Epona

Epona is Link's horse in both of the Nintendo 64 versions of Zelda, Ocarina of Time and Majora's Mask. In OoT, she is raised in Lon Lon Ranch by the girl Malon and her father Talon. The horse can be tamed by a certain song, "Epona's Song." When Epona first hears Link play this on his ocarina she is immediatly friendly with him. She can be aquired by winning a race against Ingo with her as an adult and jumping over the fence that Ingo so rudely puts there. If it wasn't for Link taming Epona when he was young, she might have been groomed for the Evil King Ganondorf to ride, which Ingo states when he says he is keeping Epona for Ganon. In MM, she is captured by Skull kid at the very beginning. She is found again in Romani Ranch.

In the upcoming Legend of Zelda game for GameCube, Link's mount is rumored to be Epona. Only time can tell what merit are in these claims.
