Up aerial

An up aerial (, Up/above/upper midair attack; commonly abbreviated as Uair or u-air, and referred to as AttackAirHi internally) is an aerial attack that is performed in midair by pressing the attack button while tilting the control stick upward. Its official term varies between titles; it is known as an up midair attack in Super Smash Bros. Melee, and an up air attack from Super Smash Bros. Brawl onward. Many up aerials either have a wide coverage above the user, such as flip kicks, or are narrow but powerful strikes directly above the character's head. They also tend to launch the opponent at a predominantly upward angle, making them crucial for juggling. Many up aerials have a landing animation involving the character falling on their back and having to get back up.

==Notable up aerials==
*Mega Man's up aerial, as well as 's in Ultimate, are the only up aerials in the series to be projectiles, allowing them to be reflected or Pocketed.
**Mega Man's is known for its ability to deal over 20% damage if all hits connect, as well as being composed of windboxes that push opponents upward, allowing it to juggle them efficiently and KO them near the upper blast line, especially if they attempt to jump out of it.
**It can also meteor smash opponents if it's reflected.
* and 's up aerials function as tether recoveries.
*Captain Falcon's up aerial is one of his most useful moves in each of his appearances. In Melee and Brawl, it is used as an aerial spacing tool because of its long-range, and can KO at fairly high percents. In Smash 64, Smash 4, and Ultimate, it is used as a juggling tool to string multiple up aerials together and finish off with another move (most infamously Falcon Dive in Smash 64, commonly known as the Stairway to Heaven.). It can also be used as a rather powerful edgeguarding tool in Smash 64.
*'s up aerial in Melee is known for its deadly power, being the second strongest up aerial in the game, only behind 's. It can KO most opponents under 100% from ground level, and can be comboed into from his up throw at a wide range of percents, including at high percents as a KO setup. It was slightly less powerful in Smash 64 although it had better combo potential, especially the first hit. While its knockback was greatly reduced from Brawl onward, it remains a powerful finisher, KOing under 150% from ground level.
*'s up aerial in Melee is the strongest up aerial, as well as one of the strongest aerials overall, although it has extremely high startup lag to compensate. Its power was reduced in Brawl (and reduced again in Smash 4) although it has noticeably less startup lag (which was reduced even further in Smash 4).
**In Smash 64 the strongest up aerial was ' up aerial in the Japanese version and 's in the international versions.
**From Brawl onward, this is the case for Zelda's up aerial instead which is particularly powerful in Brawl.
* has the only up aerial in Melee that cannot be L-canceled, due to being coded as a special move. This oddity is also present in his neutral aerial and back aerial. It is also the only aerial move where his appearance changes in Ultimate.
*'s up aerial in Brawl is infamous for its range, juggling ability, and extreme speed (coming out on frame 2 and taking only 13 frames to finish), allowing it to true combo into itself even at tumble percents with Brawls hitstun canceling. Prior to the introduction of , it was the fastest aerial attack in the entire series. It remains the fastest aerial in terms of startup lag, as Steve's comes out on frame 4 and takes 11 frames to finish, assuming Steve has gold tools.
**In Smash 4, it has been significantly nerfed, although, in combination with the changes to hitstun canceling, it can still combo into itself multiple times and then into Shuttle Loop, which easily KOs opponents near the upper blast line.
*'s up aerial in Smash 4 is widely considered one of the best due to Luma's very fast startup (the lowest out of every up aerial in the game) and high base knockback, as well as Rosalina's large disjointed hitbox, which can be used in conjunction to combo into itself and as a followup from several other moves. Most infamously, with high rage, it can drag opponents to the upper blast line and KO them at extremely low percents. In Ultimate, it has been noticeably nerfed, with Luma's attack having more startup, and both characters' attacks having more ending lag to the point there are no longer any followups out of them, in addition to the effect of rage itself being weakened.
*'s up aerial in Smash 4 is often considered one of the best due to its speed, power, juggling ability, low landing lag, immediate auto-cancel after the hitboxes cease, and deceptively long range both vertically and horizontally, making it a powerful juggling option with little commitment and allowing it to start combos on grounded opponents. In Ultimate, it is much harder to use consistently, as it auto-cancels later, has less range especially vertically, and its power has been decreased, although it remains a solid anti-air option.
*Zero Suit Samus's up aerial in Smash 4 is notorious for setting up ladder combos. It can combo into itself at low to mid percent to drag opponents near the upper blast line and combo into Boost Kick for an early KO. It can even be done with the aid of platforms. While the move has a bit more ending lag in Ultimate, she can still pull it off depending on the hitbox placement she hits with.
**It is also one of her best moves in Brawl. Compared to its later incarnations, it has faster startup (frame 4 instead of frame 6) and has significantly more KO power due to its higher damage and knockback. Additionally, it is notorious for possessing a large disjointed hitbox on its clean hit (although its clean hit has three active frames, the sizable disjoint is only active for one). Despite not having as much combo potential as it does in later games, it is still a very potent combo and juggle tool overall, and is one of the best aerials in the game. 
**Mario's up aerial in Smash 4 and Ultimate (and Smash 64 to a lesser extent) is similar to ZSS's, easily setting up ladder combos into itself at low to mid percents, due to its combination of low lag all around and wide coverage above him. With the aid of platforms (such as those of ), these combos can be extended to drag opponents near the upper blast line and combo into Super Jump Punch for a KO.
*King K. Rool's up aerial has him perform a small leap that halts his momentum and stalls him in the air. Additionally, it provides head intangibility and Belly Super Armor, making it extremely well protected during startup, on top of being a powerful KO option. Its peculiar stalling properties uniquely assist K. Rool in recovering and "stealing" platforms, however this is counteracted by its extremely high ending lag, the longest of any aerial attack in Ultimate.
*'s up aerial in Ultimate is incredibly fast and easily combos into itself or other aerials. It is also the only up aerial in the game that can be repeated by holding down the attack button, and is comparable to his up tilt.
*'s up aerial in Ultimate has notably immense range, far surpassing that of every other up aerial in the game.
*Ryu and Little Mac are the only characters with a up aerial that involves punching, and both are one of only three up aerials that involves attacking solely with an arm, with the other being Jigglypuff's up aerial. R.O.B’s up aerial also involves his arms though he flails them instead.
