This could lead to him having new abilities and forming unique bonds with Pokémon that are also attuned to the aura.
One scenario could be that Serena is trapped in a collapsing cave. Ash uses his aura to sense the safest path to reach her and then uses aura - enhanced strength to move the large rocks blocking her way. Another is when Serena is poisoned. Ash's aura could be used to purify the poison in her system, similar to how some Pokémon can use their powers to heal. He focuses his aura on her body, and the positive energy slowly drives out the toxins.
In the fanfiction, Ash may face the challenge of range. If Dawn is far away from him, his aura might not be able to reach her in time to protect her. Also, if he has to face an enemy who can manipulate or counter his aura, it would be really difficult for him to protect Dawn. For example, if there is a villain who can send out waves of negative energy to disrupt Ash's aura, he would have to find a way to overcome this while still keeping Dawn safe.
