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 Zelda or Sheik uses their final smash they draw out a large bow and nocks it with a light arrow. The arrow is fired across the stage and everyone within a horizontal line of Zelda is hit instantaneously. If an enemy is hit, the move deals about 44% damage for Zelda, and 50% for Sheik. Depending on who uses it, the knockback trajectory will be different. If Sheik uses it then the character hit goes parallel to the arrow's trajectory,and if Zelda uses it then the character hit goes at a slightly higher trajectory. It is widely believed that it is one of the few moves to be a one-hit KO, but sometimes there is a chance to jump back on stage if attacked.

Light Arrows are a recurring Weapon in the Zelda series, first appearing in Ocarina of Time and typically playing an important role in the fight against Ganondorf. In Wind Waker, they are obtained in the final dungeon by defeating Phantom Ganon, and are used by Zelda to aid Link in fighting Ganondorf. In Twilight Princess, they are not actually used by Link, instead, during the final battle, Zelda prays to the light spirits and they grant her a Light Bow and Arrow, which she then uses to aid Link in his fight.

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.''
