Here What I would like-
After winning the World Pokemon Tournament & becoming world champion , Ash finds out that his father is infect a Legendary Officer of ''International Police'' after his mother get kidnap by his father's enemy and Ash rescue to her with a help of ''unknown individual'' ! Therefore , Ash decide to join The ''International Police'' in hope of meeting his father someday . However he has to take 3 year of intense training in ''International Police Academy'' before he become an Officer .
Next Gen , Ash goes to new region to investigate an Evil Team while helping the main character from game to win Gym Battle and looking for his father !!!
Let me honest , Its much better then watching the same eternal Loop of Ash going to new region , making new friend , Beating Gym leader and getting ass-kicked in the League .
