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 to 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 pictured on the game's box art.

The Legend of Zelda animated series
Link wields a sword very similar to the Magical Sword in the animated 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."

Captain N: The Game Master
Although not explicitly referred to as the Magical Sword, Link in Captain N: The Game Master wields a sword similar to the Magical Sword. Like in the Zelda animated series, Link can use it to zap enemies, and this time, he can be seen attacking enemies with the sword rather than just using it to defend himself or parry.

Soulcalibur II
The Magical Sword is one of Link's weapons available in Soulcalibur II, although it is known as the Magic Sword instead. Paired off with the Magical Shield, the Magic Sword and the shield can be bought in the Aldebaran Shop, Algol Shop, Pollux Shop, or the Merak Shop for 3000 Gold while playing the Weapon Master Mode. Although Link's offense and defense will not increase when he equips these weapons, the Magic Sword will cause 40% block damage, compared to the usual 10%.

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 canonical 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. Furthermore, the Master Sword is said to rest in its pedestal in the Lost Woods forevermore at the end of, which chronologically comes before The Legend of Zelda and The Adventure of Link.
