Light Arrow

The Light Arrows are Zelda's and Sheik's Final Smash that was shown in CoroCoro magazine beforehand and confirmed at Smash Bros. DOJO!!. When used, Zelda/Sheik draws a large bow and sets an arrow. During this time, any characters in her line of sight will flinch. A second later, the Light Arrow is released, dealing significant damage and likely KO'ing the struck characters. The move goes through walls, and when used, the match will pause as the camera does a slow-motion close-up of each hit character in order (similar to the Dragoon).

While the basic move is the same whether Zelda or Sheik uses it, there are some differences. The primary difference is that Sheik sends opponents flying almost parallel to the Light Arrow, while Zelda sends them at more of a 45 degree angle. Sheik's Light Arrow also does more damage, but not significantly.

Damage & Properties
The damage & properties of the arrow are slightly different for either character. The move can hit a maximum of 6 targets (three lots of Ice Climbers) but the damage and knockback weaken for each target hit. Thus if used on many opponents, it may not KO the ones in the back, even at higher percentages.

Spacing is very important when using the Light Arrow. If the opponents are too close together, they may collide with each other and prevent KOs from happening. This is even more important in the Sheik version where opponents are launched at a very low angle.

Zelda's Light Arrow

 * First Target about 42%
 * Second Target about 32%
 * Last Target about 24%

Sheik's Light Arrow
However, these numbers can be further weakened with more targets. (i.e the Ice Climbers)
 * First Target about 48%
 * Second Target about 36%
 * Last Target about 28%

Origin
In conjunction with the Master Sword, Light Arrows have been used throughout the Legend of Zelda series as the ultimate weapon against Ganondorf. The concept for them probably comes from from the original NES Legend of Zelda, in which Link used a similar weapon called the Silver Arrow to defeat Ganon. Link was first able to wield the Light Arrows in The Legend of Zelda: Ocarina of Time on the N64, where he utilized them in the penultimate showdown with Ganondorf.

Light Arrows appeared again in The Legend of Zelda: The Wind Waker for the Gamecube for Link to use. However, for the final boss battle, Zelda is the one who attacks with the Light Arrows, firing them to stun Ganondorf whilst Link strikes with his sword. In The Legend of Zelda: Twilight Princess, only Zelda can equip the Light Arrows, which she summons from the Light Spirits to help Link triumph over Ganondorf on horseback. In all of these instances, Light Arrows were the only method of causing damage to Ganondorf, but when used on any other enemy, they were instantly destroyed in one shot.

Zelda
''Princess Zelda's Final Smash. She wields a mighty bow of light with which she can attack from afar. Her arrow travels in a straight line and flies through all characters unlucky enough to be in the way. This attack cannot be blocked. The more enemies there are, the higher the chances to get them all with one shot. More is always better!''

Sheik
''Sheik's Final Smash. After grabbing a Smash Ball, Sheik will be able to wield a bow of light. The arrow fired from this bow has the power to pass through multiple targets, so it will damage all enemies in the direction it flies. This, coupled with its shield-breaking power, makes it even more terrible. Even in Sheik form, Zelda's ability as an archer is undiminished.''
