Regulus Corneas, a prominent antagonist from Re:Zero, embodies the sin of Pride to a terrifying degree. He's not just arrogant; he's convinced of his inherent rightness, viewing everyone else as beneath him. His Authority, "Stillness of an Object's Time," grants him near-invincibility, making him a formidable foe.

Beyond his power, Regulus is fascinating because of his deeply flawed and disturbing worldview. He rationalizes his actions, no matter how cruel, as necessary to protect his 'rights.' This rigid adherence to his own distorted sense of justice makes him incredibly difficult to reason with, forcing Subaru and his allies to find unconventional ways to overcome his overwhelming power. Regulus's character highlights the complexities of morality in Re:Zero, forcing viewers to confront uncomfortable truths about power, justice, and the justifications people create for their actions.
