Super Cancel

Super Canceling is a mechanic introduced in the Street Fighter III series.

Description
Super Cancelling is performed while attacking (usually during a special attack), by quickly inputting the character's Super Art/Super Combo during the attack animation.

Super Cancelling makes it easier to string together higher-damage combos than simply performing the Super Art/Super Combo on its own. The damage done by the Super Art/Super Combo itself is lowered; this is due to the programming of Super Cancels in the Street Fighter III series, and damage scaling in the Street Fighter IV games.
