Master Sword

"But then, when all hope had died, and the hour of doom seemed at hand... a young boy clothed in green appeared as if from nowhere. Wielding the Blade of Evil's Bane, he sealed the dark one away and gave the land light."

- The Legend of Zelda: The Wind Waker

The Master Sword (also known as The Blade of Evil's Bane ) is typically the most powerful weapon in a Zelda game for general usage; with the exception of the Biggoron Sword, Gilded Sword, Great Fairy's Sword, and the upgrades in A Link to the Past. The Master Sword will usually have a power level of two or three unlike the starting sword. The sword's exact origins are unknown, but it is presumed that the makers were the Seven Sages that helped seal Ganon during the Imprisoning War.

The Legend of Zelda and The Adventure of Link
The Master Sword was believed not to appear in these games; however, according to Nintendo's official Zelda site, the Master Sword is listed as having appeared in The Legend of Zelda and The Adventure of Link (see Magical Sword).

A Link to the Past
This was the game when The Master Sword properly was called that. It is presumed, however, (as previously stated) that the Magical Sword of the first two Zelda titles is in fact the Master Sword, with this being the first time its proper name is used. The Master Sword here is the legendary blade that rests in the Lost Woods of northwestern Hyrule in a pedestal with ancient Hylian inscribed on it. The ancient text says the hero with three symbols of virtue will wield it on cataclysm's eve, reading: "The Hero's triumph on Cataclysm's Eve wins three Symbols of Virtue. The Master Sword he shall then receive, keeping the knights line true." However, this is likely relating the story of the sword's first master, the Hero of Time (who was the legendary Hero at the time of the Great Cataclysm), that triumphed over many enemies on the very eve of the Great Cataclysm and won the three Spiritual Stones, the necessary keys to open the way to the Master Sword. This would mean that the "three symbols of virtue" were the three Spiritual Stones, giving credence to the possibility that the stones may have been transformed into the Pendants of Virtue at some point following the Imprisoning War and retained their role as necessary keys needed to unlock the Master Sword from its resting place. If the inscription on the Pedestal of Time (the sword's pedestal) is referring to the story of the Hero of Time, this would suggest that the Hero of Time was a descendant of the Knights of Hyrule ("keeping the Knights' line true) and lend credence to the possibility that the Link in A Link to the Past is a descendant of the Hero of Time since it is noted that the Link in A Link to the Past is the last of the Knights' bloodline and that the Hero of Time kept the Knights' line true at the time of the Great Cataclysm (when all the Knights of Hyrule were wiped out). This sword has the power to emit a beam from its blade to attack enemies from a distance. This happens only when Link's health is completely full. It is the second sword acquired in the game, and the third and fourth swords are more powerful versions of the Master Sword.  The Master Sword is also called "the Blade of Evil's Bane", and has the power to repel evil magic.

Ocarina of Time
This legendary blade resides in the Temple of Time. To gain the Sword, Link must collect the three Spiritual Stones, and play the Song of Time on the Ocarina of Time to open the chamber where it is sealed. The Master Sword is the final key to the sacred realm and the temple of light, which houses the Triforce, and only the one worthy of the title of the Hero of Time can draw the Master Sword. In both Ocarina and the Wind Waker, the Master Sword locks away evil from Hyrule. When removed from it's resting place, its prime purpose becomes to help attack and reseal evil and restore peace to the world. When Link pulls the Master Sword out of it's pedestal, he travels seven years into the future. He can also return to the past by plunging the sword back. In the end of the game, the Master Sword is used by Link to defeat Ganondorf and seal him into the Evil Realm.

Oracle of Ages/Seasons
The Master Sword makes a reappearance in the Oracle series, fittingly as the most powerful sword in the game. When combined with the power of the Red Ring, the Master Sword is capable of taking down almost any boss in two to three Spin Attacks. The only way to unlock the Master Sword is to have finished one of the games, and to have started a linked game on the opposite game. When a certain secret in the game is found and told to Farore, she will upgrade the Noble Sword Link currently holds into the Master Sword. However, if Link still has the Wooden Sword, the Wooden Sword will become the Noble Sword, and the Master Sword will be found where the Noble Sword usually is.

The Master Sword, also fittingly, is the only sword capable of hurting Ganon without resorting to spin attacks.

The Wind Waker
The Master Sword is predominately referred to as the Blade of Evil's Bane in the Wind Waker legends and rests in a hidden chamber in Hyrule Castle, deep beneath the waves of the Great Sea. The Master Sword's use as a key to lock evil away is broken when a young Link unknowingly draws the blade under the direction of the King of Red Lions. He unwittingly awakens Ganondorf´s army from their ancient slumber. Later, Link learns that due to Ganondorf stealing the souls of the Sages, Fado and Laruto, the Master Sword had lost its power to repel evil and Link must awaken two new Sages in order to regain that lost power. Those Sages are apparently there in order to pray for the Master Sword and the Hero who wields it, and to keep it glowing with the power to repel evil.

Twilight Princess
The Master Sword within Twilight Princess is located deep within the Faron Woods in the Sacred Grove (the ruins of the Temple of Time). The blade is said to have once be held by the Legendary Hero. It is the one relic that allowed Link to break the curse that Zant places on him after the end of Lakebed Temple and return to his human form. Link then draws the blade from its pedestal, and Midna proclaims that the sword chose Link to become its new master.

The Master Sword in this game also allowed Link access to other numerous hidden temples later in the game (such as the Temple of Time). The sword's initial locations marks a link between A Link to the Past and Ocarina of Time, as it resides in the Temple's ruins, a place that is notably similar to the sword's resting place in A Link To The Past.

The sword is (in comparison with the shield and the overall height of Link) considerably bigger than in the other 3D releases. Regardless, the general design is consistent throughout them all.

Also there is a glitch that allows the player to get the Master Sword early on in the game. This glitch also gives Link the ability to transform into a wolf whenever he wants to early. View the glitch here: []

Light-Infused Master Sword
In the Palace of Twilight, Link fuses the Master Sword with the power of the Sols. This Light-Infused Master Sword enables Link to defeat most Twilight Monsters in a single blow. The sword is also capable of clearing away the dark fog which causes Link to revert back to wolf form. This upgrade is only usable while in the Twilight Realm.

Midna notes that the Sols' light being transfered to the Master Sword is the work of the gods of the Twilight Realm, and that they, too, are on Link's side.

During the boss battle against Puppet Zelda, the light infusion of the sword gives it the ability to repel projectile attacks being sent at Link in order to damage the foe.

At the end of the game, Link (before leaving Ordon Village), places the sword back in it's pedestal in the Sacred Grove.

Cross-References
In popular culture, the Master Sword suggests direct comparisons to the sword Excalibur, a mythical blade weilded by King Arthur throughout his journeys in medieval times. Link is the only one that has the power to relieve the sword from its stone pedastal, and is the only one that the sword itself will allow to use, similar to King Arthur's use of Excalibur throughout his mythical reign. Both sword harness mythical, magical powers only of use in times of strife and recession as both Hyrule and Camelot were during their respective times.

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.
