Maybe in this fanfiction, Ash's transformation into a Zorua is a result of a scientific experiment gone wrong. As a Zorua, he discovers new abilities and a different perspective on the Pokémon world. He could use his new form to infiltrate a group of Zorua and Zoroark to learn their secrets and perhaps find a way to reverse the transformation. Along the way, he might have to prove himself to the other Zorua and earn their trust.
Perhaps a jealous trainer. This trainer has always been envious of Ash's success and now that Ash is in a vulnerable state as a Zorua, the trainer sees an opportunity to get rid of him for good. The trainer could try to use his own Pokémon to capture Ash or even harm him, making the trainer a formidable antagonist in the story.
