Up aerial

Zelda's up aerial in Melee.

Link's up aerial in Brawl.

An up aerial (abbreviated as uair, UAir, or AUA, and referred to as AttackAirHi internally in Brawl files) is an aerial attack that is performed in midair by pressing the attack button and tilting the control stick or d-pad upwards. It also gains a moderate boost in height if the character's attack is a backflip used just before the apex of the jump, but the user loses their second jump. Its official term varies between titles; it is known as an "up midair attack" in Melee, and an "up air attack" in Brawl. Many up aerials are circle kicks, which have large range and very slightly disjointed hitboxes. They can also send the opponent in diverse directions. A lot of up aerials can be used for air juggling.

A lot of up aerials in Brawl have a landing animation involving the character falling on their back and having to get back up.

List of up aerials in Super Smash Bros.

Character	Description	Damage
Captain Falcon	Does a flip kick. Incredible hitstun and one of the most fearsome moves in the game due to its versatile uses in both combos and edgeguarding. Back of the hit is a very powerful semi-spike.	16%
Donkey Kong	Slaps upward. Using platform cancels, this is DK's main combo move outside of wall combos. Combos into other up airs or up smash.	12%
Fox	Flips then kicks. Has set low knockback with the first hit. Infinites if only the first hit hits. Second hit has great vertical knockback.	15% (total)
Jigglypuff	Slaps upward. Part of Jigglypuff's basic combo of up throw, up smash, up throw, multiple up airs into Rest.	16%
Kirby	Spins rapidly. A very different form of aerial, as it does 2 hits if it isn't Z-canceled and 1 hit if it is. Combos into down air at low percents.	10%
Link	Thrusts his sword up. Good combo move but with poor range. Adequate knockback.	16%
Luigi	Does a flip kick. Combos into the Super Jump Punch and the Luigi Cyclone.	12%
Mario	Similar to Luigi’s but not as useful. Combos into f-air and up smash. The low damage hit of the move can also combo as well into back air.	12%
Ness	Headbutts upward. Good for juggling and DJCing.	15%
Pikachu	Flips and hits opponents with his tail. Its knockback depends on which area of the tail hits. A popular combo move and gimping tool. Has a large disjointed hitbox.	10%
Samus	Does a spin kick upward. Not too useful outside of baiting overly aggressive opponents and reading it into a back air.	10%
Yoshi	Flips while using his tail to do damage. A combo end move with low range preventing it from starting up combos. Incredibly useful out of up tilts against any heavy or medium character using DJC's.	15%

List of up aerials in Super Smash Bros. Melee

Character	Description	Damage
Bowser	A savage upward hit with his head. Very high knockback, but one of Bowser's slower moves. It is the strongest up aerial and one of the strongest aerials in the game (stronger than Ganondorf's dair on grounded opponents).	9-17%
Captain Falcon	A backflip in midair with his feet out. Knockback direction depends on what angle the move hits the foe, though strong nonetheless. Also good for juggling.	13%
Donkey Kong	A headbutt upward, good for juggling fast-fallers.	14%
Dr. Mario	A flip kick upwards, which is good for juggling fast -allers.	10%
Falco	A kick up with his tail extended afterward. A two-hit move. If hit with the center of Falco's body, there is no knockback.	6% (hit 1)/9% (hit 2); 15% total
Fox	A flip kick with extreme vertical knockback and high speed.	17% (two hits)
Ganondorf	One of his most useful and fastest moves, and when used backwards, allows him to knock-out his opponents at low damage due to the semi-spike.	13%
Ice Climbers	Both Ice Climbers point their hammers above their head.	17% (total)
Jigglypuff	Waves its hand up in an arc. Not the best aerial KO move, though excellent for juggling.	17% (total)

Marth	An aerial backflip slash.	13%

Peach	An eccentric kick upwards.	11% (sides)/12% (body)/14% (foot)

Samus	Brings her legs above her body and spins. Several hits.	10% (maximum)
