In the Kalos Region, a new evolutionary form called Mega Evolution has been introduced. The question is, can all Pokémon undergo Mega Evolution? This tale follows a young trainer named Alan and his partner, Lizadon (Charizard). Alan's goal is to "defeat all Mega Evolution Pokémon to reach the summit of strength." Along their journey, Alan and Charizard cross paths with Mega Absol and Mega Gaburias (Mega Garchomp) and engage in battles with them. Moreover, they will challenge Zumi (Siebold), a member of the Kalos Elite Four - does Siebold possess a Mega Evolution Pokémon as well? What motivates Alan's intense fixation with Mega Evolution, and what is the true purpose of his expedition?
