Definitely. There could be a character who is a bit of an outcast in the Orre region but has a special bond with a powerful and rare Pokémon. This character might be shunned by others but Ash sees their potential. Then there's the possibility of a merchant who travels across Orre and has all sorts of interesting items related to Pokémon. He could be a source of information for Ash about the region's hidden treasures and secrets. Also, a young Pokémon healer who has a kind heart and helps Ash's Pokémon when they get injured during battles.
Yes, in Ash Champion of Orre fanfiction, there are likely other memorable characters. There might be a local Pokémon ranger who helps Ash navigate the dangerous parts of Orre. This ranger could have a deep connection with the local Pokémon and know their secrets. A female trainer who is known for her beauty and strength could also be a part of the story. She might initially be a bit of a mystery to Ash but later becomes an important ally. And don't forget about the local Pokémon breeders who might introduce Ash to new Pokémon breeding techniques specific to Orre.
One reason it's appealing is the character of Ash. He's a well - known and beloved character. In the Orre region setting of the fanfiction, new adventures and challenges await him. The unique environment of Orre, which might be different from the usual Pokémon regions, offers a fresh backdrop for his journey. His skills as a trainer can be explored in new ways, facing different types of Pokémon and trainers. Also, fanfictions often allow for more creative interpretations of his relationships with other characters, whether they are his friends or rivals.
The unknown champion could be a reclusive hermit - like character who has been living in seclusion in a forest. They have trained their Pokémon in harmony with nature and have a very different approach compared to the more mainstream trainers. Maybe they are an old - timer who has seen different eras of Pokémon training.
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.
The OC themselves are often popular characters. Since they are original creations, they can have all sorts of unique personalities, abilities, and backstories. For example, an OC could be a shy but brilliant Pokemon trainer who gradually overcomes their insecurities with Ash's help.
Pikachu would most likely be there. Since Pikachu is Ash's closest companion, it would be involved in any story related to Ash. Maybe Pikachu could also have some sort of interaction with Mew, like being a bit jealous at first of Ash's new connection with Mew.
Well, in an 'ash unknown champion' fanfiction, the plot might involve Ash getting lost in a mysterious region. There, he stumbles upon an unknown champion who is facing some sort of problem, like a group of poachers targeting their rare Pokémon. Ash decides to help the champion, and in the process, they exchange their Pokémon training techniques. As they work together, Ash realizes that there are so many new ways to approach Pokémon battles that he hadn't known before.
Pikachu is always an interesting character in these fanfictions. In some stories, Pikachu might develop new abilities or have a deeper understanding of the Pokemon world that it can share with Ash. Another character could be Gary. He can be portrayed as a more complex rival, perhaps with his own hidden motives or a change of heart towards Ash. And then there's Misty. She can have new storylines in fanfictions, like being a powerful water - type Pokemon trainer with her own unique training methods that Ash can learn from.
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.
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.
Obviously, the Legendary Pokemon would be a main character. It could be a Pokemon like Mewtwo, who is often depicted as having a complex personality. It might start off as a mysterious and powerful entity that Ash has to befriend or battle against.
