Definitely Pikachu. Pikachu is one of the most recognizable Pokémon, and having it interact with Arceus in a crossover would be really cool. It could be like a small, cute Pikachu following around the all - powerful Arceus.
A fun plot could be Arceus crossing over into a world of magic like in the Harry Potter universe. It could be a strange and interesting encounter as Arceus, a powerful Pokémon god, enters Hogwarts. The students and professors would be both amazed and a bit scared perhaps. And Arceus would have to navigate this world of spells and wizards while also trying to find a way back to its own realm.
A powerful and ancient Pokémon from a long - forgotten era could be the cause. This Pokémon might have a grudge against Arceus for some past event and has finally found an opportunity to strike and hurt it. For instance, if Arceus had banished this Pokémon in the past, it could now be seeking revenge.
One possible plot could be that the Jewel of Life has been stolen from its rightful place. Arceus chooses a young and brave Pokémon or human to retrieve it. Along the way, the protagonist discovers the true nature and power of the jewel and has to face many challenges, like traversing dangerous terrains and outsmarting cunning enemies.
Maybe an ancient Pokémon that has been in slumber for ages wakes up and realizes the importance of the Jewel of Life. So, it becomes the main character and embarks on a journey to safeguard it. This Pokémon could have unique powers that help it in this mission.
I'm not sure exactly how many fanfictions exist where Ash is the son of Arceus, but it's a very interesting concept. It could lead to all kinds of plot twists. For example, Ash might have some hidden powers or a special connection to the Pokémon world that others don't. This kind of fanfiction can explore the relationship between Ash and Arceus in ways that the original series doesn't.
In 'ash raised by arceus fanfiction', one could expect a lot of creative elements. For example, Arceus being a god - like Pokémon might raise Ash in a way that completely changes his understanding of the Pokémon world. It could involve Ash learning secrets about Pokémon that no one else knows, and this might lead to new adventures and challenges for him.
Fanfiction about Giratina and Arceus can take many forms. Some may focus on epic battles between them, imagining different scenarios where their powers clash. Others might delve into their creation myths and how they are connected in the fan - created universe. For example, a story could explore how Giratina's banishment to the Distortion World by Arceus affected its personality and its view of the other Pokemon and the world itself.
There might be. Fanfiction writers love to create crossovers and unique scenarios. Since Naruto and Arceus are from different fictional realms (Naruto from the ninja world and Arceus from the Pokémon world), a story with Naruto as the father of Arceus would be quite an out - of - the - box concept. It could involve some complex world - building and character development to make it work.
There might be some new characters introduced in the fanfiction. A mysterious Pokemon trainer who has some ancient knowledge about Arceus and can guide Ash. Or perhaps a group of Pokemon researchers who have been studying the relationship between Arceus and the world for a long time. These characters could add more depth to the story, providing different perspectives on the situation between Ash and Arceus, and helping Ash in his fight against the perceived betrayal.
