In fanfiction where Ash turns into a Pokemon, there are numerous possibilities. One is that he could form a deeper bond with other Pokemon. Since he is now one of them, they might trust him more instinctively. He could also be hunted by some trainers who see him as a rare or powerful Pokemon.

And his old friends like Pikachu might have a hard time adjusting to this new Ash - Pokemon hybrid existence.
Maybe a powerful and evil pokemon trainer who has a vendetta against Ash. Now that Ash is in a vulnerable pokemon form, this trainer could try to capture and control him. The trainer might have some dark motives related to using Ash's unique situation to gain power in the pokemon world.
Well, if Ash turns into a legendary Pokemon, he'd likely gain a whole new set of powers. For example, if he becomes Arceus, he'd have the power to create and shape the Pokemon world.

But Ash, being Ash, would still have his kind heart and would use his powers for good.

So, by turning him into a Pokemon, it hopes to disrupt the balance and order that Ash has been a part of maintaining.
