One possible fanfic could be that Ash is on a journey through a mysterious forest. He senses an otherworldly presence. Suddenly, Ho - Oh appears, its feathers glowing. Ash, with his unwavering determination, throws a Poké Ball. Against all odds, the Poké Ball shakes once, twice, and then clicks, signifying he has caught Ho - Oh. This would completely change the dynamic of his journey and his status as a Pokémon trainer.

He meets Ho - Oh there, and instead of using a traditional Poké Ball, he has to use a special item or perform a unique ritual.
