One great aspect of Aura Guardian Ash fanfiction could be the exploration of Ash's latent aura powers. Maybe in these stories, Ash discovers he has a much deeper connection to the aura realm than he ever knew. This could lead to him having new abilities and forming unique bonds with Pokémon that are also attuned to the aura.
It could be that there is a young, impressionable character who looked up to Ash Aura. After the betrayal, this character is confused and starts to question his own beliefs. There might also be a powerful mage in the story who has the ability to see the truth behind Ash Aura's actions and is trying to prevent the chaos that the betrayal has caused.
In fanfiction, Ash might discover a special water - type stone that enhances his bond with his water - type Pokemon. This stone could have the power to boost their abilities and his own understanding of them. With this new advantage, he enters water - type Pokemon tournaments and gradually builds his reputation as a water master. He also shares his experiences with his friends, who support him in his journey.
One possible plot could be that Ash travels to a new and mysterious region. There, he discovers a rare type of Pokemon that has unique powers. He befriends this Pokemon and together they face challenges from a new evil team. Through their bond and his determination, Ash gradually overcomes all the obstacles and gets closer to becoming a Pokemon master.
I'm not entirely sure specifically what 'ash uses aura fanfiction' is about without more context. It could be a fan - made story where the character Ash makes use of aura in some way that's different from the original source material.
In a fanfiction, Ash and Serena might explore their auras together. Serena, having a more refined sense of aura, could teach Ash how to better control and understand his. This could lead to a series of adventures where they use their auras to communicate secretly and solve mysteries in the Pokemon world.
It depends on your personal taste. If you're a big fan of the Aura Guardian concept and like stories centered around Ash, it could be a great read. Some fanfictions really capture the essence of the characters and expand on the lore in interesting ways.
There's no canonical indication that Ash uses his aura abilities to see fanfiction. Fanfiction is a concept within the fan community, not something directly related to the in - universe powers in the Pokémon world.
One common theme is adventure. Aura Ash often goes on exciting quests in many fanfictions. Another theme is friendship. She forms strong bonds with other characters while on her journey.
I'm not sure specifically what that particular 'ash unlocks aura fanfiction' is about without reading it. It could be about a character named Ash who somehow unlocks an aura in a fictional story, perhaps in a world of magic or superpowers.
