Pokémon: Ascension Trainer System

After transmigrating into the world of Pokémon, the protagonist awakens in Pallet Town as a six-year-old Ash Ketchum—before his journey even begins. But this time, things are different. He possesses both the Aura and Viridian Powers, along with the memories and knowledge of a Pokémon Master from another life. Armed with foresight of everything to come—the challenges, the rivals, and the painful regrets—Ash vows to rewrite his destiny. No longer will he be the “Release Master” who lets his partners fade away in Professor Oak’s backyard, or the ten-year-old forever restarting in every new region. The mistakes of the past will be erased. In this life, Ash will command true power, and become the greatest Pokémon Trainer the world has ever seen. [Note: This is a work of fiction.
