Mario using his forward smash in Melee
Mario using his forward smash in Brawl.

A forward smash, abbreviated f-smash and officially known as a side smash attack (横スマッシュ攻撃), is a smash attack that any character can perform by tapping the control stick in a horizontal direction and pressing the attack button immediately afterward or simultaneously, or by tilting the C-Stick in a horizontal direction (except in Melee's single-player modes). Starting in Melee, forward smashes can be charged for a maximum of one second (or 60 frames), resulting in up to 1.4× the damage and knockback. In Ultimate, they can be held for an additional two seconds (120 frames) upon reaching full charge.

After tapping the control stick forwards, there is a 3-frame window wherein a forward smash can be performed. If the attack button is pressed too late, a dash attack will be performed instead. Pressing the attack button on the last possible frame results in a small step forward smash. In all games except Super Smash Bros. Brawl, forward smashes can be pivoted.

Like forward tilts, certain forward smashes can be angled in up to 3 directions; a select few forward smashes in Smash 64, however, can be angled in up to 5 directions. In Smash 64 and Melee, the control stick or c-stick must be tapped in the desired angle at the start of the move to angle it. From Brawl onwards, however, the attack can be angled by holding the control stick or C-stick in the desired angle as the move's charging period ends.

Notable forward smashes

  • From Super Smash Bros. Melee onwards, Link, Young Link, and Toon Link (except the latter in Ultimate) possess the only forward smashes that are natural combos.
    • Furthermore, the first hit of Link's forward smash in Ultimate is capable of launching a unique sword beam projectile when Link is at 0%. This projectile travels quickly over a long distance, and its size and damage output are greatly increased by charging the attack. It also substantially increases the damage output of the attack when used at close range.
  • Mega Man, Olimar, and Villager's forward smashes, as well as Link's aforementioned Ultimate sword beam, are the only four forward smashes which are projectiles. Of those two, Mega Man and Link's projectiles are the only projectiles to increase in hitbox size as the attack is charged. Villager's is one of the only projectiles that falls downwards instead of traveling forwards. Mii Gunner's forward smash may appear to be a projectile, but is technically not, as its shots do not act independently of the Mii Gunner.
  • Ness's forward smash is able to reflect projectiles. This property is shared with Lucas's very similar forward smash, as well. They are the only two non-special attacks with this property.
  • For her forward smash, Peach is capable of using three different weapons, each of which have different properties. In Melee and Brawl, it is entirely random which of the three is used for the attack. In Smash 4, the attack cycles from tennis racket to golf club to frying pan, making its use more consistent. In Ultimate, it was changed again to be angle-dependent (neutral for golf club, up for frying pan, down for tennis racket). Daisy, as her Echo Fighter, inherits those properties for her forward smash.
  • In Brawl, Wario's forward smash has both transcendent priority and super armor, a combination which makes it nearly impossible to intercept when combined with its high speed.
  • In addition to possessing three different variants based on angle, Little Mac's forward smash is the only other forward smash to possess super armor. The latter property is shared with all of his smash attacks.
  • Palutena's forward smash has a reasonably powerful windbox just beyond the reach of the main portion of the attack, allowing it potential usage for niche edge-guards and gimps.
  • While charging a forward smash, Corrin holds Omega Yato forwards to grind enemies at close range with its teeth for several potential weak hits. This makes it the only forward smash to have a hitbox while charging.
  • The pattern of the gunshots in Duck Hunt's forward smash, as well as the angles at which they launch, are slightly randomized. They will also become spaced further apart, and thereby reach further, if the attack is charged.
