The narrator provides expository context at key moments within the special. This voice introduces the protagonist's history as a Pokémon trainer early in the narrative, establishing his journey and capabilities prior to the main events. It also delivers essential lore about Raikou's legendary and mythological status, framing the creature's significance in the story's world before its physical appearance. The narration occurs exclusively during the introductory sequences and does not extend into ongoing commentary during subsequent plot developments. Across all related media, including spin-offs and other animated adaptations within the franchise, the narrator's role remains strictly limited to foundational exposition without personal characteristics, narrative contributions, character development, or background details.
