That Story of Ash being betrayed caught my attention since it is not the typical story of Ash's Betrayal, since here he is more evil as usually happens in few stories
Speaking of, you would be able to make a new story of Ash betrayed but it would be more different where he would be a tyrant conqueror and destroyer, and like every king he will also need his queen, To be the new masters of the world in this story with a more evil Ash but affectionate with his partner
Note: if you are interested in making this request I can give you the summary and details of the story
