Daphnes Nohansen Hyrule

King Daphnes Nohansen Hyrule is the King of Hyrule, a character which makes few appearances. In fact he only appears in two games with the first being A Link to the Past in the ending credits. In his second game, The Legend of Zelda: The Wind Waker, he had a more key role. Strangely enough there is no mention of a Queen.

A Link to the Past
According to the manual The King became deceived by the wizard Agahnim. After completing the game you are shown the cast members including the King.

The Wind Waker
A character from The Legend of Zelda: The Wind Waker. He was the King of Hyrule at the time of the Flood outlined in the game's prologue. Daphnes is the man beyond the King of Red Lions, remotely operating it from his resting place at Hyrule Castle. After you defeat the Giant Bird, you will be shown at the Tower of the Gods and be sent back down to the castle under the sea, this time with the pirate, Tetra. Head down to where you got the Master Sword with Tetra and there you'll meet Daphes himself. He will tell you that he is the King of Red Lions and after he's done with his long speech, he will ask Tetra for the pendant around her neck. He will also take out a pendant from his robe and combine the two together, thus transforming Tetra into Zelda!!! After this he will ask you to regain the power of your triforce and reawaken the sages of the Master Sword. When you have finally met Ganon, he will take you and obtain your triforce as well as Zelda's, thus completing the Triforce. Ganon is about to touch it and obtain full power, da da daaaaaaaaaaa, Daphes comes to save the day! He touches the Triforce first and makes it that you and Zelda have the power to defeat Ganon. Once you beat Ganon to a pulp and water starts to fill up around the castle, Zelda tells Daphnes to go back to the surface. She wants to find a land to create a new Hyrule. The king refuses, saying that the kingdom of Hyrule belongs to the past, and the children must have a future. As Link and Zelda raise toward the surface, the king stays with his doomed kingdom, and dies.
