Side attack

A side attack in Super Smash Flash, also called forward attack and referred to as "smash" attack (not to be confused with an actual smash attack) within the How to Play section, is an attack that is performed by pressing the attack button with putting the side key.

Despite the name, the side attack is not truly an equivalent to the side special move found in the official  games but essentially functioning similar to a dash attack or even a continued combo attack from a neutral attack, as attacks within this range include successive attacks, like kicks and punches, that normally deal more damage, there are also includes projectile-based attacks, like 's machine gun or moves that slightly make the player move a few inches after the attack was performed, like 's forward lunge kick.

Characters whose attack cooldown stat is lower than their attack length stat will perform their up attack animation (albeit still with the forward attack's attackbox properties) after a side attack if the attack button and the directional input stay held. Other characters will instead enter a small cooldown time (time varies from character to character) where they cannot attack at all, but can still move.

List of side attacks
The following is a list of all the side attacks in SSF per character, with a brief description, the amount of damage per frame dealt, and an explanation related to whether or not the attack contains a projectile. Whether or not a side attack, on its first frame, gives a character a horizontal speed boost will be noted as well. In cases where a character does receive a momentum gain, the boost value will be written as well. Otherwise, characters will simply reuse their attack boost stat, which can be viewed in each SSF character's individual hard data page.
