Pokémon: The Strongest Ash Ketchum

In the first chapter, there are four major systems. Please read the explanation in detail. Thank you. The reason for the many mythical beasts is explained in which chapter of Rainbow Gym. It is an adventure story about a time traveler who becomes Ash Ketchum. If you have any suggestions, please write them in the comment area. I will read them. I will try my best to write the Ash Ketchum that everyone wants to see. The legendary Pokémon Dream Beast will also be conquered.
