I'm not entirely sure as I haven't read this specific novel. But generally, it might be about the emergence and growing power of dark - type Pokémon. It could involve their interactions with trainers, battles against other Pokémon types, and how they are changing the Pokémon world.
There could be a trainer who has a special bond with dark Pokémon as one of the main characters. Maybe also a Pokémon researcher who is trying to understand the sudden rise of dark Pokémon. Another possibility is a powerful dark Pokémon that plays a central role in the story, with its own personality and goals.
In Unova - based fanfiction, if Ash gets involved with dragons, it could be an amazing story. Maybe he befriends a baby dragon Pokémon that has been separated from its family. Ash then has to protect it from poachers or other dangerous Pokémon. Along the way, he forms a strong bond with the dragon, and this bond could change his approach to Pokémon training completely. He might start to focus more on the emotional connection with his Pokémon rather than just battle strategies.
One possible scenario in this fanfiction could be that Ash has to overcome his toughest opponents yet in Unova. He might face trainers with unique and powerful Pokémon that he has never encountered before. His Pikachu would surely play a crucial role, using its speed and electric attacks to outwit opponents.
One idea could be that Ash and Misty visit Unova for a Pokemon tournament. They meet new friends and face new challenges together. Misty could use her water - type Pokemon in creative ways against the Unova Pokemon's unique types.
In Unova fanfiction, one difference in Ash could be his relationships. He might have more complex friendships or rivalries compared to the main series. For example, his bond with his Pokémon could be explored in greater depth, like how he trains and communicates with them on a more emotional level.
In this fanfiction, Ash and Dawn's adventures in Unova could be filled with new Pokemon encounters. Ash might bring his typical enthusiasm and determination, while Dawn could add her own unique charm and Contest skills. They could team up to face new challenges, like strong Gym Leaders in Unova. Their friendship would also likely develop further as they explore this new region together.
In a fanfiction of Ash in the Unova League, it could focus on his relationships with his Pokemon during this journey. Maybe Pikachu has a special moment of growth, or he catches a new and rare Pokemon that becomes crucial in his battles in the league.
In fanfiction, Ash in Unova might get the chance to ride a dragon - type Pokémon. This would be an incredible experience for him. It could also open up new areas for him to explore in the Unova region, areas that are only accessible by air or with the help of such powerful Pokémon.
