Prince Saphir is a member of the Black Moon Clan. He is the younger brother of Prince Demande. Saphir harbours misgivings about his older brother's ambitions but still supports him. He likes Droids because they don't stray away from plans, and will never betray him.
Saphir is depicted as a young-looking man with dark blue hair, dark blue eyes, fairly pale skin, with a black, upside-down crescent moon on his forehead. He wears a dark blue jacket with ornaments, that are stainless steel and rod-shaped. He also wears white pants, white shoes, and dark blue gloves.
Saphir invented the black crystal earrings but he does not wear them, until the upgraded version are forced upon him.
Saphir was destroyed by his older brother Prince Diamond using the Invincible evil sight.
