Lúcifer is the main antagonist in the fourth Saint Seiya film, Warriors of the Final Holy Battle. His origins draw on Christian mythology: he is a fallen angel who once served his Creator but rebelled, seeking to elevate himself above God. This rebellion led to his downfall and imprisonment in the Makai, the demon world. He was eventually awakened from his eternal slumber when the spirits of the defeated gods Eris, Abel, and Poseidon fell into the demon world, granting him access to their combined cosmos.

In terms of personality, Lúcifer is defined by arrogance, sadism, vengefulness, and an insatiable lust for power. He views himself as the most perfect creature ever made and believes it is his right to unseat his Creator and rule all of existence. He is condescending toward others, including the goddess Athena and her Saints, and rarely leaves his throne, confident in his own invulnerability. His primary motivation is to become the strongest being in the universe. He seeks revenge against Athena, whom he blames for his imprisonment, and plans to drain her divine cosmos to amplify his own power. He also aims to cause global destruction as a means of forcing Athena to surrender herself.

Lúcifer’s role in the story is that of the ultimate threat. After waking, he sends four fallen angels—Beelzebub, Astaroth, Eligor, and Mois—to attack the Sanctuary. They quickly overwhelm several Gold Saints, leaving the path open for Lúcifer. He then appears at the Sanctuary before a decapitated statue of Athena and declares that he will unleash catastrophic natural disasters through the controlled cosmos of Eris, Abel, and Poseidon unless Athena offers her life. Athena agrees and goes to his Pandemonium, a dark fortress that rises in place of the Sanctuary. The Bronze Saints fight through the fallen angels to reach her. Lúcifer attempts to use Athena as a living battery, with thorny vines that drain her cosmos and transfer it to the other gods. When Seiya finally reaches him, Lúcifer is momentarily blinded by the combined light of the twelve Gold Cloths, allowing Seiya to strike with the Sagittarius golden arrow and defeat him.

Key relationships include his deep enmity with Athena, whom he sees as both a rival and a tool for his ascension. He manipulates the defeated spirits of Eris, Abel, and Poseidon, using them as pawns to cause destruction and to pressure Athena. He commands four powerful fallen angels who act as his lieutenants. He also references past conflicts with the archangel Michael and the war deity Marishi-Ten, though these are not elaborated in the film.

Lúcifer undergoes no significant character development; he remains consistently megalomaniacal and convinced of his own supremacy until his defeat. His defeat is brought about not by a change in his nature but by the Saints’ determination and the miraculous resonance of the Gold Cloths.

His notable abilities are formidable. He can manipulate the cosmos of other gods to trigger planetary-scale disasters—hurricanes, earthquakes, floods, and volcanic eruptions. He fires a powerful energy beam from his index finger, capable of decapitating the giant statue of Athena with a single shot. Within his Pandemonium, anyone who enters is assaulted by bursts of energy; this may be a property of the location or Lúcifer’s own power. The fortress is also filled with living thorny vines that drain the life force and cosmos of anyone they ensnare. Lúcifer’s throne is shaped like a seven-headed dragon, and he is physically protected by his own immense divine cosmos. Despite his power, he is ultimately vulnerable to attacks empowered by the combined light of the twelve Gold Cloths, which momentarily blinds and disorients him.
