Regulus Corneas is the Sin Archbishop of Greed in Re:Zero - Starting Life in Another World, a Japanese light novel and anime series centred on Subaru Natsuki. Regulus is known for his extreme arrogance, his insistence that he is always right, and his terrifying power in battle, which makes his calm introductions feel especially unsettling. Unlike Subaru's Return by Death, which resets time after failure, Regulus presents himself as someone who never needs a second chance. Fans reuse his introduction online to signal a self-important villain, especially in edits, rankings and reaction videos.
