In the legendary past, before the creation of Poké Balls, an aura-guiding hero Pokémon named Lucario sensed two armies about to clash at Cameron Palace in Kanto. He told his master, Sir Aaron, while he was being attacked by a group of Houndoom. During the battle, Lucario was blinded, and he used his Aura Sphere to eliminate the Houndoom.
