The King is a man with brown or purple hair and beard. I his youth, he wore a silver suit of armor with a floor-length luxurious red mantle with a white collar. His weapon was a silver longsword. In present time, his hair and beard have grown long and grayed. He wears a long red robe and a golden crown with red jewels.
Though a benevolent and kindhearted ruler for many years, even taking the orphaned Cecil and Kain under his wing, the King's demeanor has recently changed. He has ordered his people to do questionable things, such as stealing the Water Crystal from Mysidia. This change worries some of his inner circle, especially Kain and Cecil.
The King of Baron once found an infant under a tree outside Baron. As the infant reminded him of Cecilia, he named him Cecil, and raised him to be a Dark Knight. He wanted Kain to be raised likewise, but he wanted to follow in his father's footsteps to become a Dragoon. The King promoted Cecil the captain of the Red Wings due to his fealty to the Crown.
One day, Cagnazzo, the Archfiend of Water, secretly killed the King and replaced him as an impostor. While impersonating the King, Cagnazzo orders Cecil to travel to Mysidia to retrieve the Crystal of Water, and then later to deliver a package to Mist, which turns out to be a ring of bombs to destroy the town.
When Cecil abandons his post and goes on to become a Paladin, he later sneaks into Baron Castle and enters the throne room. The king is disappointed that he had become a Paladin, preferring a Dark Knight. He reveals that he is actually Cagnazzo in disguise and that he killed the real king. He battles Cecil and is defeated. Later, Cecil meets the true king, who tells him to visit the Feymarch first. If Rydia has gone to the Feymarch, he reveals himself to be the summon, Odin, and battles her to test her. The party wins, and Odin becomes a summon for Rydia.
The King of Baron is the Eidolon Odin whom Cecil summons to assist him in battle against Ceodore, Rosa, Kain, Edward and Cid, but Odin comes to his senses and acknowledges the party, and turns on Cecil.
