Charge-cancel
Charge-canceling is the act of halting the charging of an auto-chargeable special move, such as Samus' Charge Shot. This allows the user to store a partial charge and resume charging the move later.
While charging such an attack on the ground, players can cancel the charge and (usually) store it by pressing a shield or grab button, or tapping sideways on the control stick or D-pad to roll out of the charge. If they are in the air while in their charging state, canceling it with a shield or grab button will make them cancel it with an air dodge instead. In Ultimate, these moves can also be canceled by jumping.
If a character is hit while charging one of these moves (other than Bonus Fruit and Limit Charge), they will lose the charge completely and have to start over, regardless of whether they had stored a charge before.
Due to its buffer system, charge-canceling Giant Punch in Brawl will result in Donkey Kong performing an air dodge if the input is entered late into the charge animation.
In Smash 4 there is also a variant known as Instant Charge-Canceling which consists of inputting a neutral attack, tilt attack or Smash attack in a certain timing without having to cancel the chargeable move with the shield. It is exclusive to Cloud, Diddy Kong, R.O.B., and Sheik.
In Ultimate, there is also a variant known as Charge Jump Canceling which is performed by attempting to cancel a chargeable move performed in the air by initiating a double jump shortly before landing on the ground.
List of moves that can be charge-canceled
Prior to Ultimate, Samus and Mii Gunner were the only characters who could not charge cancel in midair, since Charge Shot and Charge Blast were unable to be charged in midair; this was changed in Ultimate. Additionally, Mewtwo's and Lucario's auto-charge specials (as well as Sheik's in Melee). will continue charging even at max charge unless canceled or fired during that period, as opposed to automatically stopping like everyone else.
Also prior to Melee, characters could use a normal attack button to unleash the charged attack mid-charge as well.
