Another theme is the power of friendship. Ash's relationship with his Pokemon is central. When he meets Arceus, his Pokemon friends might play a crucial role in the encounter. For example, Pikachu could use its electric attacks to protect Ash if there's any danger during the meeting.
Well, the plot could involve Ash getting transported to a special realm where Arceus resides. Maybe Arceus sees something special in Ash and decides to test him. Ash could be given tasks that are related to saving the Pokemon world from a great danger that only he, with the help of Arceus, can prevent.
In such a fanfiction, Ash might gain some extraordinary powers. Since Arceus is a very powerful Pokemon, it could bestow upon Ash the ability to understand all Pokemon languages instantly. This would give him an edge in his Pokemon journey, allowing for deeper connections with his Pokemon and better strategies in battles.
The meeting would likely give Ash a new sense of purpose. He might shift his focus from just winning battles and championships to something more grand, like protecting the entire Pokemon universe. He could also meet new and rare Pokemon through his connection with Arceus.
Team Rocket might be main characters as well. They could be constantly trying to capture Ash or his Pokemon because of his special status. Their bumbling attempts to take advantage of Ash's link to Arceus could add a lot of comical and action - filled moments to the fanfiction. And of course, Arceus itself could be a major character, guiding Ash in some way or interacting with him directly.
One highly regarded story is 'Ash's Arceus Adventure'. In this fanfiction, Ash embarks on a journey with Arceus to stop an evil organization from stealing the essence of all the legendary Pokemon. The story is great because it combines action, mystery, and the unique bond between Ash and Arceus. Another good one is 'Arceus and Ash: The Legendary Bond'. It focuses on how Ash's pure heart and determination attract Arceus, and they work together to heal a sick Pokemon world. The detailed descriptions of the Pokemon and the emotions of the characters make it a top pick. And then there's 'Ash, Arceus, and the Time - Twisting Quest' where Ash travels through time with Arceus to prevent a cataclysmic event that would destroy the Pokemon timeline.
In this fanfiction, Ash's character development could be significant. Since Arceus is such a powerful and wise entity, Ash may start to think more strategically in battles. He might also become more empathetic towards Pokémon, as Arceus would likely instill in him a greater respect for all Pokémon. This could lead to him making different choices when it comes to capturing and training Pokémon, focusing more on their well - being and less on just winning battles.
One interesting plotline could be Ash's discovery of his special connection to Arceus. Maybe he starts having strange dreams or powers that lead him to uncover the truth. It could also involve Ash facing challenges from those who oppose his new - found status as the 'child of Arceus', like some evil organizations that see him as a threat to their plans.
A possible plot for a Pokemon Ash and Arceus fanfiction could be that Ash is summoned by Arceus to a sacred place. There, Arceus reveals that Ash has been chosen to help balance the powers of all the different types of Pokemon in the world. This would involve Ash traveling to different regions and facing challenges related to each type of Pokemon. For example, in a region dominated by fire - type Pokemon, he might have to find a way to cool things down without harming the Pokemon. Another plot could be that Ash accidentally angers Arceus, and as a punishment, he has to go on a journey to prove his worth and respect for all Pokemon. He has to complete tasks like helping a group of endangered Pokemon species thrive again. And, a third plot idea is that Arceus gives Ash the ability to transform into different Pokemon forms for a short time to better understand them, and Ash uses this power to solve various problems in the Pokemon world.
Ash could potentially have the power to control the elements related to Pokemon types. For example, if he encounters a fire - type Pokemon in trouble, he could use his ability to manipulate fire to help it. Also, he might be able to teleport between different regions of the Pokemon world, which would be a very handy ability for his adventures.
