Forward smash

Marth using his forward smash in Brawl

Corrin using his forward smash in Smash 4.

A forward smash (officially known as a side smash attack (横スマッシュ攻撃, abbreviated f-smash, internally AttackS4), is a smash attack performed 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). After tapping the control stick forwards, there is a 3-frame window (5-frame in Ultimate) where 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.

Starting in Melee, forward smashes can be charged for a maximum of one second (or 60 frames), multiplying their damage by up to 1.4×. In Ultimate, with some exceptions, full charges can be held for two seconds (120 frames), for a total of 3 seconds (180 frames).

Forward smashes are typically powerful strikes with a hitbox directly in front of the character, being the strongest type of smash attack on average, but also tending to have the highest startup and/or ending lag. As a result, most forward smashes are situational and reserved for hard reads or hard punishes, often being a character's strongest shield break punish when fully charged. Some forward smashes shift the user forward a significant distance, and some have various armors under certain conditions.
