Wolf's back aerial in Super Smash Bros. Brawl.

Olimar's back aerial in Super Smash Bros. for Wii U.

The back aerial attack (abbreviated as bair, B-Air, or ABA, and referred to as AttackAirB in internal Brawl files) is an aerial attack that can be performed in midair by pressing the attack button and tilting the control stick or d-pad in the direction opposite to which the character is facing. Its official term varies between titles, where it is known as a "back midair attack" in Melee, and a "back air attack" in Brawl. The majority of these attacks are kicks.

List of back aerials in Super Smash Bros.

In general, back aerial attacks in Super Smash Bros. are slow but with good range and good knockback. All except Link's are one-hit moves:

Character	Description	Damage
Captain Falcon	Punches backward with one hand. More of an advanced comboing move compared to his other aerials, more difficult to use in combos but overall better than up aerial against floaty characters.	16%
Donkey Kong	Kicks opponent with both feet. Too slow to be overly useful, but good for comboing against wall.	15%
Fox	Kicks opponent with one foot. Yet another good aerial for Fox, good for edgeguarding Falcon's and Samus's among others.	12%
Jigglypuff	Kicks opponent with one foot. An overall good move if it had more range, very quick, low power, virtually useless at low percents, can combo into itself at mid-percents.	13%
Kirby	Kicks opponent with both feet. The best example of a wall of pain move of SSB, good damage + good for combos, great edgeguard tool.	16%
Link	Kicks feet behind him one at a time. Very quick move usually used for combos, more of a backwards double kick. Good in almost all circumstances and overall Link's most useful aerial for comboing.	15% if both hits connect.
Luigi	Kicks opponent with both feet. Good range but slow, similar to Mario's but with more range and less speed.	16%
Mario	Kicks with both feet. Good KOing move, similar to Luigi's but with less range and more speed.	16%
Ness	Kicks opponent with both feet.	16%
Pikachu	Kicks the opponent behind it. The move is usually used either to start or finish a combo or to edgeguard.	16%
Samus	Raises her foot and then thrusts it behind her. Samus' overall best move. Huge range and power and Samus' main KOing/spacing move.	14%
Yoshi	Kicks opponent with both feet. Yoshi's overall slowest DJC aerial, good after up tilts, leads into other DJC aerials.	16%

List of back air attacks in Super Smash Bros. Brawl

Character	Description	Damage
Bowser	Forces his shell backwards.	15% clean, 7% late.
Captain Falcon	Does a quick backhand.	14%
Charizard	Spins around surprisingly quickly with tail extended and wings slightly extended. 2 possible hits, one with wings and one with tail. Decent knockback on tail hit, wing hit will always link into tail hit. Wing hit meteor smashes, but this is only to lead into the second hit. Has a sweetspot on the fire, but it's hard to sweetspot as it has a small size.	16% when all hits connect and sweetspotted.
Diddy Kong	A fast turnaround motion with his leg stuck out.	9%
Donkey Kong	A simple backwards kick. Moderately long duration, great range and powerful.	13% clean, 8% late.
Falco	Kicks backwards, similar to Fox, but with less knockback and is a sex kick.	13% first frames, 9% later frames.
Fox	A standard kick, Fox spins with his leg outstretched. It has some ending lag in the air, but can be used as a KO move.	15%
Ganondorf	Punches backward. Very similar to Captain Falcon's, but instead of having a long duration, it has a large hitbox with a large sweetspot but fairly long landing lag.	16%
Ice Climbers	Spin around with hammers slightly extended. Deceptively powerful.	Leader, 11%. Partner, 8%. Total, 8-19%
Ike	A quick spin with sword extended. Powerful, can be auto canceled in short hops (it misses against smaller characters) and very fast start-up, but it has a very long cooldown like all of his aerials and moveset in general.	14%
Ivysaur	Spins around with vines extended. Low damage and very low knockback, but excellent range.	5% damage if both hits connect.
Jigglypuff	Spins around with foot extended to about twice its regular size. Used for the wall of pain.	12%
King Dedede	Similar to Kirby's, but with one foot. It has a large hitbox, with disjoint during the first frames of the move. Generally considered one of the best back aerials in the game.	13% first frames, 9% later frames.
Kirby	Extends both feet backwards. Used for Fence of Pain. Often considered the best move in Kirby's arsenal.	12% first frames. 9% later frames.

