Perhaps in the fanfiction, the ash aura tree is a portal to another dimension. People from different worlds discover this and try to either control the access to it or use it for their own purposes. The tree's aura could also have healing properties, and a story could revolve around a healer who uses the tree's power to cure a plague in a village.
One idea could be that the ash aura tree is a magical entity in a fantasy world. It could be the source of power for a group of heroes. They have to protect it from dark forces who want to use its power for evil. Another idea is that the tree has a sentient spirit within it that can communicate with a chosen individual, guiding them on a journey of self - discovery.
Perhaps Ash's Aura Guardian abilities are linked to a forgotten Pokemon tribe. He goes on a journey to find this tribe and in the process, he learns new techniques and forms strong bonds with unique Pokemon. This could involve facing many challenges and making new friends along the way.
Well, a plot could revolve around a new villain who has the ability to manipulate the Dark Aura. This villain targets Ash because of his strong bond with his Pokémon. Ash then has to explore the origin of the Dark Aura to find a way to defeat this new threat. He might encounter ancient Pokémon along the way that have knowledge about the Dark Aura. And as he delves deeper, he discovers secrets about his own connection to this powerful force.
A fanfiction might explore the idea of Ash sharing his aura with his Pokemon. This could create a special bond that goes beyond the normal trainer - Pokemon relationship. For example, his Pikachu could gain enhanced speed and strength due to the shared aura, and they could overcome seemingly impossible obstacles together.
Ash's aura powers in fanfiction might also enable him to communicate with Pokémon on a deeper level. He could understand their emotions and intentions more clearly, leading to better teamwork in battles and stronger bonds outside of combat. It's like he has a psychic connection with them through his aura.
I'm not sure specifically as I haven't read this particular fanfiction. But generally, it might involve Ash using his aura to communicate with the tree, perhaps to gain some sort of power or knowledge from it.
One interesting plot could be Ash discovers he has an aura - related psychic power that allows him to communicate with Pokémon on a deeper level. He uses this power to understand their emotions and needs better, leading to stronger bonds and more successful battles.
One possible plot could be Ash discovers a new form of Aura that is unique to the Alola region. This new Aura power helps him in his Pokémon battles, giving him an edge against tough opponents like the Island Kahunas. He could also use it to better understand and communicate with his Pokémon, deepening their bond.
First, you should define the role of the ash aura tree. Decide if it's a good or bad entity. For example, if it's good, you can start with a description of its beauty and the positive influence it has on the surrounding area. Then, create a main character who has a connection to the tree, like a guardian or a seeker of its power.
Again, without having read it, it's hard to say for sure. But it could include his Pokémon partners, as they are often by his side in his adventures.
In a 'Naruto Aura Guardian' fanfiction, you could focus on the relationships within the Aura Guardian community. For example, there could be different factions among them with varying beliefs about how to interact with the ninja world. One faction might want to stay hidden and only protect their own secrets, while another believes they should actively help the ninja villages. A story could revolve around a young Aura Guardian who has to choose which faction to side with, and how this decision impacts his relationships with Naruto and other key characters in the Naruto universe.
