Pikachu (SSB)/Up special
Overview
This move is known as Quick Attack, where Pikachu travels in a direction, and can optionally travel in a second direction with warp speed. The direction of second warp must be at least 45 degrees different than the direction of the first warp. It deals no damage at all but is the best recovery move in the game as it covers a huge distance very quickly, making it hard to edgeguard Pikachu if it uses Quick Attack properly.
Quick Attack is also known to have invincibility frames during the beginning and middle of the move. Pikachu players can then use an technique called ledge-stall, where it uses Quick Attack on the ledge for as long as it likes and Pikachu will be invincible of a infinite amount of time as seen in this video. With Quick Attack's said long range, invincibility frames, and quick speed, Pikachu is also capable of escaping out of situations and combos. However, if a Pikachu player does not land the Quick Attack in a safe place, he or she are likely going to get punished due to Quick Attack's ending lag.
