Side Special Moves are special techniques able to be done by Fox, Falco (in Melee), and Wolf in Super Smash Bros. Brawl. It involves the user focusing energy in one direction then dashing forward at a blinding speed. It was introduced in Super Smash Bros. Melee as Fox and Falco's side special move. It returned in Brawl, being used a bit differently. In Super Smash Bros. for Wii U and Nintendo 3DS, the move returns and no longer puts the characters into their helpless state. In this game, they also have alternative moves to use as well as the default ones.
Fox was the first to master this technique. He will kneel down facing forward, then dash forward. The "illusions" behind him will cause damage to those who try to sneak up on him. Fox Illusion can be used as a recovery move and is moderately ranged.
Fox Burst is the first of Fox's Side Special Moves that can be used through customizations in Super Smash Bros. for Nintendo 3DS and Wii U. Fox does a dash that deals no damage, but an explosion occurs where Fox stops.
Wolf Flash is Fox's second Side Special Move that can be used via customizations. It is the same as Wolf's Side Special Move in Super Smash Bros. Brawl. Fox quickly dashes at the opponent, leaving a trail of purple mist behind him.
Falco mastered this in Melee, though his was simply a shorter ranged yet faster version of Fox's. In Brawl, it has the same amount of range. Falco Phantasm deals slightly more damage than Fox Illusion and can send opponents downward if he lands the attack on them while in the air.
Falco Phase is the first of Falco's Side Special Moves that can be used through customization. Falco can't be hit while dashing, but the move doesn't hit opponents, either.
Falco Charge is second of Falco's Side Special Moves that can be used via customization. Falco travels a shorter dash that hits much harder at the beginning of the move.
Wolf mastered this move in Brawl. Very much unlike Fox's or Falco's, but Wolf will dash diagonally upwards, instead of straight forward. If the trail hits an opponent, he/she will take very little damage, but if Wolf makes contact with the opponent at the very end of the move, he will send the foe downward with great power. The Wolf Flash also makes for a more successful recovery than Fox's or Falco's.
