A really interesting plot could be that an old, powerful Pokemon relic has been discovered. Ash and Professor Juniper embark on a journey to study it. However, a group of villains also wants the relic for their own malicious purposes. Ash and Professor Juniper must not only protect the relic but also figure out its true nature and powers.
Perhaps Ash has a strange dream about a powerful Pokémon that only Professor Juniper seems to have some knowledge about from ancient texts. They team up to try and find this Pokémon, but they have to compete with a rival group who also want to get to it first. In the process, Ash learns a lot from Professor Juniper's wisdom and research skills.
One way is through a crisis situation. Let's say a powerful and dangerous Pokemon is on the loose. Ash and Professor Juniper have to work together to calm it down. During this process, they learn about each other's strengths and weaknesses. Ash sees Professor Juniper's courage and intelligence in handling the situation, and Professor Juniper admires Ash's determination and connection with Pokemon. This mutual admiration can lead to a stronger relationship.
One idea could be a story where a young trainer teams up with Professor Sycamore to research a new and mysterious Pokemon species that has been causing strange phenomena in the Kalos region. They embark on a journey filled with challenges and unexpected encounters.
One interesting idea is that a group of rogue ninjas in the Naruto world steal some of the Pokemon professor's research. They think they can use it to gain power over both the Naruto world and the Pokemon world. So, the professor teams up with some Naruto heroes to get the research back and prevent chaos from ensuing. As they work together, they learn a great deal about each other's worlds and abilities.
Another idea for a fanfiction could be that Ash and Juniper accidentally get transported to a parallel Pokemon world. In this world, the rules are a bit different, and they have to rely on each other's skills. Ash's battle experience combined with Juniper's research knowledge would be crucial for them to find a way back home.
Maybe in the fanfiction, Elesa's Pokemon get lost in an unknown region and Ash offers to help her find them. During their search, they encounter rare and powerful Pokemon, and they also discover a hidden mystery about the region that they are in. This adventure could strengthen their friendship and respect for each other.
A possible plot is that Ash is separated from his friends during a powerful storm. Alone, he stumbles upon an ancient Pokemon ruin. He then has to decipher the secrets within the ruin with the help of his Pokemon, all while trying to reunite with his friends. He might learn some long - forgotten Pokemon training techniques in the process.
One idea could be that Ash mentors a young trainer who is afraid of Pokemon battles. Ash uses his own experiences to show the kid how to overcome fear and build a bond with their Pokemon. For example, he might share how he was once scared of facing strong opponents like Brock in his early days but learned to trust in Pikachu's abilities.
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.
