Sheik

Sheik is the alter ego of Princess Zelda featured in The Legend of Zelda: Ocarina of Time. Throughout the game, Sheik would appear unexpectedly and aid Link in his quest in defeating Ganondorf. Link (and the player) do not discover that Sheik is Zelda, until near the game's finale. Her appearance is very androgynous, and was made that way in order to make the reveal at the end more surprising. Because of this, she has been referred to as both male and female by other characters as well as in certain descriptions, but is canonically female.

In the Super Smash Bros. series, Sheik has been a playable fighter since in Super Smash Bros. Melee. In her first two playable appearances, using the Transform move, Zelda could become Sheik mid-battle, but in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, Sheik is a separate character.

Super Smash Bros. Melee
In Super Smash Bros. Melee, Zelda is able to use her down special move Transform to turn herself into Sheik at any point, or automatically at the start of a match by holding down A on the stage select screen, giving her a completely different moveset and playstyle. Compared to Zelda, Sheik is more agile, with quick movements and attacks, but she lacks Zelda's power. The lone exception is her up smash, which has a sweetspot that can hit twice for about 30%. Sheik is voiced by Jun Mizusawa (up until for Nintendo 3DS / Wii U), who also did the voice of her counterpart, Zelda.

Sheik's standard special move is Needle Storm, in which she gathers and tosses needles at opponents. Her side special move is Chain, in which she tosses a chain that can grab opponents. Her up special move is Vanish, in which, similar to Zelda's Farore's Wind, Sheik disappears in an explosion and reappears in a different location depending on the direction held. Finally, her down special move is Transform, which turns her back into Zelda.

According to the Star Rod's trophy information, it has most power when Sheik or Captain Falcon perform a smash attack with it.

Sheik has a victory quote exclusively in the Japanese version, "Moratta!", which is Japanese for "I got it!". As such, Sheik is the only The Legend of Zelda character to speak in the game.

Super Smash Bros. Brawl
Sheik returns in Super Smash Bros. Brawl, with the same role as before. Matching with Zelda's design, Sheik's design in this game is based on The Legend of Zelda: Twilight Princess. In this game, Sheik can now be chosen from the character select screen, by choosing Zelda and selecting Sheik's portrait. For her stage entrance, Sheik appears onto the stage, as if Zelda had just transformed into Sheik.

Sheik retains weak attacks and a powerful up smash; her down smash, however, can now hit twice, allowing for 23% damage. Many of Shiek's attacks deal less knockback, but her mobility is improved as compensation.

Sheik can now wall jump and crawl; additionally, her Chain move can be used as a tether recovery. In addition, she shares her Final Smash with Zelda, Light Arrow, though Sheik's Light Arrow deals greater damage and knocks back at a more horizontal angle than Zelda's.

Adventure Mode: The Subspace Emissary
At any point in The Subspace Emissary at which the player can control Zelda, they can transform into Sheik using the Transform move, and vice versa. However, Sheik is not properly introduced until later in the story.

After being turned into trophies and kidnapped, Peach and Zelda are being held in cages in the Halberd, until they are freed by Meta Knight, Lucario, and Snake. Snake tells them to stay where they are, but Zelda transforms into Shiek and sneaks out of the room with Peach, moving around the outside of the Halberd until they reach the main deck. While Fox is battling the Halberd in his Arwing, he almost blasts Peach, prompting Sheik to appear on top of his Arwing and attack him. Both of them leap down onto the bridge and start to fight, but Peach stops them by offering them both tea. While this is happening, Snake punches the Mr. Game & Watch copies onto the deck from the bridge, the Shadow Bugs forming together into Duon. Sheik, Fox, and Peach, along with Snake, Lucario, and Falco, fight Duon, and after it is defeated the Trophy of the actual Mr. Game & Watch appears, which Peach returns to normal. After this point, the rest of The Subspace Emissary's storyline features Zelda.

Super Smash Bros. for Nintendo 3DS / Wii U


Sheik is now a separate character from Zelda in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U. This means she and Zelda can no longer transform between each other. Instead of transforming, her down special move is now a move called Bouncing Fish, in which she leaps with a backflip and strikes with the heel of her foot. In addition, her side special has been changed to Burst Grenade, in which she tosses a small grenade attached to a string that explodes after a certain time. Like many other veteran characters in the game, Sheik's mobility has significantly improved from Brawl; on the flipside, her overall damage output is toned down to a degree.

