Magical Sword

The Magical Sword is the final and strongest of all three swords in The Legend of Zelda. This is also the sword wielded in The Adventure of Link.

The Legend of Zelda
Link finds the Magical Sword in the possession of a man who lives underneath a grave in the cemetery. The old man requires that Link either have at least twelve Heart Containers in his life meter before he gives Link the sword. The sword has the same properties as all of the other swords in the game, such as the ability to shoot Sword Beams, but is simply stronger. In fact, the weapon is entirely optional, as only the Silver Arrows and any kind of Sword are required to defeat Ganon.

The Adventure of Link
Link departs on his quest with the magical sword in his left hand and the magical shield in his right. Link is able to augment the sword's ability to fire Sword Beams with the Fire spell, which allows the sword to shoot fireballs even if Link is not at full health. The sword will also do more damage if Link levels up his Attack stats. The sword is also pictured on the game's box art.

Soulcalibur II
In the fighting game Soulcalibur II Link made a special guest appearance as a fighter. One of his weapons was the Magical Sword, and although it looks different from the original images of the magical sword (having a purple hilt like the Master Sword and the Triforce on its guard), it still bears its name. The Magic Sword is capable of piercing defenses, but the Magic Shield it is paired with apparently hasn't held up as well, and is slightly weak to impact.

Cartoon Series
Link wields a sword very similar to the Magical Sword in the cartoon series. It is much smaller than any depiction of the sword featured in official art, however, and resembles a long dagger more than a sword. Link is almost never shown to slash with it, using it only to parry and attacking using its Sword Beams. In the episode "Stinging a Stinger", the sword is given the name "Crissword."

Theories

 * There is a some debate as to whether or not the Magic Sword is in truth the Master Sword. Zelda.com's encyclopedia section refers to them both as the same weapon, but this website's canon status is dubious. Some fans speculate that since the Master Sword's absence in a game featuring Ganon is curious, the two swords could be the same. This is doubtful, however, as the Magical Sword is never referred to as the Blade of Evil's Bane, only as a very powerful sword that is not even essential to defeat Ganon.
 * It has been thought that the Hero's Spirit's sword is the Magical Sword. However upon closer observation, it doesn't look exactly like the Magical Sword.
