Description
La Frankenbach Leopard, also known as Leopard Error Franken-bach, is a character from the anime Queen Millennia. He serves as the commanding officer of La Metal, the planet that is on a collision course with Earth. His background is that of a high-ranking military official and a highly skilled scientist and inventor, responsible for creating advanced technological marvels used in space travel and exploration.

In terms of personality, La Frankenbach Leopard is cold, calculating, and highly analytical. He approaches problems with a strategic mindset and is deeply logical, often appearing ruthless in pursuit of his goals. He is initially depicted as a loyal and unquestioning soldier to the Millennial Queen and to the Holy Queen Larela, fully committed to the mission of La Metal. His primary motivation early in the story is to serve his superiors and carry out the plan to secure a future for his home planet, even if that plan involves the subjugation or conversion of humanity.

However, a key aspect of his character is a gradual internal conflict. As the story progresses, he begins to realize that he still retains a sense of humanity. This realization causes a significant shift in his role. He ultimately betrays the Promethium II, also known as the Millennial Queen, and her plan to convert all of mankind into cyborgs. He joins forces with Maetel, Nazca, Emeraldas, and Harlock, turning against his former allies to help save humanity.

His key relationships are defined by his loyalty and eventual betrayal. He is initially subservient to the Millennial Queen and Holy Queen Larela. He has a complex connection with Seren, the younger sister of Yayoi, as he once served as her instructor and cared for her before she was abandoned by her mother. His relationship with Yayoi, the current Millennial Queen, is also significant, as he is ordered to investigate her and later attempts to kill her sister, leading to his own death at Yayoi's hands.

His development is marked by a journey from a loyal, ruthless antagonist to a redeemed figure who sacrifices himself. In one version of his death, he is shot and killed by a half-dead cyborg while being praised by the people he saved, managing to destroy the cyborg before falling. In another, he is killed by Yayoi when he tries to kill Seren. His notable abilities include his strategic command skills, his scientific and inventive brilliance, and his prowess as a combatant. He is a formidable opponent, using his intelligence and technological resources to challenge the heroes of the series.
