Bio & Pokemon Teams

I'm taking the concept of this story from Yuvraj_007 but it will be different.

This story takes place after Tapu-Koko wishing Ash good luck for his Masters 8 battles

A lot of Ash's previous league results will be different and he will have a few more and different Pokemon in this story as I do intend on rewriting the entire series from the start which will connect with this story.
