L-canceling
L-canceling (an abbreviation of lag canceling or L button canceling, also called smooth landing on the official Super Smash Bros. website) is a technique in Super Smash Bros. and Super Smash Bros. Melee that allows characters to act faster than usual when landing in the middle of an aerial attack. L-cancelling is done by pressing a shield button 11 frames or fewer before landing during an aerial attack in Smash 64 (the grab button also works because of its unique properties), or by pressing the shield button 1 to 7 frames before landing in Melee.
Only regular aerial attacks can be L-cancelled; special moves that have landing lag cannot. If an attack is auto-cancelled then L-cancelling has no effect. All aerials can be cancelled except Mr. Game & Watch's nair, bair and uair.
In Super Smash Bros.
Better known as Z-cancelling as the Z button is the shield button, L-cancelling in Smash 64 is performed by pressing Z 11 or fewer frames before landing. Doing so causes the character's regular landing animation to play instead of the air attack's landing animation, reducing their lag to 4 frames. Compared to lag intervals in the 20-30 range, this can allow incredible attack speed when combined with techniques such as double jump cancelling, resulting in shield break combos.
In Super Smash Bros. Melee
L-cancelling in Melee is performed by pressing L, R or Z up to 7 frames before landing. Doing so causes the aerial attack's landing animation to play at double speed, cutting the lag time in half (rounded down). While not as potent as the previous game, the decrease in lag is still significant enough to make L-cancelled aerial attacks better than comparable ground attacks. This is especially true for characters with heavier aerial landing lag, most notably Bowser and Ganondorf. Unlike in Smash 64, L-Cancelling in Melee can be performed only when L, R or Z are pressed once during the activation period, otherwise the effect will be canceled.
In later games
L-canceling is not present in Brawl. It was removed because, like wavedashing, Masahiro Sakurai felt it made the gap between beginner players and advanced players too large. The lack of L-canceling acts as an indirect nerf to characters that have aerial attacks with heavier landing lag and/or low jumps (most notably Ganondorf).
L-canceling continues to be absent from Super Smash Bros. 4. However, equipment may have the Smooth Lander effect, which automatically provides a similar result. Depending on the number of times the effect is stacked, landing lag from aerials can be cut to 0.7x, 0.6x, or even in half as in Melee.
Notes
- It is impossible to L-cancel Mr. Game & Watch's neutral, back, and up aerials due to using a nonstandard landing lag state (as they function as special moves, which also cannot be L-cancelled), similarly to how Ness's up and down smashes act unusually.
