Movie
Description
The character known as Howard Lockewood is the public alias and primary disguise used by Mamo, the central antagonist of the film. Mamo is an ancient being, claiming to have been born ten thousand years ago in ancient Babylon, who has used his vast accumulation of wealth and scientific knowledge to masquerade as the world's richest man under this assumed name. His physical form is a decaying, shriveled figure, which is ultimately revealed to be just one in a long series of imperfect clones created to house his consciousness. The process involves transferring his mind into new cloned bodies, while his original, ancient physical form is preserved as a disembodied brain suspended in fluid.

Mamo's personality is defined by his cold, calculating, and deeply manipulative nature. He views himself as a superior intellectual and an arbiter of human destiny, but this grandiosity is paired with a fragile ego. He is easily provoked by defiance, particularly from the thief Lupin III, and reacts with petty jealousy and rage when he feels his desires are thwarted. This is most evident in his obsession with Fujiko Mine, whom he wishes to make immortal and rule beside him, and his vindictive treatment of Lupin when Fujiko chooses a mortal life with Lupin over eternal life with him.

Motivated by a millennia-long quest for immortality and absolute control, Mamo plans to annihilate all existing life on Earth to create a new utopia populated only by those he personally deems fit. To this end, he hires Fujiko as an intermediary to manipulate Lupin into stealing the Philosopher's Stone, which he believes will help combat the decay of his clone bodies. His role in the story is to serve as Lupin's most formidable and enigmatic adversary, a god-like figure whose schemes threaten the entire planet. He is the puppet master responsible for the film's central mysteries, including the apparent execution of Lupin in the opening scene, which was a ruse involving a clone.

Key relationships define his actions throughout the narrative. He becomes infatuated with Fujiko Mine, offering her immortality and attempting to win her affection with gestures like resurrecting extinct butterflies. His jealousy towards Lupin, for whom Fujiko shows genuine affection, drives much of the conflict, leading him to psychologically torment the thief and attempt to prove his unworthiness. His relationship with the rest of Lupin's gang is purely adversarial. He commands a network of henchmen, including his primary agent Flinch, and has a distant, instrumental relationship with the clone of Lupin he created, seeing it only as a tool that ultimately fails.

The character undergoes a significant development in the film's climax, albeit one that reinforces his core nature. After his latest clone body is destroyed, Mamo is forced to reveal his true, original form: a giant brain in a jar. Even in this vulnerable state, he remains defiant and delusional, announcing his intention to travel to another planet to achieve godhood. His end comes not from a change of heart but from his own fatal underestimation of Lupin, who plants a bomb on his escape shuttle. As he is blown up in space, Lupin delivers the final lesson that all things, including Mamo, must eventually come to an end.

Mamo's notable abilities stem from his ancient knowledge and advanced technology, which to the outside world appear as magic. His primary ability is his method of immortality through consciousness transfer into new cloned bodies. He possesses vast financial resources that allow him to operate from a fortified island headquarters and employ a private army. His technological arsenal includes advanced lasers, surveillance systems, and military hardware like helicopters and missiles. He is also a master of psychological manipulation, using gaslighting tactics such as trying to convince Lupin that he is the clone and the one who died was the original, all to serve his own jealous and egotistical ends.
