to her to show her, and they end up having a long conversation about Ash's adventures and how proud they both are of him.
Another aspect that makes it appealing is the exploration of different themes. It could be about growing up, as Ash matures under Oak's influence. Or it could be about friendship that defies age and social roles. Some fanfictions also play with the idea of time - travel, where Oak and Ash interact in different time periods, adding a whole new layer of intrigue to their relationship. It's this flexibility and the ability to re - imagine their relationship that draws people to 'professor oak x ash fanfiction'.
