After a short delay, Pikachu moves in a straight line in the direction in which the player's control stick is tilted, or upwards if it is not tilted. A tilt of the control stick in a different direction will cause another, similar burst. The high speed of this move renders Pikachu nearly invulnerable, but it is exposed at the beginning, middle, and end moments, when it briefly holds still. Quick Attack requires much practice before players can effectively take advantage of its two-direction functionality.
 In Super Smash Bros.
This attack deals no damage (making it the only special move in the game that cannot affect the enemy). However, it is one of the best recoveries overall. Pikachu is notable for having one of the most diverse recoveries as well. Pikachu has multiple invincibility frames during the beginning and middle. It is possible to attack Pikachu only before and after the bursts. Given this, Pikachu can ledge-stall indefinitely. The range of this move also allows Pikachu to go far out from the edge to edgeguard. It is also possible to travel with almost no change in direction between bursts. Pikachu can alternate between taunts and Quick Attack, each canceling the other. Finally, it can be used to escape situations and can go through a portion of the wall in Break the Targets.
Super Smash Bros Melee's Quick Attack is for the most part similar to the attack in Super Smash Bros. Unlike the original, Melee's deals 1-3% damage per hit to characters Pikachu passes through and has fewer invincibility frames. The attack has a huge range, but the second jump requires a minimum rotation of 38 degrees. New developments suggest that it may be possible to jump twice in the same direction, however. Pikachu can also cancel the move, like in Smash 64.
Pikachu can deal light damage to characters it passes through, being stronger in damage (5%, if hit twice by Pikachu pulling a 180°), but it has less range than in Melee. Thus, people often use Skull Bash as an additional recovery move. It has more invincibility frames by the edge, however. Pikachu's Quick Attack can also be cancelled into the ground, called QAC'ing. This is a very useful technique in competitive play and it is seen as a main way for Pikachu to approach many characters.
 In Super Smash Bros. 4
It has been confirmed in the E3 trailer that Quick Attack would be Pikachu's up special move in the upcoming Super Smash Bros. 4.
Quick Attack is a physical Normal-type attack introduced in Generation I in the Pokémon games. It has 40 power, 100% accuracy, 40 PP, and +1 priority. This means that the attack will hit before attacks of lower priority regardless of speed (or inverse if priority is higher), but should enemy use a move of +1 priority, the order will be determined normally. Quick Attack can never be learned by technical machine usage but Pikachu can learn it by naturally leveling up.

Move at ultra-high speed. Tilt the Control Stick very quickly in any direction before Pikachu moves to change its direction.
