Dark Link

Dark Link, also known as Shadow Link or Link's Shadow, is an evil version of Link first appearing in The Adventure of Link and is one of the most popular enemy characters in the The Legend of Zelda universe, mostly due to his likeness and ability matching that of the protagonist, Link. It has been speculated that his popularity is so great in part because he imitates almost every move Link makes, as if Link is fighting himself rather than a separate entity; that is, Link and Dark Link are opposite in intentions, but perfectly matched in ability as well as action.

Attributes of the Dark Links
As the doppelgänger of Link, in all of his appearances, Dark Link bears resemblance to Link in whichever game they're in and wears the same style clothing as him: tunic and a long, floppy cap, with the exception of his entire outfit being black or dark gray instead of green. Moreover, his hair is usually either a shadow black or a dark gray. The majority of the Dark Links are left-handed, but in some appearances (particularly when there was more than one), they have been shown to favor either hand. Another notable feature aside from the color scheme of his clothes is Dark Link's red eyes, which are usually the only prominent feature against his dark visage.

Soundtracks/Themes
During his many appearances, Dark Link has had different soundtracks played to commemorate the moment of his presence. The names of the soundtracks/themes are as follows:

The Adventure of Link: Boss Battle Ocarina of Time: Middle Boss Battle Four Swords Adventures: Shadow Link, Boss Battle Twilight Princess: The Dark Interlopers Spirit Tracks: Ghost Ship Bellum Battle

The Adventure of Link
In his first appearance in the series, Dark Link is known as Link's Shadow and appears as the final boss in the game. He serves as the final test before Link can obtain the Triforce of Courage and wake Princess Zelda. Dark Link is the most difficult opponent to appear during Link's second quest to save Hyrule. In battle he dodges most of the attacks that Link attempts but is vulnerable when he jumps. This flaw can be taken advantage of by simply standing in a corner and repeatedly swinging Link's sword toward Dark Link. Dark Link will attempt to jump at Link and keep running into the attacks, making a rather difficult battle seem less difficult.

Ocarina of Time
In Ocarina of Time, Dark Link appears as a mini-boss in the Water Temple, where he materializes from a dead tree to confront his good counterpart. Dark Link mirrors most of Link's movements and attacks, usually defending himself in the process. He also possesses the ability to disappear and spring up from the floor after being hit.

To defeat him, Link must use the Megaton Hammer, the Deku Nuts, or the Biggoron Sword, or by using  his sword and while L/Z targeting him do a horizontal slash on the opposite side of his shield, which gives Link an instant hit. Stocking up on magic potions and using Din's Fire is another option that makes the fight against Dark Link very easy. However, once enough time passes, he will fight on his own, countering every sword attack. Din's Fire is the best option in this part of the battle. If Link performs a sword lunge or the thrust, as Dark Link will simply jump up and stand on the blade before attacking. Once Dark Link is defeated, Link is able to continue on to a room containing the Longshot.

Dark Link shares Link's voice, but it is heavily distorted, giving it a demonic feel. At the beginning of the battle, Dark Link is nearly transparent, but will gradually become opaque as the battle progresses.

Oracle of Ages
During the second phase of the final battle, Veran creates 4 red-eyed copies of Link that moved opposite of him as obstacles. These Shadow Links do not attack, however, and are useful in recovering health, as each one drops one heart each. They are also compared to Arm-Mimics and Mask-Mimics.

A Link to the Past/Four Swords
On the Game Boy Advance port, after completing both A Link to the Past and the multiplayer Four Swords game, the Palace of the Four Sword is unlocked. The Dungeon Master is four Shadow Links, each with a unique tunic, corresponding to the colors of the Links that hold the Four Sword. Each Shadow Link has slightly different abilities, but they all aggressively attack with sword swipes and do not open their defenses often. They are quite agile, able to leap backwards out of the way of Link's attacks. They get progressively difficult. The Green Shadow Link uses the Pegasus Boots to suddenly dash at Link, the Red Shadow Link uses the Hurricane Spin and the Pegasus Boots. The Blue Shadow Link also uses Pegasus Boots, the Hurricane Blade, and he can leap into the air to perform a Down Thrust (which is similar to Link's use of the Quake Medallion). The Purple Shadow Link is the final, and utilizes the Pegasus boots, Hurricane Spin, Down Thrust, and the Sword Beam.

