Lupin the Third | Part 1 | Movie(s) Fan Dub

In the original anime Goemon's relationship to Lupin starts off more professional than close friendship. By the second anime series, Goemon has developed a true loyalty to Lupin. However, he easily gets annoyed by Lupin's antics, especially Lupin's infatuation with women, Fujiko Mine in particular. He will occasionally oppose Lupin directly when Lupin's jobs or actions do not agree with his morals. He has even promised that the last act he will take with Lupin is delivering his deathblow. However, Goemon doesn't hesitate to help Lupin in serious situations, and readily assists him any time Lupin works for a just cause. However, in 1978's The Mystery of Mamo, he claims that he helps Lupin simply so he can keep his vow to kill him himself.

Young Adult - Middle Age 

In Monkey Punch's original manga, Lupin is cocky, quite crude, and for the most part remorseless. He is very much the ladies' man, often using them for his own gains, but is not beyond forcing himself upon women who resist him. This is in stark contrast to his better-known anime self, who despite being a skilled thief, comes off as a goofball and will go to great lengths to right injustice, who also shows a chivalrous streak that compels him to help those less fortunate than he. Furthermore, Lupin often takes it upon himself and his gang to stop criminals engaged in more violent crimes and leave them for Zenigata to arrest. In the anime, while he fancies himself a Cassanova, his actual success with women is erratic, appearing to fluctuate with the writer.

Daisuke Jigen is the trigger man, sharpshooter, aide-de-camp and close friend of Arsène Lupin III. Along with colleague Goemon Ishikawa XIII, he joins Lupin in pursuit of riches acquired typically by theft. Traveling across the globe, Jigen has garnered fame as a gunman with a wildly capable speed and accuracy.

Inspector Zenigata hails from Japan, city of origin unknown. According to Episode 0: First Contact, his original title was Tokyo Police Inspector whose original interest was the capture of Fujiko Mine and her then partner. His pursuit took him to New York where he met Arsene Lupin III for the first time. He left the Japanese Police Force in favor of enlisting in ICPO (Interpol) for the sake of specifically bringing Lupin to justice. For a brief period between the first and second TV series, Zenigata was demoted to a beat cop in an unknown location of Japan. 

Zenigata has made it his life's mission to arrest Lupin. The other members of Lupin's gang are targeted for apprehension as well, but Zenigata usually ignores them when Lupin himself is present. Lupin and Zenigata appear to be the worst of enemies, but in the anime they are, in a manner of speaking, friends; something Lupin shows openly (often by greeting Zenigata with mock affection), but it is an idea Zenigata is extremely reluctant to entertain. Similarly, he is often awed by Lupin's genius. Zenigata has an attachment to Lupin with the belief that no one should kill him or worse, capture him, besides Zenigata himself.

While Fujiko is not part of Lupin's gang, she often participates in their exploits either as a partner or a competitor. Her principle tactic is to stick with Lupin and company until the plunder is made available then double-cross her colleagues. Frequently, she finds it necessary to betray Lupin to get close to the enemy, then after ingratiating herself into his trust will acquire the swag and escape (rarely, she will help to extricate Lupin, Goemon and Jigen for the trouble she put them into, as if to atone). Fujiko is also known to provide Zenigata or other law enforcement officers with information and assistance in order to gain her own freedom . At one point, Fujiko was made Zenigata's replacement on the ICPO's Lupin operation, however this was a cover for her to get into a secret vault.

Of this two-faced nature Lupin is surprisingly forgiving. In the 1995 movie Die! Nostradamus, Lupin carefully treats the amnesiatic Fujiko, hoping she gets better as he "looks forward to her betrayals".
