Up aerial

Mario's up aerial in Melee.

Zelda's up aerial in Melee.

Link's up aerial in Brawl.

An up aerial (上空中攻撃, Up/above/upper midair attack; commonly abbreviated as uair or U-Air, and referred to as AttackAirHi internally in Melee's Debug Menu and Brawl files) is an aerial attack that is performed in midair by pressing the attack button and tilting the Control Stick 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.

Captain Falcon	Does a bicycle 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%

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. Later changed to his Neutral Air.	10%
Link	Thrusts his sword up. Good combo move but with poor range. Adequate knockback.	16%
Luigi	Does a bicycle kick. Combos into the Super Jump Punch and the Luigi Cyclone.	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%

Notable up aerials

• Fox's up aerial in Melee is known for its deadly power, and is often followed up from his up throw. While its knockback was reduced in Brawl, it remains a very powerful move in both Brawl and SSB4.
• Bowser's up aerial is the most powerful up aerial and one of the strongest aerials in Melee.
• Zelda's up aerial is the most powerful up aerial and one of the strongest aerials in Brawl and SSB4.
• Captain Falcon's up aerial is known for having lots of utility. In Melee and Brawl, it is used as an aerial spacing tool because of its long range, and KOing at fairly high percents. In SSB and Smash 4, it is used as a juggling tool to string multiple up aerials together and finish off with another move (most infamously Falcon Dive in SSB).
• Ganondorf's up aerial is known for being one of the best in Smash 4 due to its incredible versatility. It is a powerful, fast, and generally safe move with a large hitbox that can KO easily at higher percentages. It's good for punishes, protection and edgeguarding, and can be used for combos and jab resets.
• Sonic's up aerial in Smash 4 has a very wide auto-canceling window, making it a very safe move. It is also useful for combos and KOing off the upper blast line.
• Meta Knight's up aerial is known for its speed, range, and juggling ability. It is the fastest up aerial in the series. In Smash 4, it can combo into itself multiple times and then be followed up with Shuttle Loop, which easily KOs opponents near the upper blast line.
• Mega Man's up aerial is known for being able to push opponents into the upper blast line at surprisingly low percentages due to its wind effect, as well as for for juggling. However, because it is a projectile, it can be reflected and will meteor smash Mega Man himself if he is hit by it.
• Ness's up aerial is considered to be one of the best in Smash 4 because of its large hitbox, strength, speed, ability to combo (especially into itself), and its ability to juggle opponents.
• Rosalina and Luma's up aerial is known for being one of the best in Smash 4 due to its disjointed hitbox, high base knockback, and speed. It is used as a juggle and can KO careless opponents at 50% very close to the blast line.
• Shulk's up aerial is the most damaging in Smash 4 when used in Buster mode with Hyper Monado Arts active, dealing 24% if both hits connect. It is additionally part of a 50-50 KO confirm with the Jump Monado Art active, which can KO at a wide percent range based on how the Art is canceled.
• Cloud's up aerial is often considered one of the best in Smash 4 due to its speed, power, juggling ability, low cooldown and deceptively long horizontal range. While its power was nerfed slightly in the 1.1.5 patch, it still remains an effective juggling tool.
• Mario's up aerial in Smash 4 is commonly used as a juggling move, and is often considered one of the most effective ones in the game. If used after a down throw, it can effectively combo into itself at medium percents or higher, which allows it to partake in extended combos with the help of platforms. When successfully stringed on stages such as Battlefield or Dream Land, an opponent can potentially be dragged from 0% to KO percent, where Mario can use Super Jump Punch as a finisher.