Four Swords Adventures
In Four Swords Adventures, Dark Link is referred to as Shadow Link and is featured as both a main character and a recurring boss. Shadow Link had been brought forth by the stolen Dark Mirror and he tricks Link into drawing the Four Sword, releasing the ancient wizard Vaati and splitting Link into four Links. He then produces copies of himself and plagues Hyrule by attacking its citizens, who blame the Links for his misdeeds. Dark Link shows up twice in each stage, where whoever managed to kill him could receive 100 Force Gems. He is also a boss for the Cave of No Return, Village of the Blue Maiden, Desert Temple and The Dark Cloud stages - where, during each battle except for the Dark Cloud stage, he would eventually take on a color, and only the corresponding Link could damage him.

Shadow Link and his kin are defeated in The Dark Cloud stage when, while the Links engage them in combat, Princess Zelda undoes the seal on the Dark Mirror and takes it into her possession, dispelling them.



Twilight Princess
Dark Link makes a cameo appearance during a cut-scene in Twilight Princess that tells the tale of how the Twili race was banished to the Twilight Realm. Portraying the powerful Dark Interlopers who sought to control the Sacred Realm, Dark Link manages to destroy a Link (portraying a common citizen) before he is banished to the Twilight Realm by the Light Spirits.

Spirit Tracks
Dark Link appears as the final challenge of the Take 'Em All On mini-game in Castle Town. In this appearance, he attacks using a blade as dark as himself, that subsequently leaves a fitting black trail, and he can also place bombs and shoot arrows. He can also perform a jump attack like Link, only his is higher and much slower. Dark Link also mimics Link's sword attacks when he himself is not attacking, so Link must block his attacks and then counterattack. Strangely enough, the music when fighting him is the same as when Link chased the Ghost Ship during the second phase of the final boss of Phantom Hourglass. He slowly fades from a pure black to a translucent gray as he takes damage, and once defeated, he falls over on his back and disappears, his eyes eerily left open during the whole animation. The room he is fought in is the only one which contains Recovery Hearts, even though the hostess of the Take 'Em All On game says that there is no way to recover health in the challenge rooms. Contrarily to Ocarina of Time, Dark Link becomes lighter as he takes damage, becoming nearly transparent when he is defeated.

The Legend of Zelda comic
In the Legend of Zelda comic published by Valiant Comics, Shadow Link is featured in the "Coming Home" story of the fifth issue. While Link is away in Hyrule, Shadow Link, disguised as Queen Seline and accompanied by Thunderbird, attacks the monarch of Calatia and defeats her using her own magical powers. He then locks her away in the tower of the Calatia Palace, taking over her kingdom and making her people suffer under his rule. When an unsuspecting Link returns to Calatia to visit his parents, he is violently greeted by his father, claiming that Link is not his son and ordering him to leave and never come back. Confused, Link begins to travel around Calatia but receives the same mistreatment with everyone else in town, and so he decides to see Queen Seline to figure out what has happened. When Link goes inside the palace's throne room, he finds that Shadow Link and Thunderbird have made the queen their prisoner and taken her place instead.

Once Queen Seline explains to Link what has happened, Shadow Link takes his both prisoners and sentences them to death for committing treason against their own king. The queen then halts him and demands her right of a life trial since it is Calatian Law that anyone sentenced to death has the right to trial  by combat to prove their innocence. Thunderbird questions Shadow Link if it is wise to let the restless citizens witness such an event, but still Shadow Link accepts Seline's challenge to thus crush the people's spirits by defeating their queen again. In accordance with the ancient laws, Seline chooses Link to fight in her place, and Link agrees.

Shadow Link tries to persuade Link to leave by disguising himself as Princess Zelda and appearing to him as a projection urging him to return to Hyrule, for it is under attack. However, when Link refuses, Shadow Link decides to ask Ganon for help in defeating Link. Ganon explains to that Shadow Link will be able to easily defeat his good counterpart since tomorrow is the Day of the Triforce, which is when, once each decade, the three Triforce pieces disappear for reasons unknown from dawn to dusk.

During the battle, after a short struggle, Shadow Link easily bests the young hero, and just as Shadow Link is about to deliver the final blow, a swift move by the real Link causes for the both of them to dangle  from the edge of the arena, getting ready to fall into the fire pit  below. Link angrily explains that he had to let Zelda face her doom alone just so that he could put an end to Shadow Link's tyranny, but just then the fake Link explains that Zelda lives and it was all a trick done by him. With Shadow Link's sword gone and Link's sword point at the back of Shadow Link, Link threatens to kill his counterpart unless he orders the  Daira guards to drop their weapons, which Shadow Link obediently commands.

Super Smash Bros. Melee
Dark Link, as he appears in The Adventure of Link and Ocarina of Time appears in the Event-match "Link's Adventure", where he must be defeated with Link on the Hyrule Temple stage. However, as this is a simple color-swap of Link, this can be applied to any character through the Debug menu only accessible through Action Replay or the name-entry glich.

