Kaepora Gaebora

Kaepora Gaebora is the reincarnation of Skyward Sword's character and Zelda's father Gaepora. He is the first King of Hyrule, He is first seen in Ocarina of Time as an owl, serving the role as a watchful spirit like the Guardian Owl. He next appears in the form of his Terminian counterpart in Majora's Mask.

Similarities
Several similarities exist between Gaepora and his owl incarnation, including the role as the last character Link meets before embarking on his journey beyond the confines of the starting area. They both have noticeably burly builds off-set by a small head, long eyebrows that curve into a 'V" shape, Gaepra's mustache and goatee together form the shape of Kaepora's beak, and both end their sentences with "hoo-hoot!" When Kaepora Gaebora turns his head upside-down it also resembles Gaepora's round bulgy eyes. In addition, the last place Kaepora Gaebora is seen before the ending credits is atop the finger of the Sand Goddess as Link learns the Requiem of Spirit. This is relevant because the chamber inside the Goddess Statue where Gaepora alone was allowed, has a similar interior and theme to the Spirit Temple. There is one more potentially significant scene when Link learns Epona's Song and Kaepora Gaebora flies over, symbolizing the ceremonial union between rider and loftwing from Skyward Sword, over which Gaepora can be assumed to be the overseer.

In Termina
Kaepora Gaebora's counterpart in Majora's Mask varies in that he is unnamed.

Other references
Since the Owl Statues in Twilight Princess must date to around the time of Skyloft by way of their connection to City in the Sky, then it's plausible they were created by Gaepora. The kingly golden armor worn by the Hero's Shade which bears the insignia of an owl, may also be modeled after him.

Controversy
The release of the Hyrule Historia has misled some fans to incorrectly assume Kaepora Gaebora is Rauru in a transformed state. On top of the fact that Ocarina of Time contradicts this no less than six times, and his reappearance as the Light Sage in Twilight Princess which lacks Kaepora Gaebora, Shigeru Miyamoto, producer and co-writer of Ocarina of Time has referred to him as a grandfather figure created for the purposes of showing growth in Child Link."Iwata: 'More ideas sprang up than when you had just been basing the game around Adult Link.'""Miyamoto: 'Yes. When we decided to handle Link growing up from a 9-year-old child to a more mature 16-year-old, I wanted lots of characters to fulfill various roles. For example, Kaepora Gaebora is a grandfather figure who gives Link all kinds of advice and looks out for him.'"
