There might be a girl trainer who is very skilled in battling but has a shy personality. She initially challenges Ash to a battle and after that, they realize they have a lot in common. They start sharing tips about Pokemon training and soon become friends. This friendship could then lead to various adventures together as Ash explores Unova.
Well, perhaps the story starts with Ash arriving in Unova and immediately stumbling upon a Gible. Gible could be lost or in some kind of trouble. Ash, being Ash, decides to help it. As they interact, Gible takes a liking to Ash and wants to join his team. Ash then has to figure out how to train Gible in the Unova region, which has different Pokémon and training styles compared to other regions he has been to. They might enter local tournaments together and slowly build a reputation in Unova as a formidable trainer - Pokémon duo.
In a new Ash Unova fanfiction, the main villain could be a scientist who is conducting unethical experiments on Unova Pokémon. He believes that by fusing different Pokémon together, he can create the ultimate Pokémon. His experiments are causing harm to the Pokémon involved and are also disrupting the natural balance in the Unova region. Ash discovers what's going on and has to stop the scientist, not only to protect the Pokémon but also to save the Unova region from the potential disasters that could be caused by these abnormal Pokémon creations.
He could defeat Trip. Trip is a well - known character in the Unova region. Ash might have finally outsmarted Trip in a battle with his Pikachu's speed and powerful electric attacks.
A powerful and greedy Pokémon collector could be the main antagonist. He wants to capture all the rare Pokémon in Unova for his own collection, regardless of the consequences for the Pokémon or the ecosystem. He sees Ash and May as obstacles in his path, especially when they try to protect the Pokémon they encounter.
One idea could be Ash starting in Unova with a new set of Pokemon he catches right away. Maybe he meets a unique and rare Pokemon that no one has seen before in that region. Another could be that he has to face a new type of villainous team that has different motives compared to the ones in other regions.
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.
Ash could become more patient. Since Gible might be a bit difficult to train at first, Ash has to learn to be patient with it. He might also become more adaptable as he has to adjust to the Unova region's unique Pokémon and training methods while training Gible.
Well, it could be about Ash and Misty exploring the Unova region, facing new Pokémon and making new friends. Maybe they join some local Pokémon contests or battles in Unova.
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.
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.