Super Smash Bros. Brawl
Link is able to take on the appearance of Dark Link as an alternate costume in Super Smash Bros. Brawl. This version mostly resembles the one featured in the Twilight Princess cutscene.

Melee's version of Dark Link (which in turn is based of Dark Link from The Adventure of Link and Ocarina of Time, with a completely black appearance) reappears in the event match "Dark Link Duel" on the Bridge of Eldin stage. Unlike the alternate costume, the Dark Link in this event is completely black, as opposed to Link's alternate costume, which is mostly gray and black with red eyes. As in Melee, Link is the only option to fight against Dark Link. However, unlike Melee, this battle is fought as a Stamina match, making him more like a traditional Legend of Zelda enemy. A similar event, known as Battle of the Dark Sides, is featured for two players, in which Dark Link is fought by Link and Samus together, but is similarly accompanied by Dark Samus, an entity that, like Dark Link, is completely black, instead of resembling the canon Metroid character of the same name.

Ocarina of Time manga
In the Ocarina of Time manga, Link meets up with his shadowed doppleganger at Kakariko Village. From Beneath the Well, Dark Link emerges, ready to defeat the original Link. The original Link managed to defeat his dark self by learning that the shadow monster is  only as good as Link was then. So to defeat him, Link had to become better than he was before. Slicing Dark Link in half, the dark hero was not yet done. Dark Link then returned riding on a Dark Epona. Link countered and defeated Dark Link once again with the use of his own Epona. This Dark Link replaced Bongo Bongo as boss, most likely because the Shadow Temple didn't appear in the manga.

Four Sword Plus manga
In Four Swords Plus, Shadow Link is shown as a spawn of the mirror. He first appears when Link pulls the Four Sword from the pedestal, and re-appears numerous times to halt the four Links' progress. At the end, Shadow Link breaks the Dark Mirror, killing Vaati. It should also be noted that Dark Link wasn't evil, but he wanted to be recognized by the other  Links.

Man of Mystery
Dark Link's origins are wholly unknown, but there are many speculations. There is evidence to suggest that Dark Link is the ghost of a past warrior that is related to Link. Others believe in a sort of dead-man-switch technique, Dark Link was created by Ganon himself as insurance, should he fall to Link's blade (as he did in The Legend of Zelda, hence Dark Link's appearance in The Adventure of Link).

Still other theorists subscribe to theories that state that Dark Link was created out of Link's "heroism" or "goodness": because Link is the hero that he is, Dark Link arose to complete Link's dark side. Because of this, it is a widely-accepted theory that Dark Link is the force that balances Link, and possibly even the spark that keeps him alive. With that in mind, many also believe that Dark Link cannot truly be defeated because this might also result in Link's death. Yet another theory is that, since Link must be pure in order to touch the Master Sword, the gods extracted his dark side from his soul, leaving only his light; his dark side is Dark Link, whose ultimate wish is to reunite himself to his holy counterpart. And finally, popular theories link Dark Link to the Triforce; there are even some who go as far as to say that Dark Link embodies a "fourth piece" of the Triforce and exists to balance out the powers of the goddesses in Hyrule or as an "anti-manifestation" of such powers.

However, it seems more likely that Dark Link is simply a powerful spell cast by Ganondorf, Thunderbird in The Adventure of Link, and Malladus in Spirit Tracks.

Dark Mirror
The Dark Mirror in Four Swords Adventures is said to be the source of all the Shadow Links. It is said that one can look into the mirror and pull out their dark reflection. Ganon obviously did this, and stole the mirror, because all of the Links came from this source.

Tale of the Twili
In Twilight Princess, the Light Spirit Lanayru tells Link a story warning him about the corrupting power of the "Fused Shadows", as well as giving their origins. As part of the visual aid, Link and his childhood friend Ilia represent corruptible humans, while the corrupt sorcerers who would become the Twili are represented by three copies of Link with colorless clothing, black skin, and glowing, red eyes. These Dark Links are merely a representation of evil.

Trivia

 * It has been noted that Dark Link is akin to Link in The Legend of Zelda as Peter Pan's shadow was to Peter Pan in the production, Peter Pan. Both characters struggle with their shadows, both defeating them in order to move on with their quests, and both shadows have similar moves and actions used to try to outwit their true form. The fact that Peter Pan and Link both have similar attire only emphasizes such a connection. Despite these similarities, however, there has been no confirmation of a connection between the two by Nintendo, and any perceived connection is merely fan speculation.
 * In his appearance in Ocarina of Time, Dark Link appears next to a dead, blackened tree. This may serve as a contrast to the living green trees that surrounded Link in his youth, and to emphasize the light/dark scenario.
