Nero is the Phoenix Knight in the animated series Knights of the Zodiac, a reimagining of the original Saint Seiya story. He serves as a rogue Bronze Knight initially aligned with the antagonist Vander Guraad, acting as a formidable opponent to Athena and her protectors. Nero is the older brother of Andromeda Shaun, and their bond is a central aspect of his character. In his youth, he was described as fierce and tough yet kind, and he trained his younger sister to defend herself. However, after training on Death Queen Island to become the Bronze Knight of the Phoenix constellation, his path took a darker turn. Physically, Nero is a muscular young man with tan skin, navy blue hair, and silvery blue eyes, giving him an imposing presence. His personality is marked by volatility and a rogue nature, often bringing him into conflict with other knights. When he fights, his Cosmo manifests as a burning aura, and his signature technique is Phoenix Rising. Nero’s motivations are initially tied to his allegiance with Guraad, but his development involves a gradual shift as his relationship with Shaun and his own sense of honor come into play. Over the course of the story, Nero undergoes significant change, moving from an antagonist to a figure who questions his loyalties and eventually reconnects with his sister, contributing to the larger battle to protect Athena.
