One of the greatest challenges could be taming the wild and powerful dragon Pokémon. Dragons are known for their fierce independence, and getting them to trust Ash would be no easy feat.
Ash might also face challenges in terms of the resources needed to train dragon Pokémon. Dragon Pokémon often require specific types of food and training environments. Securing these resources could be a constant struggle for Ash. Moreover, there may be a negative perception from some people who think dragon Pokémon are too dangerous to be trained, and Ash would have to overcome this prejudice as well.
Ash could become more confident and wise as a Dragon Master. His decision - making skills would improve as he deals with powerful and often unpredictable dragon Pokémon.
In some fanfictions, Ash's journey as a dragon master begins due to a competition. There is a dragon - Pokémon - related competition announced, and Ash, always eager for new challenges, decides to focus on dragon Pokémon to participate. He starts from scratch, learning about their behaviors, strengths, and weaknesses, and gradually builds his team of dragon Pokémon.
A really interesting plot might be that Ash is chosen by an ancient dragon deity to be its champion. As a Dragon Master, he has to go on a quest to collect special dragon orbs scattered across different regions. Each orb gives him new powers or abilities related to dragon Pokémon. Along the journey, he faces challenges from other trainers who also want the orbs for their own purposes.
In many fanfictions, Ash achieving the status of a Pokemon Master often involves him having extraordinary battles. He might defeat powerful legendary Pokemon that no one has ever tamed before. His Pikachu could evolve into a more powerful form, which gives him an edge in battles. Also, his bond with all his Pokemon, not just Pikachu, becomes so strong that they can execute complex strategies without any communication barriers.
It could be a famous Pokémon trainer. Maybe someone who has traveled to many different regions and has a lot of knowledge about rare Pokémon.
One idea could be that Ash discovers a hidden power within himself that allows him to communicate directly with Legendary Pokemon. This power sets him on a journey to understand the secrets of the Legendary Pokemon world. He might start by having an encounter with Mew, who guides him to different places where he can learn more about his new ability.
A good fanfiction would have Ash develop in a believable way. For example, instead of suddenly being super - powerful, he could gradually gain the skills and knowledge to become a Legendary Pokemon Master. He might start by learning about the unique habitats and behaviors of Legendary Pokemon from Professors like Oak.
In this fanfiction, Ash might have to face a crisis that threatens the entire Pokemon world. By using his skills, the strong bond with his Pokemon, and his experience from countless battles, he could save the world. This heroic act would earn him the respect and recognition needed to be declared a Pokemon Master. He might also gain some new and powerful Pokemon allies during this adventure.
One popular storyline is Ash finally achieving his long - dreamed - of victory in the Pokemon League with his Pikachu by his side, facing off against powerful opponents he has met throughout his journey. Another is Ash traveling to a new, mysterious region filled with undiscovered Pokemon species and having adventures there. Also, there are fanfictions where Ash forms an even deeper bond with his other Pokemon, like Charizard, and they go on special quests together.
The exploration of different relationships makes it interesting. Maybe Ash forms a deep friendship with a Pokemon that is considered an outcast in the Pokemon world. Their bond and how it helps Ash on his journey to becoming a master can be really engaging. Also, seeing Ash interact with characters from different regions in new ways, like having a cultural exchange of Pokemon training methods, adds depth to the story.
