The Narrator features solely in the film's prologue sequence. This opening segment unveils the historical origins of Alto Mare and recounts the pivotal events surrounding its guardian Pokémon. Through this narration, audiences learn how an ancient Latios gave its life to shield the city from an evil Pokémon Trainer commanding Kabutops and Aerodactyl. This sacrifice reshaped Alto Mare's streets into canals and forged the Soul Dew, containing the essence of the fallen Latios. The Soul Dew then empowered Alto Mare's hidden Defense Mechanism, a safeguard kept secret to prevent exploitation. The Narrator's account establishes the Soul Dew's vital importance and introduces the continuing protective duty of the original Latios's offspring, Latias and Latios, as the city's guardians. This prologue delivers essential context for the film's core conflict, though it was removed from international releases. The Narrator makes no further appearances or receives any development elsewhere in the film or related media.
