Ash is the central character. Alongside him, May is crucial as she brings her own story and development. Brock, with his medical and Pokémon - handling skills, is always there for support. Professor Birch also plays a role, being the local Pokémon expert who can offer guidance to Ash. Hoenn's Elite Four members are significant as they represent the ultimate challenges for Ash in his journey towards becoming a better trainer in the Hoenn region.
Ash is almost surely a main character in this fanfic. In addition to him, there could be antagonists like Team Magma or Team Aqua leaders. Also, his traveling companions, who might be his friends or other trainers he meets along the way in Hoenn. His Pokémon, such as Pikachu, are also bound to be key characters as they accompany him on his adventures and battles.
Some fanfictions focus on Ash's growth as a trainer in Hoenn. He might learn new battle strategies, for example, adapting to the different types of Pokémon prevalent in Hoenn. There could be plot points around his interactions with Hoenn - native Pokémon species that he hasn't encountered before. And his experiences with the different cultures and traditions in Hoenn can also be central to the story, as he tries to understand and respect them while on his journey.
In many fanfics about Ash's Hoenn journey, his character development is often a key aspect. He might face new challenges that are different from the anime. For example, he could have more complex relationships with his Pokémon. The fanfic might also explore different storylines for his gym battles, like facing stronger opponents or having to use new strategies.
I'm not sure specifically as I haven't read this particular fanfic. But generally, it might be about Ash's adventures in the Hoenn region with an emphasis on his aura abilities. It could involve his battles, encounters with different Pokémon, and his growth as a trainer in the context of Hoenn.
He might meet a mysterious old trainer who imparts some unique wisdom. There could also be a young and talented trainer who becomes his rival or friend.
The special thing about Ash's Hoenn journey fanfic is that it allows for creativity. Writers can give Ash different personality traits or make him face situations that the official story didn't cover. For instance, he could be more confident or more hesitant in certain situations, which would change the whole dynamic of his journey.
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.
One possible fanfiction could be about Ash's adventures in Hoenn during the month of May. Maybe he discovers a new Pokémon species that is only active during this time of the year. He could be traveling with his usual companions and facing challenges specific to the Hoenn region.
In this Hoenn fanfiction, Ash and May could be on a quest to find a special item that is said to have great power. They face various obstacles and meet different characters along the way. Their different personalities - Ash being more impulsive and May being more level - headed - would play a big role in how they overcome these challenges.
One of his toughest opponents could be Tyson. Tyson was a very strong trainer in the Hoenn League in the original series. His Pokémon were well - trained and had unique battle strategies. Ash would have to really bring his A - game to defeat him.
