Vanish

Vanish is 's up special move in Super Smash Flash 2.

Overview
When performed, Sheik throws a Deku Nut at the ground and vanishes into thin air with an explosion surrounding her. Opponents hit by the explosion are dealt 10% flame damage and moderate upward knockback. She then reappears in a cloud of smoke a short distance away straight upward, or in a direction influenced by the directional inputs. Upon reappearing, the attack has a strong wind hitbox that can push opponents far away and even KO them if the player is caught by surprise.

During the start-up, Sheik is granted intangibility frames and in the air can steer left or right slightly, and she is able to grab the ledge. Landing with Vanish directly on a platform produces heavy lag, and reappearing in the air leaves her helpless. Oddly, the wind at the end of the move is considered a projectile and as such it can be reflected back at Sheik, potentially gimping her and pushing her offstage should this happen.

Origin
Vanish is based on how Sheik often vanished in , much to Link's bafflement. However, sometimes fire or sand concealed her disappearance while she quickly threw the Deku Nut on the ground, much like a smokey explosion does in SSF2. Impa, the only other Sheikah in the game, could perform this ability; it is one of the "Sheikah arts". Based on the effect of Deku Nuts in-game, it is implied that Link was paralyzed by the Deku Nut and regained his senses following Sheik's departure, unlike Vanish necessarily involving Sheik teleporting.
