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.
The appeal might be the unique dynamic. Delia is Ash's mother and Oak is a respected figure in the Pokemon world. In fanfiction, it could be about exploring a different side of their relationships, perhaps a romantic or a more complex emotional bond that isn't shown in the original series. It gives fans the chance to be creative and rewrite the characters in a new light.
Well, in some of these fanfictions, there could be stories where Ash and Professor Oak go on unique adventures not seen in the original series. Maybe they discover a new type of Pokemon together.

Regular Pokemon fanfiction usually focuses on things like Pokemon battles, trainer adventures, or the growth of the main characters like Ash.

I'm not sure specifically as there could be many different plots in a 'pokemon green oak fanfic'. It might revolve around Oak's adventures in the Pokemon world, his research, or his interactions with trainers and Pokemon.
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.
Ash could be paired with Professor Oak in a fan fic. Ash could return to Pallet Town and have a series of adventures with the professor, like helping him with a new research project on Mega Evolutions. They could also travel together to a new and uncharted region.
