Arsène Lupin III is the grandson of Maurice Leblanc’s gentleman thief Arsène Lupin, carrying on his legacy as a globe-trotting master thief. His ethnic origins remain ambiguous across different portrayals, with conflicting hints of French and Japanese heritage, and his birthplace is often listed as unknown. He typically operates with a trusted crew that includes marksman Daisuke Jigen, swordsman Goemon Ishikawa XIII, and the femme fatale Fujiko Mine, while constantly being pursued by Interpol Inspector Koichi Zenigata. Originally depicted in the 1967 manga as a remorseless, violent criminal, his characterization in later anime adaptations evolved into a charismatic antihero who avoids killing, adheres to a moral code that includes protecting women, and often targets more violent criminals. He blends childlike exuberance with tactical genius, valuing the challenge of a heist more than possessing the stolen goods. His renowned skills include mastery of disguise, ventriloquism, lock-picking, and an array of gadgets such as grappling hooks and smoke bombs, and he favors a Walther P38 pistol. In the film Lupin the IIIrd: Fujiko Mine’s Lie, he partners with Jigen to help a young boy named Gene, who knows the location of a $500 million treasure embezzled from a mining company. Lupin doubts Fujiko’s claimed maternal concern for the boy, suspecting her usual self-interest. He adapts his strategies to counter a genetically enhanced assassin named Bincam, who wields unnatural abilities like toxin-based mind control. In Lupin the IIIrd: Jigen’s Gravestone, he wears a teal jacket and works with Jigen to steal the “Little Comet” gemstone. Their heist is interrupted by a sniper, Yael Okuzaki, who leaves a grave marker for Jigen. After Jigen appears to be killed, Lupin shifts his focus from theft to rescuing Fujiko and uncovering a government conspiracy. His relationship with Jigen deepens from pragmatic partnership to genuine friendship, and he prioritizes his allies’ safety over treasure. Across these stories, Lupin demonstrates audacity, resourcefulness, and a flair for dramatic thefts. He is trained in thievery from a young age, as shown in his youth during the 1960s, when he first met Jigen and declared his intent to become a thief independent of his grandfather’s legacy. Balancing lightheartedness with intense focus in a crisis, he enjoys fine dining, gambling, and romantic pursuits, though his success with women varies. Morally ambiguous, he may discard stolen treasures if the thrill of the heist is enough or if others need them more, and he adheres to a personal code of protecting his allies and refusing to let innocents suffer.
