Who could be the main characters in 'ash becomes a glacion fanfiction' besides Ash?

Latios would obviously be a key character. Also, Pikachu, Ash's loyal Pokémon partner, would be there. Maybe Misty or Brock could also be part of the story, with them either supporting or being skeptical of Ash's newfound admiration for Latios.

Pikachu would definitely still be there. It's Ash's most loyal companion, and it would be interesting to see how their relationship might change now that Ash is a girl. Maybe Pikachu would be more protective or show a different kind of affection.

One idea could be that Ash discovers the beauty and power of Glacion and decides to study it intensively. He might start a journey to find rare Glacion-related items or places. For example, he could search for a hidden Glacion temple where ancient secrets about it are stored.

Brock could also be a main character. Since he has knowledge about Pokémon care and breeding, he could be Ash's colleague in the fanfiction. They could work together on projects related to Pokémon health and nutrition.

Well, Pikachu could still be a main character. Even if Ash hates everyone, Pikachu might be the one trying to bring back the old Ash. Maybe Team Rocket could also be main characters. They are always around Ash, and his new - found hatred could make their interactions even more interesting. They might be confused by his change or even try to take advantage of it.

May could be one of the main characters. She could join Ash on his journey and share her knowledge about Hoenn's Pokemon with him. Another could be Brock, still tagging along to offer his expertise in Pokemon care.

It could be that there is a young, impressionable character who looked up to Ash Aura. After the betrayal, this character is confused and starts to question his own beliefs. There might also be a powerful mage in the story who has the ability to see the truth behind Ash Aura's actions and is trying to prevent the chaos that the betrayal has caused.

Mallow is another great choice. With her love for cooking and Pokémon, she could use her skills to create special Pokémon food for Ash's team. This could lead to some fun and heartwarming moments between them, and also bring the whole harem together as they enjoy the food.

His best friend from before the war could be a main character. This friend might have been waiting for Ash's return and now has to deal with the changed Ash.

Pikachu, of course. It's always been Ash's closest partner.
