One idea could be a story where the balance between the different dimensions overseen by Dialga (time), Palkia (space), and Giratina (the distorted world) is disrupted. Arceus, as the creator deity, has to step in. Maybe a powerful, unknown force is causing chaos, making time and space fold in on each other. Giratina, usually banished to the Distortion World, finds itself drawn back into the normal world, causing all sorts of mayhem. Dialga and Palkia try to fix things on their own but realize they need Arceus' help. The fanfic could focus on their journey to restore order and the sacrifices they might have to make along the way.
A plot twist could be that the powers of Dialga, Palkia, and Giratina are actually interchangeable. In a moment of extreme crisis, they merge their powers and identities, creating a new, super - powerful entity. This entity has the combined abilities of controlling time, space, and the distortion world. However, this also comes with a cost as they lose their individual identities. Arceus then has to decide whether to allow this new entity to exist or try to separate them back into their original forms.
Another theme is redemption. Giratina is an exiled Pokemon, and in many fanfics, its relationship with Dialga can be a path towards redemption. For example, Dialga may offer a way for Giratina to atone for its past actions through their connection.
There could be a plot where a female Dialga takes on a human form to be closer to Ash. She disguises herself and joins Ash on his journey. Along the way, they face various challenges together, like dealing with other powerful Pokémon or trainers who oppose them. As they overcome these obstacles, their relationship deepens. It could also start with Ash having a strange encounter with a female Dialga in his dreams, and then he starts to search for her in the real world, leading to a series of adventures and the growth of their relationship.

Well, 'ash and dialga fanfiction' could be about many things. Maybe it's a story where Ash, from the Pokémon world, has an encounter with Dialga. It could involve Ash trying to catch Dialga or them teaming up for some great adventure against other powerful Pokémon or threats in the Pokémon universe.
First, you need to understand the character of Palkia. Since it's female in this case, think about how a female Palkia might behave differently from a male or the general Palkia. Then, come up with a plot. It could be something like Palkia's adventure in a new world or her relationship with other Pokémon. For the lemon part, you need to be careful and tasteful. Don't just jump into it. Build up the relationship and the tension first. For example, through their conversations and shared experiences.
Well, it could be about Naruto somehow getting involved with Palkia. Maybe Naruto discovers a new realm where Palkia exists and has to form an alliance with it to fight a common enemy. He might learn some new powers from Palkia that are different from his regular ninja skills.
It could be a dark entity that wants to use Palkia's power for evil. Maybe an ancient evil spirit that has been sealed away for a long time but now wants to break free and use Palkia as a key to unlock ultimate power. Naruto and Palkia would have to team up to stop it.
