Momentum canceling

Momentum canceling is a technique employed in Super Smash Bros. Brawl that is important in competitive play. The technique involves executing certain actions to halt or reduce the aerial momentum of a character who is knocked into the air. Since, in Brawl, attacks and air dodges can be performed while tumbling and reeling, it is possible to use these moves, in combination with others, to avoid crossing blast lines and being KOd. A prominent example of a momentum canceling move is Mr. Game & Watch's Oil Panic, which negates all aerial momentum, and may be used after tumbling has ended.

When combined with directional influence, momentum canceling can allow characters to survive to percentages as high as 200%. While less effective against attacks with high knockback scaling, such as Luigi's forward smash, this technique is essential in competitive play and helpful in casual matches.

How to perform

Momentum canceling involves two steps:

1. Once knocked into the air, a character must use an aerial attack as soon as possible, to end or tumbling or reeling. If knocked back horizontally, the character's fastest aerial is usually preferable, and in the case of Ike or Snake, an air dodge may be a better option.
2. If knocked vertically, the character must initiate a fast fall, which can be achieved by using the c-stick (or the Wii remote's d-pad), to perform a down air in conjunction with the previous step. If knocked back horizontally, a special move that negates unwanted momentum should be used. If the character has none, a midair jump should instead be performed.

Vertical momentum canceling

To momentum cancel when launched vertically, a character must perform an aerial attack and fast fall. Both the aerial and the fast fall can be achieved by tapping down on the c-stick, since this will input a dair and fast fall simultaneously. It should be noted that stall-then-fall attacks do not assist vertical momentum canceling. Players whose characters possess stall-then-fall dairs should instead tap the c-stick in a different direction to carry out a different aerial, and tap the control stick down to fast fall.

Each character's potential to vertical momentum cancel hinges on the difference between the speed of their regular fall, and the speed of their fast fall. Link, who possesses the largest difference, gains the most benefit from vertical momentum canceling, while Wolf, who has the smallest difference, benefits the least. It is important to note that, despite the existence of particular special moves that negate vertical momentum, all characters can survive longer by using this basic method, including Mr. Game & Watch.

Horizontal momentum canceling

Horizontal momentum canceling is notably more complicated than its vertical counterpart. The most basic method is to perform a character's fastest aerial, followed by a midair jump. If this technique is performed, every character is able to survive to percentages that are at least 1% higher than in cases in which it is not. The amount that each character benefits from this basic method hinges on two factors: the speed of their fastest aerial, and the properties of their midair jump.

Horizontal air speed is not a helpful factor, since Wario has fast horizontal air speed, but is poor at momentum canceling horizontally. It should also be noted that Ike and Snake yield better results from using an air dodge instead of their fastest aerial. Coincidentally, these two gain the most benefit from the basic method. Unlike vertical momentum canceling, there are multiple special moves that aid horizontal momentum canceling; some influence the character's movement, and others cancel it completely.

Character abilities chart

The following chart shows and ranks each character's horizontal momentum canceling abilities. Each test was carried out by hitting the character from the centre of Final Destination with the tip of Wolf's f-smash. This information is courtesy of OmegaTyrant.

• Rank shows the character's position in terms of the total of their percentages; the higher their rank, the better their ability to momentum cancel horizontally.
• Character / Attack / Special Move shows each character's name, their fastest aerial, and, if they have one, their special move that negates momentum.
• No MC, no DI shows the percentages at which each character is KOd without DI or momentum canceling. The first result is from testing with no controller input, and the second result is from testing with the control stick tilted toward the stage.
• Basic MC, no DI shows KO percentage when using the basic method of momentum canceling, but no DI.
• Special MC, no DI shows KO percentage when using their special move for momentum canceling, if any, but no DI.
• DI, no MC shows KO percentage when using DI, but no momentum canceling.
• DI, basic MC shows KO percentage when using DI and the basic method of momentum canceling.
• DI, special MC shows KO percentage when using DI and using their special move for momentum canceling, if any.

If a character does not have a special move that negates momentum, their statistics in the columns that involve "Special MC" are displayed in grey, as they are identical to their corresponding statistics in those that involve "Basic MC". Also note that Lucario's fair is most beneficial when used in basic momentum canceling with no DI, but his dair is most beneficial when used in momentum canceling with DI. As such, his dair appears in the position of other characters' '"Special Moves".

* Indicates that the character does not make it back to the stage, and is KOd by the bottom blast line.

** Indicates that without DI, the character's special move provides no additional benefit.

Special Moves

This is a detail description on each of the special moves that aid with momentum canceling.

