Lambert is a character from Lupin III: The First, serving as the film's secondary antagonist.

In the 3D CG animated film Lupin III: The First, Lambert serves as the secondary antagonist. He is a complex, bitter archaeologist tied to the remnants of the faction Ahnenerbe.

Here is a breakdown of his appearance and personality based on his depiction:

Appearance

Lambert has a distinct, elderly, and scholarly appearance that reflects both his intelligence and his rigid nature:

• Physical Features: He is an older man with sharp features, slicked-back white hair that flares slightly at the sides, a prominent pointed nose, a well-groomed white beard, and a thin mustache. He wears round, wire-rimmed spectacles. He had gold tooth.

• Attire: His wardrobe emphasizes his status as a professor and researcher. He typically wears a high-collared, long dark brown coat over a white shirt, formal trousers, and dark shoes.

• Accessories: He frequently carries a sleek, silver-handled walking cane, which adds to his sophisticated yet authoritative posture.

• In Lupin III: The First, Young Lambert appears briefly during a flashback sequence set in German-occupied France during World War II, roughly 20-30 years before the main events of the film.

  His younger design contrasts heavily with his elderly, frail appearance in the rest of the movie, highlighting his transition from a field agent to a bitter scholar:

  • Hair: Instead of his slicked-back, flared white hair and prominent white beard, young Lambert has dark, slicked-back brown hair. He is clean-shaven, completely lacking his trademark pointed mustache and goatee.

  • Facial Features: His facial features are smoother and sharper, lacking the deep wrinkles and sunken cheeks of his older self. However, he still possesses his sharp, prominent nose and piercing cerulean eyes. He does not yet wear his round, wire-rimmed spectacles in this sequence.

Profile

Lambert is an archeologist and a member of the Ahnenerbe, dedicated to uncovering ancient secrets that could empower the Third Reich. The group killed Laetitia's grandfather, famed archeologist Professor Bresson, when she was just an infant, as they were dead set on unlocking the Bresson Diary and recovering the fabled Eclipse device for their Fuhrer. Her parents later died of a fatal car crash, from which Lambert saved the then-infant Laetitia.

It is unknown if it was him who brought her to a foster home ran by nuns, but he would later adopt her when she was a little child.

Lambert was generally kind to her until she started to outshine him in brilliance and ability, which led him to be crueler and more abusive as a result of his deep insecurity and egotism. He occasionally gaslit her into believing she wasn’t smart enough to get anywhere without him, while simultaneously using her to further advance his career, such as when he plagiarized an entire essay from her thesis for Ahnenerbe. He later used Laetitia's desire to enter Boston University to make her steal the Bresson Diary, and when she failed, he'd use her again to bring Lupin III and the second key of the Bresson Diary to him. Later, he intended to slander Laetitia's name by revealing that she had attempted to steal the diary if she ever made it out, and he boasted that he was gonna be in the limelight instead of her.

Despite his Ahnenerbe membership, he never actually was loyal to the Nazis or to Adolf . Again as a result of his insecurity, he had wanted to use the now-active Eclipse to destroy Ahnenerbe's headquarters and all of Berlin, and to enact fear upon the world because of his newfound power. This enraged Gerald, who believed it should be that was to be the king of the world.

Regardless of how much he abused Laetitia, he still showed signs that he cared about her livelihood somewhat; he protested Gerald's wish to throw her out their aerial base, and he ultimately sacrificed himself to protect Laetitia from getting shot by Gerald. His last words would be him admitting he didn't know why he did that, and that he had thought she was just a useful tool.
