He informs that Link must awaken the seven sages in order to bring peace back to Hyrule. Alerting him of the need to possess a new tool in order to enter the temples he then disappears, later reappearing when Link arrives at the Sacred Forest Meadow. He tells Link about the warp songs used to teleport to temple entrances and teaches him the Minuet of Forest before disappearing again. Further along Sheik approaches Link at the Fire Temple entrance in the Death Mountain Crater, teaching him the Bolero of Fire before walking away, using a wall of flame to halt Link's inquiring advance.

Sheik once again mysteriously appears in the Ice Cavern to inform Link of the fate of the Zoras and to teach him the Serenade of Water. He then awaits outside the Water Temple for Link to free the temple and awaken the Water Temple sage before disappearing once again. When Kakariko Village comes under attack from a mysterious force Link discovers that Sheik is already there and together they encounter, and are defeated by, an invisible monster thought to be the Shadow Spirit. Sheik teaches Link the Nocturne of Shadow and urges Link to help Impa fight the Shadow Spirit. When Link discovers that he must venture back in time in order to do so Sheik offers a helping hand, informing him on how to use the Master Sword and the Pedestal of Time in order to travel back and forth through time. He teaches Link the Prelude of Light then once again vanishes.

At the entrance of the Spirit Temple Sheik appears, having being waiting for Link from atop a large rock formation, and once again informs Link that he must enter the temple as a child, utilizing the Pedestal of Time in the Temple of Time. He gives Link a lesson on performing the Requiem of Spirit before using the desert winds as cover to vanish.

With all six sages freed Link is instructed to return to the Temple of Time where none other than Sheik awaits. Sheik congratulates Link on his efforts and offers an explaination on what exactly happened to Hyrule during Link's disappearance before finally revealing her true identity, as Princess Zelda

Super Smash Bros. Melee
In Super Smash Bros. Melee Zelda has the option of transforming into Sheik. To do this, you must press down the analog stick with the B button. Sheik has a completely different moveset than Zelda. Sheik's moves and weapons are quick and similar to those of a ninja. Sheik is an extremely speedy character and for this reason she could be a bit difficult to control. Although she has an original moveset, she is found to have similarities with Captain Falcon. In Melee the two of them have a more powerful star rod attack. In the game, Sheik is always referred to as a female.

Super Smash Bros. Brawl
Sheik has been confirmed for the sequel to Super Smash Bros. Melee, Super Smash Bros. Brawl. Although she did not appear in The Legend of Zelda: Twilight Princess, the character model was based on a design drafted during the game's development. She has mostly the same moveset from Melee, and shares a Final Smash with Zelda, the Light Arrows.

Ocarina of Time manga
Sheik first appears to Link having tended his wounds after being defeated by Volvagia. Sheik is a spy for Ganondorf, and later shows up to tell Link a rumor that Princess Zelda had been spotted in the Desert of Illusions, before vanishing again. On Link's way through the Desert, he nearly succumbs to blistering sands before Sheik pulls him out, and continues to travel with him. Later that night, Link is be attacked by illusions and images of his past, but Sheik is unaffected; Link wonders if it is could be due to a lack of past in Sheik's life. Once reaching the Gerudo Fortress, Sheik knocks Link out, and the Hero is captured.

Once Link frees himself, he fights through the ranks of Gerudo, before Sheik comes to him with his sword and shield. Throwing them to Link, Sheik turns on the invisible Twinrova, who were watching nearby. They are enraged as Sheik explains to have always been on Link's side, and attack.

After escaping with the unconscious Sheik, Link finds a cave to rest in. He leaves to find water, flustered after getting too close to Sheik. He returns to find that Sheik, having awoken with the face wrappings off, appears to be female. Fully transforming, Sheik is revealed to be Zelda, who later explains that she had Impa lock her conciousness away, and assume the guise of a Sheikah boy.

Gender Issues
As Sheik spends most of the latter part of the game disguised as a male, many fans have argued to Sheik's true identity. There is no hint given in the game that Sheik is in fact a male; however, at one point Ruto refers to Sheik as a "he". This is most likely explained by Ruto being unaware of Sheik's true nature. However, Sheik's build, proportions, and facial structure are more suggestive of a male

Various theories to Sheik's true gender exists, but few offical statements have been released clarifying if Sheik is male or female. In the Ocarina of Time manga, which deviates from canon, Princess Zelda had, instead, sealed away her conciousness and transformed herself into the Sheikah male, Sheik. However, in Super Smash Bros. Melee, Sheik is referred to as a "she", as well as the character summary of Sheik on the official website.
