A possible plot could be a tournament. Chesnaught and Greninja both enter a high - stakes Pokémon tournament. They meet in the semi - finals and have an intense battle. But then they realize that there is a conspiracy behind the tournament, and they join forces to expose it.
One idea could be that Chesnaught and Greninja are on a quest to save their forest home from a mysterious dark force. They start as rivals, each thinking their own way is best to protect the forest, but as they face challenges together, they learn to work as a team.
One great greninja x delphox fanfic is 'The Bond Beyond Types' on FanFiction.net. It delves deep into their unique relationship, exploring how their different natures and abilities complement each other in unexpected ways.
The contrast between greninja's sleek, ninja - like nature and delphox's more elegant and magical aura. Their combination in a fanfic can lead to really cool interactions and storylines.
The combination of their abilities is also crucial. Greninja's water - type moves and its acrobatic fighting style along with Delphox's fire - based attacks and psychic - like abilities can create interesting battle scenarios and story arcs in the fanfic.

I'm not a big fan of yaoi fanfiction in general, but in the case of Greninja and Ash, it often involves a creative exploration of their relationship in a non - canonical way. Some of these fanfictions might focus on their strong bond and translate it into a more romantic or emotional connection that goes beyond friendship as seen in the original Pokemon series.
The 'alola greninja returns fanfic' might focus on Greninja's journey back to Alola. It could start with Greninja feeling a pull towards Alola, perhaps due to some unfinished business or a connection it still has with the place. Once there, it could encounter various Pokemon and trainers. There might be a story arc about Greninja finding its place again in Alola, dealing with changes that have occurred since it was last there, and forging new relationships while also rekindling old ones.
