Cesare Borgia is a prominent antagonist from the Eastern Star who serves as a key member of King Arthur’s Round Table. He is a young man with a striking appearance, characterized by his long orange hair tied in a ponytail, pink eyes, and a cape trimmed with fur. As a commander from the Western Star, he leads his own forces in the war against the opposing planet.

Initially, Cesare is defined by his ruthless ambition and duplicitous nature. He is a skilled strategist and fighter, but his methods are frequently underhanded and dishonorable. He demonstrates a willingness to betray his own allies without hesitation to achieve his goals, showing no qualms about backstabbing fellow members of the Round Table. This cunning and treacherous behavior, combined with a charming and polite demeanor, makes him a formidable and unpredictable foe. He is known for his iconic Latin phrase, often mispronounced for dramatic effect, adding a layer of theatrical arrogance to his persona.

A primary driving force for Cesare is his obsessive infatuation with Ichihime, the sister of his rival, Oda Nobunaga. This obsession leads him to commit brutal acts, including the murder of Ichihime’s father in an attempt to claim her. His actions are often calculated to corner Nobunaga, such as proposing a false alliance specifically to take Ichihime as his wife. Despite his villainous nature, his feelings for her are portrayed as genuine, and this attachment complicates his character, serving as a catalyst for his eventual change of heart.

Throughout the story, Cesare serves as a major obstacle for the protagonist, Oda Nobunaga. He is responsible for the capture and physical torture of the seer Jeanne d’Arc, and his military campaigns constantly pressure Nobunaga’s forces. His role shifts dramatically when he becomes disillusioned with King Arthur’s true plan. After realizing Arthur intends to consume the world, Cesare betrays his king and risks his own life to save Nobunaga and his allies, driven by his desire to protect Ichihime. Later, he falls under King Arthur’s mind control, becoming a puppet who speaks of peace and universal love, a stark contrast to his original personality. In this state, he is a tragic figure, still obsessed with possessing Ichihime, but no longer in control of his own will.

Cesare’s most significant relationships are with Oda Nobunaga and Ichihime. He is a rival and foil to Nobunaga, viewing him as a coward while employing tactics Nobunaga would consider disgraceful. His bond with Ichihime is his greatest weakness and his only path to redemption. His relationship with his king, Arthur, is one of subservience that eventually turns to rebellion. Cesare’s development is a major arc, transforming him from a hated villain into a tragic anti-villain who ultimately sides with the protagonists. His death comes while fighting against the control of Arthur, killing several of Arthur’s minions and dying alongside Ichihime, cementing his complex legacy as a man undone by his own passions.

As a warrior, Cesare wields the legendary sword Excalibur and is a highly capable combatant, able to pilot a Regalia, the giant war armors used in the series’ battles. He is also a competent leader and strategist, though his penchant for espionage and backstabbing sets him apart from more honorable opponents. His defining trait in battle is his sheer willpower, which allows him to overcome seemingly impossible odds.