Lucario	Punches backwards. Aura extends from palm.	8% at minimum power and 16% at maximum power.

Mario	A twizzle-kick of sorts, he kicks behind himself with both feet and spins.	12% clean, 7% late.
Marth	Similar to Toon Link's in animation, Marth thrusts his sword upwards. However, this attack is notable because it turns him around. When tipped, this attack can KO around 150%.	11% untipped, 14% tipped.
Meta Knight	Slashes three times behind himself very quickly, slightly slower/more powerful than his forward aerial, which has the same properties.	10% if all hits connect.
Mr. Game & Watch	Snapping Turtle, hits multiple times with good range; however, it can be SDIed out of and be punished before the move has ended. Eats through shields. Last hit can be powershielded, but is very difficult to perform.	15% if all hits connect.
Ness	Plugs backwards with both heels. Initial hitbox quite powerful with electrical properties, second hitbox fairly weak, although buffed from Melee. It is a very powerful move, and one of Ness's best KO moves.	15% sweetspotted, 8% sourspotted.
Olimar	Swings a Pikmin backward.	Red: 13%, Blue: 13%, Yellow: 12%, White: 5%, Purple: 13%.

Large duration and high knockback (although it deals the same damage, his body has slightly more knockback than his legs), but has a fairly long cooldown and 30 frames landing lag. Doesn't auto cancel in short hops. Large range and disjointed hitbox.	Does 16% when sweetspotted, 14% sourspotted, 10% if the later hitbox is landed.

Notable back aerials

Dr. Mario's back aerial attack in Melee. It is a semi-spike.

• Jigglypuff's back aerial in Super Smash Bros. Melee, Brawl, and Smash 4 is used for the highly effective "wall of pain".
• R.O.B.'s back aerial propels him forward, and forward while traveling diagonally upward when using Robo Burner.
• Peach's back aerial has almost no landing lag, even less than its standard midair ending lag.
• Kirby's back aerial in Melee, an attack similar to Jigglypuff's back aerial but instead has almost no start-up lag. The move is dubbed the "fence of pain".
• Marth, Lucina, and Roy's back aerials allow them to turn around while still in midair. These are the only aerials able to do so in the Super Smash Bros. series.
• Dr. Mario's back aerial is a semi-spike with high base knockback, making it effective for edgeguarding.
• Ness and Zelda's back aerials in Melee, are powerful semi-spikes. Zelda's back aerial semi-spike can only be achieved from a hit with the sweetspot at her toe, while Ness's has to be hit in the intial frames to be powerful.
• Ganondorf's back aerial in Super Smash Bros. Melee is known for its tremendous range, duration, and a knockback only bested by Zelda's Lightning Kick. Such attributes make it one of, if not, the best back aerial in Melee overall.
• Toon Link's quick back aerial, with minimal knockback in Brawl. The move is effective for positioning the opponent for an immediate down aerial.
• Pikachu's back aerial has extremely short range, but the hitbox surrounds Pikachu.
• Mr. Game & Watch's back aerial is the feared Turtle, a disjointed five-hit combo. Like his neutral and up airs, it cannot be L-Canceled due to a programming error in Melee
• Lucas's back aerial is the only one in the entire series to meteor smash.
• Samus's back aerial in Melee, one of her combo moves, which, when sweetspotted, is a very powerful low-percent killer, and when not sweetspotted, is a wall of pain on some fast and medium fallers.
• Lucario's back aerial in Smash 4 when it is in full power and sweetspotted, is very powerful KO moves as it can KO opponents under 50%. It is the most powerful back aerial in the game and is the most powerful aerials in the game.

Reverse Aerial Rush

The Reverse Aerial Rush, often abbreviated the RAR, is a technique in Brawl that allows a character to use a back aerial in front of him or her. This is often used because the character has an inferior forward aerial or that a back air is simply more efficient than a normal attack at the time. It can also be used as an approach option. Many characters, such as King Dedede and Ness, can benefit from this technique.
