Up attack

An up attack in Super Smash Flash, called air attack upward within the How to Play section (despite not being completely aerial-restricted), is an attack that is performed by pressing the attack button with putting the up key. Despite the name, the up attack is not truly an equivalent to the up special move found in the official Super Smash Bros. games, as attacks within this range include high attacks, like high kicks and upward punches, that can attack opponents in the air. Also, whereas up specials can be used for recovering, up attacks fail to be actual recovery moves, as they do not provide an additional jump or similar means to get back on the stage.
Due to the game's physics, every character's up attack shares damage values with the fighter's , and, due to that, will always knock opponents at a vertical angle.
Characters whose attack cooldown stat is lower than their attack length stat will perform their down aerial animation (albeit still with the up attack's attackbox properties) after an air attack upward 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.

The following is a list of all the up attacks in SSF per character, with a brief description, the amount of damage per frame dealt, and a explanation related to whether or not the attack contains a projectile. Every character uses their attack boost stat as their default speed during this move.
