A yellow ribbon of magic spins around Zelda, damaging nearby opponents and causing her to disappear. She then reappears in the direction held on the control stick (or directly above her original location if the control stick is not moved). After reappearing, Zelda becomes helpless.
In Super Smash Bros. Brawl, Zelda teleports a slightly shorter distance than she did in Melee, but also creates a small explosion (similar to the one made by the initial part of Sheik's Vanish) upon reappearing, dealing some damage and knockback. Farore's Wind is hard to sweet-spot the ledge with.
In Super Smash Bros. 4, the explosion when Zelda reappears is much more powerful. The first hit also sends the target vertically into the second hit, a technique nicknamed "the Elevator", which is able to KO at medium percentages depending on the character (about 70% on average) if sweetspotted. The move has changed a little aesthetically, with the ribbon appearing less realistic. It is now much easier to sweetspot the ledge with.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
In Super Smash Bros. Ultimate, Farore's Wind has less startup and ending lag. When Zelda performs this move, she travels faster, making it more difficult to angle and travels a shorter distance. After reappearing, Zelda can drift sooner in air. Farore's Wind has less base knockback, difficult to KO opponents while the move on air deals higher knockback.
The original Farore's Wind is a spell from The Legend of Zelda: Ocarina of Time. Link can use it to mark a place in a Dungeon and then return to that warp point at a later time. It is the spell which is representative of Farore, the Goddess of Courage.
