As the absolute ruler of the ice-covered planet La Metal, Leader Larela commands a subterranean humanoid species called La Metalians. Her appearance varies across adaptations: the 1982 film presents her as a small, ghostly child with a glowing body, blank iris-less eyes resembling a mask, and levitation-enabling energy halos above her head and beneath her feet. The manga depicts similar halo-like objects but renders her as a human-like child floating without leg movement. In Space Symphonic Poem Maetel, she retains a childlike form with distinctive white hair and black eyes, often utilizing a floating mechanical chair for mobility. Larela's core motivation arises from La Metal's catastrophic 1,000-year orbital cycle that brings the planet near Earth, threatening humanity's extinction. As Holy Queen, she orchestrates Earth's colonization by abducting and enslaving its population, dispatching operatives like her daughter Andromeda Promethium (Yukino Yayoi). She scorns humans as "primates" unworthy of Earth's paradise, rationalizing genocide as essential for her species' survival during their frigid and endless spaceflight. Her personality exhibits ruthlessness, intolerance for defiance, and a godlike conviction in her right to control universal life. In the film's climax, Larela confronts Promethium over her betrayal, attacks her for sympathizing with humanity, and orders her mind altered by machine. Hajime Amamori thwarts this by shooting her subordinate Fara. Weakened, Larela is critically wounded by Promethium and further incapacitated when Fara destroys her levitation halos. She perishes when confronted by spirits of past Millennial Queens. The manga expands her backstory as "Larla," a million-year-old La Metal director manipulating events remotely via holograms. She demonstrates telekinesis and deceptive bargains, like offering Hajime luxuries for freedom. Her control extends to an "Ancient Conspiracy" influencing Earth since the Cambrian Period, with prior Millennial Queens including figures like Cleopatra. In Space Symphonic Poem Maetel, Larela shifts toward ambiguous mentorship. After subjecting Maetel (Promethium's daughter) to psychological tests—virtual assassins and a simulation forcing her to kill Promethium—Larela aids her by revealing La Metal's secret core planet. Recognizing Maetel's resolve to end hatred cycles, Larela sacrifices herself in La Metal's organic energy conversion system, activating gravitational controls to separate the inner planet and destroy Promethium's imperial legacy.