Super Smash Bros. Ultimate
Sheik returns in Super Smash Bros. Ultimate, this time as an unlockable playable character. She has a new Final Smash, Sheikah Dance, in which she stuns any opponents in front of her (as the Sheikah symbol briefly appears) and deals multiple slashes with her knife while constantly vanishing and reappearing around them, culminating with a final blow that launches them away, similarly to Young Link and Toon Link's Triforce Slash and Cloud's Omnislash. Her outfit in this game resembles the Stealth Chest Guard and Stealth Tights from The Legend of Zelda: Breath of the Wild. As a result of Zelda's The Legend of Zelda: A Link Between Worlds-based revamps, Ayumi Fujimura now also voices her (replacing Jun Mizusawa), giving Sheik more deeper, masculine voice clips. Like her fellow The Legend of Zelda fighters, Zelda's victory theme has been changed to a new arrangement of their home series' main theme.

Like the other characters, Sheik benefits from universal changes: her already-incredible mobility is improved; her short hop timing is reduced; her aerial attacks have less landing lag; she can directionally air dodge once again; and she can use any grounded attack out of a run and any of her aerials while climbing ladders. However, her damage output receives a harsher downgrade.

Super Mario Maker
In Super Mario Maker, one of the 8-bit costumes Mario can receive from a Mystery Mushroom is Sheik, which can be unlocked either with a Sheik amiibo or by clearing 100 Mario Challenge on Normal difficulty. All of Sheik's sounds are from The Legend of Zelda: Ocarina of Time. The costume's transformation sound is the sound clip that plays when collecting an important item. Pressing will have her turn into Zelda (using her sprite in this game based on The Legend of Zelda: Twilight Princess), which briefly plays "Zelda's Lullaby" as it would sound on Link's ocarina. The sound that plays when she jumps is her voice clip when throwing a Deku Nut before disappearing. The death tune is Sheik's theme, and when clearing a level, the theme in which Link initially meets Zelda plays.

Snake's codec

 * Snake: What's going on here? What happened to Zelda?!
 * Mei Ling: Snake, Princess Zelda transformed into Sheik. I can understand the clothes, but to change her skin and eye color? That must take some powerful magic.
 * Snake: ...Magic...?
 * Mei Ling: Come on, Snake! Don't get all grumpy and start talking about how unscientific it is. Science is basically just another form of magic that makes our lives easier.
 * Snake: I never thought I'd hear that coming from you, Mei Ling.
 * Mei Ling: Don't you think talking to someone halfway around the world is a kind of magic? Or flying across entire continents?
 * Snake: No, I think this is completely different.

Palutena's Guidance

 * Pit: I wish I knew Sheik's true identity.
 * Palutena: It is one of the great mysteries of our time.
 * Viridi: Are you guys for real? You can't be serious.
 * Palutena: Compared to the other fighters, Sheik moves very quickly. Don't get overwhelmed by Sheik's speed, especially one-on-one.

amiibo

 * Sheik is a mysterious, masked warrior who played an important role in Link’s quest in The Legend of Zelda: Ocarina of Time game. Disguised as part of the Sheikah tribe that populates Hyrule, Sheik taught Link essential ocarina melodies and then vanished in an instant. Why does Sheik look so familiar?

Palutena's Guidance

 * Pit: It's Sheik!
 * Palutena: Sheik appears to be wearing a traditional Sheikah outfit this time around.
 * Viridi: Ooh! So exotic! That armor is right up my alley. I wonder if it comes in a children's small...
 * Pit: I always get nervous when Sheik gets close. If I make one wrong move, I'll get pummeled with a flurry of quick attacks!
 * Palutena: His attacks may be fast, but they aren't very strong. That's why he'll try to end the fight quickly. He's also very light, so focus on launching Sheik at lower damage percentages.
 * Viridi: And he doesn't have much reach, so keep your distance until you're ready to rush him with your Upperdash Arm.
 * Pit: Good advice! But...you guys do know Sheik is just Zelda, right? In disguise? Wait, is there a new timeline?!

Super Smash Blog bio
"Now Sheik joins the battle wearing the Sheikah costume from The Legend of Zelda: Breath of the Wild. Keep the pressure on your opponent by using his [sic] speedy dash to quickly close in on (or get away from) your opponent!"

Trivia

 * In Super Smash Bros. Melee, Sheik (along with Ganondorf and Roy) does not appear as an opponent in the game's Classic Mode, though she can appear as an ally in Team and Giant battles. As a result, her introduction image for Classic Mode goes unused. However, Sheik can be fought if the opponent is Zelda and transforms into Shiek.
 * Sheik's name can be seen in the Nintendo 64 and Game Boy Color versions of Mario Golf on the game scoreboard in Tournament mode.
 * Sheik never gets turned into a trophy in the main story of Adventure Mode: The Subspace Emissary. Likewise, Zero Suit Samus, Squirtle, and Sonic never get turned into trophies either.
 * In Super Smash Bros. Melee, Sheik ends up sending opponents flying vertically with the Home-Run Bat. Therefore, she needs to transform into Zelda to use the Home-Run Bat properly in the Home-Run Contest.
