King Zora (Ocarina of Time)
The leader of all the Zora people, and father to the Princess Ruto. King Zora is very large in size and is often too big to do anything. He sits on his throne that guards the great Jabu-Jabu, the giant fish that the Zoras consider their God. The King is always willing to help people and it reflects in his young daughter. Freeing him from ice will grant you a Zora tunic. If you already have a Zora tunic he will offer you a kiss. Incidentally, it appears that, according to in-game dialog, King Zora and Biggoron are good friends, and have known each other for a long time.
He also appears in Oracle of Ages, where, by the time of the present, he has died because of the pollution in the sea. To save him, travel to the past and give him a life potion. After this, he will give you permission to enter Jabu Jabu if you clean the seas. He gives you the Library Key in order to help you with it.
At the end of OoT, King Zora is shown to be one of the few characters not celebrating the victory over Ganon, instead sitting next to a grieving Mido. A few theories exist on why this is:
1. Some fans of the series believe that because Ruto turned out to be the Sage of Water, that he, too, is grieving over this.
2. Some believe that King Zora sits next to Mido so as to offer him some comfort in his grief, due to him suffering from almost the same thing (mentioned above).
3. Possibly, King Zora does not join in the celebrations merely because he is too large to stand! (Knowing this, it is unknown how he actually gets over to Lon Lon Ranch).
