Her relationships with other characters would be different. With male characters like Brock or Gary, there could be a different kind of dynamic. Maybe there's a bit of a romantic undertone in her interactions with Gary, which was not really present in the original with male Ash. And with Brock, she might be more of a role model for him in terms of being a trainer.
His physical abilities change too. He might be stronger and faster as a werewolf. This could lead to a change in his confidence level. He might be more bold in battles, but also more cautious as he doesn't want to fully expose his werewolf side. He has to find a balance between using his new powers and still being the Ash his friends know and love.
In such fanfictions, Ash may become more in tune with Pokemon instincts. For example, if he transforms into a Pikachu, he might be more skittish or easily excited like a real Pikachu. His decision - making could also be influenced by the new form's nature.
In this fanfiction, Ash's character development might involve him becoming more empathetic. He could meet Pokemon or characters in the Lunar region who are in difficult situations. For example, if there are Pokemon being exploited in the Lunar region, Ash would step in to help. This would make him grow as a person and a trainer. Also, his understanding of different types of Pokemon and their needs could expand, since the Lunar Pokemon might have different requirements compared to the ones he's used to. He might also develop new skills in communication, if the Lunar region has its own way of communicating with Pokemon.
Ash develops by learning new strategies. In Pokemon Conquest, battles are different, so he has to adapt, which makes him more versatile. He also develops his relationships with new Pokemon, which broadens his understanding of different Pokemon types.
It changes the story in many ways. Ash would likely have some latent powers. Maybe he could communicate with Pokemon on a deeper level without the need for a lot of training. His battles could be different too. Opponents might be more hesitant to face him once they learn of his relation to Arceus. And in terms of the plot, it could introduce a whole new arc about Ash uncovering his true identity and what it means to be the son of Arceus.
When she is a rich princess in fanfiction, Hermione may become more diplomatic. Since she is part of the upper echelons of society, she has to deal with political intrigue and maintain good relations with other kingdoms or powerful families. This could lead to her developing skills in negotiation and compromise, which is a change from her more straightforward, academic - focused self in the original story.
In these fanfictions, Ash often becomes more confident. Since he is the chosen one, he has a greater sense of purpose. For example, he may be more decisive in battles, quickly choosing the right Pokemon to send out.
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.
His view of victory and defeat changes. In the regular series, winning battles is about skill and strategy with his Pokemon. But as a demon - influenced Ash, he might start to see victory in a more cut - throat way, which could lead to him making decisions that he wouldn't have made before. This change in his character development makes the fanfiction story very different from the original Pokemon narrative.
Ash may also interact with Latios in a way that involves mutual growth. Latios could teach Ash about the importance of protecting the natural balance in the Pokemon world, and in return, Ash could show Latios the value of human - Pokemon friendship. Their relationship could evolve as they both learn from each other and face different obstacles, such as evil teams trying to capture Latios or disrupt the peace in the Pokemon regions.
