Description
In the animated film Mazinkaiser vs. Great General of Darkness, Duke Gorgon serves as a minor but persistent antagonist and an operative of the Mycenae Empire. His primary mission, assigned directly by the Great General of Darkness, is to assassinate the pilot Koji Kabuto. The empire views Koji as a significant threat, specifically because he is the chosen pilot for the immensely powerful super-robot Mazinkaiser, and Gorgon is dispatched to eliminate him before he can ever take control of the machine.

True to the character's long history within the Mazinger franchise, Duke Gorgon in this film maintains a monstrous and memorable appearance. He is a centaur-like being, with the upper body of a green-skinned, armored humanoid warrior fused to the powerful lower body of a massive, yellow-furred saber-toothed tiger. Instead of replacing the tiger's head, his humanoid torso is attached to its back, leaving the snarling feline head intact and functional. He wears ancient-style Greek armor and carries a spear into combat.

His personality in this incarnation is defined by unwavering loyalty to the Mycenae cause and a tenacious dedication to his objectives. As an assassin, he is relentless, tracking Koji Kabuto across continents from a military base in Russia to Japan. He shows little regard for human life, easily dispatching soldiers and anyone who gets in his way. Despite being a formidable physical threat, his character does not undergo significant development or display complex motivations within the film’s narrative; he is defined almost entirely by his singular, driven mission to eliminate his target.

Duke Gorgon’s role in the story is that of a physical and psychological threat. He first attacks the protagonists at a military base in Russia, only for his initial attempt to be interrupted by the arrival of another Mycenae general, Ligern, who seeks glory for himself. The subsequent destruction of the base, a self-sacrificing act by a supporting character, seemingly claims Ligern, but Gorgon survives and continues his pursuit. He tracks Koji back to Japan, successfully ambushing and incapacitating Sayaka Yumi to draw him out. This sets up a final, violent confrontation.

His key relationships are hierarchical and strictly professional. He answers directly to the Great General of Darkness, whose orders he follows without question. He has a brief rivalry with General Ligern, who interferes with his mission in Russia. On the surface, his sole focus is Koji Kabuto, whom he views not as a person but as a dangerous obstacle to be eliminated. He has no meaningful alliances or personal connections with the human characters.

Regarding his abilities, Duke Gorgon is a deadly close-quarters combatant. He uses the immense speed, strength, and agility of his tiger half to pursue and overwhelm his enemies, leaping great distances and tearing through armed soldiers with ease. He wields a spear as his primary weapon. A notable and unique physical trait is that he possesses two brains: one in his humanoid head and another in his tiger head. This makes him exceptionally difficult to kill, as destroying only one brain is not enough to stop him. In his final confrontation, he survives being slammed into a gas station and engulfed in an explosion, emerging from the flames to press his attack. He is ultimately brought down when Koji Kabuto uses a ray gun to shoot him through both of his heads simultaneously, finally destroying the assassin.
