Lord Zortek serves as the primary antagonist in Harmony Gold's English-language dub of the 1994 Gatchaman OVA, adapting the original Japanese entity Leader X. Originating from the planet Selector in the Andromeda Nebula approximately 2 million light years away, this entity was dispatched to conquer Earth and transformed a minor mafia group into the global terrorist organization Galactor. Typically appearing as a purple silhouette with a beak-like blue structure, red markings, and yellow eyes, it communicates through a circular yellow screen encased in an orange, cloudy substance resembling an eye. Its true form is a biological supercomputer composed of machinery and energy tubes, engineered by the Selector civilization. This mechanical nature enables regeneration from fragments, evidenced when a remnant evolves into the more powerful Leader Z after apparent destruction. Characterized by cruelty, manipulation, and arrogance, the entity dismisses Earth's inhabitants as insignificant obstacles and abandons subordinates like Berg Katse without hesitation. Motivated by intense hatred for human scientific endeavors—particularly the ISO's Mantle Project—it pursues planetary conquest until learning of Selector's annihilation in an interstellar war. It then shifts focus to creating a black hole at Earth's core before fleeing to investigate its homeworld's demise. Returning roughly two years later, it executes the Solar Shift Plan to eradicate humanity. Following defeat, its residual fragment regenerates as Leader Z, who recruits Count Egobossler and orchestrates the Poison Apple plan using an antimatter asteroid. Leader Z meets destruction in a final confrontation with protagonists, though ambiguity surrounds both parties' ultimate fates. The "Lord Zortek" naming applies exclusively to Harmony Gold's adaptation. Other English-language versions feature distinct names: "The Great Spirit" or "Luminous One" in Battle of the Planets, "Computor" in G-Force: Guardians of Space, and "Cybercon" in Eagle Riders. These variations reflect localization choices without altering the character's core narrative functions.
