Biography
When the forces of Zant invaded Hyrule, Zora's Domain was frozen over and the Zoras were trapped. At the behest of his mother, Ralis set out for Hyrule Castle, to alert Princess Zelda about the situation, and ask for her help. Zant's forces attacked him en route, however, and he was rescued by Ilia. He became ill because he had been away from the water for too long. He was taken to Telma's Bar, where even Doctor Borville was unable to assist him. Later, Link arrived and transported the Prince to Kakariko Village, to be treated by Renado.

Upon returning to Zora's Domain, Prince Ralis was reluctant to become the King Zora, but resolved these feelings with Link's help.

Prince Ralis is an excellent Reekfish angler and provides Link with the Coral Earring, which is the lure required to catch a Reekfish. This is required in order to proceed to Snowpeak. During the ending credits, Ralis is seen sitting on top of the cliff in Zora's Domain and being watched over by the spirit of his mother.
