Epona

Epona is Link's horse in Ocarina of Time and Majora's Mask. In OoT, she is raised in Lon Lon Ranch by a girl by the name of Malon and her father by the name of 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 taken by winning a race with her against Ingo 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, you find her again in Romani Ranch. Link's best friend, his trusty horse.
