The Narrator features exclusively in the 2013 CGI film adaptation, delivering monologues that frame the core narrative during the opening and closing sequences. In the prologue, the Narrator describes humanity's starward expansion leading to resource depletion across colonized worlds, sparking the Homecoming War driven by a desire to return to Earth. This monologue details the rise of the Gaia Sanction government, which ended the conflict by declaring Earth a forbidden sanctuary, and introduces Captain Harlock as the immortal pirate rebelling against this regime. During the epilogue, the Narrator returns, reflecting on the story's conclusion. The monologue observes the Arcadia's escape following the revelation of Earth's true condition and the collapse of the Gaia Sanction's authority. It notes the ship's departure under new command while contemplating Earth's uncertain future—whether it will face renewed conflict or experience rebirth. Functioning solely as an external voice providing contextual background for the central conflict, the Narrator possesses no established personal identity, backstory, or character development. This narrative device does not interact with characters or influence events beyond delivering these monologues. No equivalent narrative framing device or character fulfilling this role exists within other official franchise media, including the 1978 television series, OVAs like *The Endless Odyssey*, manga volumes, or earlier films such as *Arcadia of My Youth*.
