Down attack

A down attack in Super Smash Flash, called special attack within the How to Play section (not to be confused with an actual special attack), is an attack that is performed by pressing the attack button with putting the down key. The down attack is more or less an equivalent to the down special move found in the official  games as attacks within this range include close-ranged attacks that surround the character's frame, like 's Materia orbs, or launching attacks that directly make the character travel a far fixed distance, the most out of all the other attacks, like 's.

Unlike the other attacks in the game, down attacks cannot be held indefinitely with the attack button and attempting to do so will make the character to perform their instead afterwards. However, finding and carrying an item makes it possible to hold these attacks indefinitely, as this is the only attack that is allowed to be used while holding an item.

Roll attack
Some down attacks propel characters forward without using the character's attack boost stat as movement speed. Coined by Dark Ermac, those down attacks are referred to as roll attacks, and have unique attributes: Characters with roll attacks are able to cancel any attack into a roll attack instantly. Roll attacks ignore characters' attack boost, attack length and attack cooldown statistics. Lastly, roll attacks cannot be cancelled by simply turning around, albeit they can still be jump cancelled.

Characters without roll attacks can instead execute a technique called down augmenting, which allows the fighters' attacks on the ground to deal the same damage as said characters' down attacks. It is performed by simply pressing or holding down quickly after inputting an attack.

List of down attacks
The following is a list of all the down attacks in SSF per character, with a brief description about the move. Whether or not each down attack is a roll attack or contains a projectile will be listed as well. Characters who lack roll attacks will instead simply reuse their attack boost stat as their speed.
