Fujiko Mine operates as a professional criminal, burglar, and confidence trickster, working both solo and alongside Lupin III's gang. She specializes in theft, espionage, and seduction, frequently leveraging her physical allure to manipulate targets. Her dynamic with Lupin III blends cooperation and betrayal; she often joins his heists as a partner or rival only to double-cross him and seize the loot. Despite her betrayals, Lupin remains infatuated, readily forgiving her and sometimes risking himself to aid her. She is not a permanent team member.
Her past includes ties to organized crime through a partnership with the assassin "Killer Poon." Known as "the Golden Couple," they performed contract killings for a syndicate until Fujiko was marked for death. Poon failed the kill due to emotional attachment, leading Fujiko to vanish and later claim amnesia about this period. Franchise continuity reinterprets this backstory.
Fujiko excels in combat and infiltration. She is an expert markswoman, typically concealing a Browning M1910 pistol in her garter. Proficient in martial arts, she disables larger opponents with precise strikes. Her mastery of disguise extends to mimicking accents and speaking multiple languages. She skillfully operates various land, sea, and air vehicles, favoring a Kawasaki motorcycle. Her strategies often involve seduction and sexual relationships to gather intelligence or create escape routes, with her sexuality depicted as fluid, implying bisexuality in some narratives.
In "Lupin III vs. Detective Conan: The Movie," antagonists force an explosive collar onto Fujiko's neck, threatening detonation unless Lupin steals the "Cherry Sapphire." This coercion drives Lupin's actions. Fujiko later escapes captivity and pilots a submarine to rescue Conan Edogawa and Lupin during the climax. Her role concludes with ambiguous scientific curiosity about Conan's altered physiology.
Her appearance varies significantly across media, featuring different hair colors (brunette, blonde, red) and lengths. Consistent features include brown eyes and a preference for fashionable, figure-accentuating clothing like formal gowns or functional outfits such as a catsuit inspired by "Girl on a Motorcycle."
Fujiko shares dynamic relationships: Daisuke Jigen distrusts her as a complication but sometimes defends her; Goemon Ishikawa XIII maintains wary ambivalence despite a past romance; Inspector Koichi Zenigata engages transactionally, exchanging information or assistance for immunity, including one instance of a sexual arrangement.
Her motivations center on financial gain, thrill-seeking, and preserving autonomy. She enjoys luxury pastimes like shopping, disco dancing, and sipping champagne or martinis. Fears include claustrophobia, aging, and a specific aversion to frogs. While self-serving, she occasionally shows concern for children and has expressed deeper, rarely acknowledged emotional attachment to Lupin during crises.
