The character in The Legend of Zelda: Ocarina of Time that guides the main character
Link. Sheik's history is never revealed to the player, along with his face. The one other thing that is never truly revealed about Sheik is his gender. Although popular belief would have Sheik as female (and possibly even Zelda), the plot as well as the character model would state otherwise. The legend was bolstered by the production of
Nintendo's "Super Smash Bro.s" in which the player can morph between Zelda and Sheik. The creators later revealed in an interview that this was only added as a way to include the Zelda character, fearing that she alone would be too weak.