• Spinning Kong: Overall the second best momentum canceling move in the game, it completely negates all horizontal momentum upon the 1st frame of activation. This, combined with DK's fast bair and his great weight, allows him to greatly out survive every other character in the game when knockbacked horizontally, including Bowser. It does not negate vertical momentum however, which is why it is second to Oil Panic. It also leaves DK vulnerable upon return due to its landing lag, but DK will always make it back to the stage while on a neutral stage due to its great horizontal distance.
• Monkey Flip: Diddy Kong's special moderately negates horizontal momentum. Overall, it can be considered one of the best momentum canceling specials since it doesn't put Diddy Kong in a helpless state and it negates a decent amount of horizontal momentum. This allows Diddy Kong to take horizontal hits quite well.
• Egg Roll: Overall this has the third best momentum canceling abilities among special moves. It negates a large amount of horizontal momentum and it allows Yoshi to survive a potentially fatal blow if its first few frames are activated. It is also the only special move other than Oil Panic that can negate vertical momentum as well. However, it has huge drawbacks that make it rather impractical. While the move almost completely negates horizontal momentum, Yoshi gains no horizontal distance while performing it, it takes a while for Yoshi to end it, and Yoshi becomes helpless upon completion. Yoshi will never make it back to the stage while on a neutral stage even with his great air speed. As for vertical momentum canceling, Yoshi can survive longer through the basic method. Overall, this move only has its uses in stages with no cliffs or stages where the blast line is close to the edge.
• Flame Choke: An move that can negate horizontal momentum slightly. In neutral stages, Ganondorf will never make it back to the stage using this move on a non-DI horizontal hit. He can make back on a DI hit in some stages (he won't make it back in Final Destination). Overall, this move isn't very useful for momentum canceling since it only provides a minimal benefit and Ganondorf is very likely to not make it back to the stage. Even if he can make it back, he will be helpless and is essentially a sitting duck for edgeguarders due to his large size and slow air speed.
• Flip Jump: Like Diddy Kong's Monkey Flip, this move can negate horizontal momentum without putting Zero Suit Samus in a helpless state. However, it negates less momentum than Diddy Kong's and only provides a very slight benefit over the basic method. But it is practical as it only provides benefit as it won't put Zero Suit Samus in harms way or impede her recovery.
• Squall Hammer: This move can slightly negate horizontal momentum. The Ice Climbers can make it back to the stage when together, but a solo Climber will not. This move does put them in a helpless state and leaves them vulnerable upon return.
• Arm Rotor: This move negates horizontal momentum very slightly and only has a very minimal benefit. However, it doesn't move R.O.B. far or put him in a helpless state, so it only provides benefit.
• Drill Rush: When combined with the fastest aerial in the game (Meta Knight's uair), this move negates a substantial amount of horizontal momentum on non DI hits (only DK's provides a better benefit). However, this move is significantly less effective on DI hits (while using this maneuver, MK only survives 4% more on DI hits). Also, this move puts MK in a helpless state which leaves him vulnerable, especially due to his very slow air speed, further limiting its effectiveness.
• Super Dedede Jump: This move can surprisingly negate horizontal momentum quite well, despite its mostly vertical movement. On non-DI hits, Dedede will not make it back to the stage on neutral stages. He can make it back on DI hits, though it may require canceling the move at the precise time to grab the edge. Due to its fast movement, Dedede isn't as vulnerable as other characters upon performing this, especially if the opponent is taunting because they believe they gotten a KO. However, performing this move is still risky as using it on a non-DI hit will prove fatal or using it on a what would of been a nonlethal blow could end up with fatal results.
• Skull Bash: This move moderately negates horizontal momentum with the added benefit of not leaving Pikachu helpless. However, this move has a large amount of ending lag so using on a nonlethal blow could leave Pikachu close the stage and vulnerable to a reactive opponent. This move is still safer than most momentum canceling moves though.
• Quick Attack: This move negates horizontal momentum exactly as well as Skull Bash but is inferior for this task as it leaves Pikachu helpless. It is interesting to note that Pikachu is the only character with two special moves that provide a bigger benefit to momentum canceling than the basic method.
• Pound: This move is one of three moves that provides no benefit on non-DI hits but aid on DI hits. Its effect is minimal, but it doesn't leave Jigglypuff helpless so it only provides benefit.
• Quick Draw: This move is one of three moves that provides no benefit on non-DI hits but aid on DI hits. Unlike the other two, it negates a large amount of horizontal momentum on DI hits. Also unlike the other two, it leaves Ike helpless and very vulnerable. While it supplies a large benefit on DI hits, this maneuver is very risky and difficult to pull off. If used on a non-DI hit, the results will be fatal. Also, Ike has to use an air dodge for maximum benefit, which requires different timing and faster reflexes than aerial attacks to use successfully (this is due to air dodges being able and needing to be used sooner in knockback than aerials).
• Spin Charge: This move is one of three moves that provides no benefit on non-DI hits but aid on DI hits. Its effect is minimal on DI hits like Pound. Unlike Pound, this move will bring Sonic back to the stage so it has some risk. But it doesn't leave Sonic helpless and its fast so its overall risk is minimal.
• Oil Panic: The best momentum canceling move in the game, it even has its own special name, being called "Bucket Braking". This move completely negates all momentum starting on frame 1, both horizontal and vertical. As long as Mr. Game & Watch can get the bucket out, he will completely stop, preventing a would-be fatal blow. This move also has no risk as it doesn't leave Game & Watch helpless or move him at all, preventing him from being attacked while using Oil Panic. Overall, this is a technique that is essential for Game & Watch players to learn. It should be noted that using Oil Panic while the bucket is full will not aid with momentum canceling at all.
