Lupin the Third: The Mystery of Mamo

Lupin faked his death at Castle Dracula by using a decoy body. Inspector Zenigata traveled to Transylvania to confirm Lupin's demise, but the body was a ruse that allowed Lupin to slip away unnoticed and continue his criminal pursuits.

Fujiko betrayed Lupin in Paris by stealing the Philosopher's Stone for a mysterious client whose identity is never fully revealed. Her ambiguous loyalties and personal agenda drove her to double-cross the team, setting in motion a chain of events that affected the entire story.

Lupin himself engineered the fake Philosopher's Stone as a clever deception. When Mamo discovered it was fake, he used that discovery to tighten his control over Lupin and his team, revealing that the entire scheme was designed to trap and reveal betrayals within Lupin's circle.

Mamo is the true antagonist who operates under the alias Howard Lockewood, presenting himself as a wealthy, omniscient patron. He is actually a ten-thousand-year-old mastermind who has survived through cloning, using his vast resources and multiple identities to orchestrate global schemes.

Yes, Mamo reveals in Colombia that he has cloned Lupin III as part of his experiments spanning thousands of years. He explains that he has been seeding conflicts across different eras through cloning, making Lupin himself one of his 'experiments' and turning the threat into a personal mockery.

Mamo achieved immortality through a sophisticated cloning technique that allowed him to transfer his consciousness across multiple cloned bodies over ten thousand years. His original form was revealed to be a giant brain contained within a rocket, with all his physical manifestations being clones.

Mamo planned to repopulate the Earth through a calculated nuclear threat. He launched nuclear missiles while intending to force Fujiko to embrace his version of immortality, which would erase the line between creator and creation. The plan involved destroying humanity to start anew with selected survivors.

After learning that the Lupin case was part of a much larger conspiracy involving Mamo's global operations, the ICPO chief told Zenigata he was off the case. This admission of a wider conspiracy prompted Zenigata to resign and continue chasing Lupin as a private citizen, driven by his personal sense of duty.

During the climactic duel with Flinch on Mamo's Caribbean island, Goemon lost his legendary sword Zantetsuken. The sword was damaged in the fight, prompting Goemon to leave and train to recover its edge. He later uses the sword tip to help Lupin defeat Mamo.

The giant brain contained in the rocket was the original Mamo, his true form after thousands of years. Lupin realized that Mamo's power resided in his clones all along, not in any single physical body. The brain was jettisoned toward the sun as Lupin rigged an explosive to prevent catastrophe.

Lupin escaped during the USAF bombardment of Mamo's Caribbean base. Jigen rescued him and Fujiko in a dramatic escape. Later, in the temple fortress in Colombia, Lupin sabotaged the missiles by rigging them to explode before launch, and used the tip of Goemon's sword to deflect Mamo's lasers and incinerate him.

In the temple chamber, Mamo pressed Fujiko to embrace his immortality plan and abandon humanity. However, Fujiko refused to abandon Lupin, choosing to stay with him despite the dangers. This moment crystallized the unstable but genuine bond between them.

After escaping the rocket explosion, Lupin was briefly captured by Zenigata who finally closed the net. However, their chase ended in a stalemate - both men escaped with their ankles shackled together, continuing their endless game of cat-and-mouse. Fujiko was rescued by Jigen, and Goemon delivered the closing fourth-wall-breaking line.
