The Narrator delivers third-person exposition across the Pokémon animated series and films. This voice introduces the film's premise by recounting the legend of the Sea Temple crafted by the People of the Water and the Sea Crown artifact's importance. The narrative positions the Manaphy Egg as a pivotal element, pursued by both the Pokémon Ranger and adversaries.

Throughout the film, the Narrator frames the journey by contextualizing the human protagonists' alliance with the Marina Group and their mission to protect Manaphy. This includes clarifying connections between characters and locales, such as the ruins of the People of the Water and the route to Samiya.

The Narrator maintains an unwavering omniscient perspective across all media, detached from direct plot involvement. No season, film, OVA, or spin-off depicts character development, backstory, or personal growth for this role. The function remains strictly confined to introductory and concluding commentary that advances audience understanding.
