King Sword is a villain from the video game Final Fantasy Legend, he is a king who acts as the second boss of the game, not much is revealed about his personality or goals - although some characters warned the heroes that the King was evil, suggesting he had a fearsome reputation: he rules over his own castle and informs the heroes who arrive that they must defeat him in battle if they seek his sword. Since their quest dictates that they must retrieve this sword the heroes accept his challenge and presumably slay him, taking his sword as a result.
