Mayor Bo

Mayor Bo (ボウ, Bō) is the mayor of Ordon Village and father of Ilia. He is first seen in very beginning of the game, found in front of the mayor's house by the road that leads up to Ordon Ranch. If Link speaks to him on his second or third day, it will trigger a sequence where a goat will come rushing down the road, and Link will have to wrestle it to the side in order to stop it.

Bo becomes instrumental to the Twilight Princess plot as Link reaches the base of Death Mountain after freeing the Light Spirit Eldin from its Twilight bindings in Kakariko Village. The Gorons on Death Mountain are far too brawny for Link to face unaided, for he does not possess enough physical strength to match that of a Goron. Bo teaches Link the secrets of the art of sumo wrestling in his home, and tells him that he defeated the Goron patriarch in his day with a secret: the use of the Iron Boots. As a gift, he gives the boots to Link, which ultimately helps him defeat Gor Coron, a Goron elder, in a sumo wrestling match up on Death Mountain, allowing him entrance into the Goron Mines. Later, when Link speaks to Gor Coron, he will say that it is fortunate that Ilia looks more like her mother instead of Bo.

Trivia
Bo and Ilia share many similarities with Talon and Malon, two recurring characters from the Zelda series. As another father/daughter relationship, they both live in proximilty to a farm and live very sedentary lives. Personally, Bo boasts facial hair reminiscient of Talon, and Ilia's love for Epona strongly connects her to Talon's daughter, Malon.
