Pokémon Advanced Generation: Mew & the Wave Hero Lucario

Long ago, before the era of Poké Balls, there was a great Pokémon war. The hero Aaron and his Pokémon Lucario used the power of aura to quell the conflict, earning Aaron the title of "Wave Hero." A century later, Ash and Pikachu arrive in Oldroot City to participate in a Pokémon battle tournament and festival held in honor of Aaron. After winning the tournament, Ash is bestowed with the title of "Wave Hero" and granted the right to wield the "Hero's Staff" during the ceremony. However, just as the grand festival begins, Lucario—who had been sealed within the staff—awakens before Ash's eyes and reveals the secret that Aaron abandoned the city to flee! Meanwhile, the mythical Pokémon Mew suddenly appears and abducts Pikachu and Meowth. Guided by Lucario, Ash heads toward the "Tree of Beginning" to find Pikachu. What mysteries lie hidden beneath the enigmatic Tree of Beginning? Where did Mew take Pikachu? And what are the secrets behind the "Aura Legend" of the hero Aaron and Lucario?
