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'.
Well, I've heard of 'Ash and Oak's Parallel Journeys'. This one is quite interesting as it imagines a scenario where Ash and Professor Oak are on parallel quests. While Ash is out there catching Pokemon and winning badges, Professor Oak is on his own journey related to Pokemon research, and eventually, their paths cross in a very unexpected and heartwarming way.
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 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.
Ash could also develop better leadership skills. As an assistant, he might have to lead small teams during research expeditions. He would need to make decisions quickly and fairly, considering the safety and goals of the team. This would be a big change from his usual role as a solo trainer, and it would shape him into a more well - rounded character in the fanfiction.
Another theme is growth. Both Gary and Ash grow as characters, learning from each other and becoming better versions of themselves. For example, Gary might learn more about Ash's kindness and Ash might learn from Gary's strategic thinking.
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.
