I've always deemed Epona to be Link's sole legitimate steed throughout the course of the Zelda franchise. She served as a great companion and cornerstone i such epics as Ocarina of Time and Twilight Princess, the former of which is my favorite Zelda game of all time. Sorry King of Red Lions and Crimson Loftwing, horse travel has been, is, and always will be the most convenient, satisfying, and adventurous way to traverse the Zelda universe.
