Up aerial

The up aerial (abbreviated as "uair", "UAir", "u-air" or "AUA") is an aerial attack that is performed in midair by pressing the A 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, where it is known as a "Up Midair Attack" in Super Smash Bros. Melee, and a "Up Air Attack" in Brawl. Many up aerials are circle kicks, which have large range, good priority and very slightly disjointed hitboxes. They can also send the opponent in diverse directions. A lot of up aerials can be used for Juggling.

List of up aerials in SSBB:

Mario: A simple circle kick.

Luigi: Identical to Mario's circle kick.

Peach: An odd kick upwards. Only her foot does damage.

Bowser: Tosses a bite upwards. Looks like a claw swing unless slowed down or paused. A great juggling move.

Donkey Kong: Headbutts upwards.

Diddy Kong: A weak circle kick.

Yoshi: Flips over vertically, doing damage with his tail. Good knockback.

Wario: Claps upwards. Can be used to fly as Wario-Man.

Link: Points his sword upwards. Diverse diagonal knockback.

Zelda: Pulsates an explosion out of her hand. Large, disjointed hitbox, will kill off the top of the stage at low percentages (50% upwards).

Sheik: Spins her body around, with her feet pointing upwards. Sex kick like properties.

Ganondorf: A very quick, powerful circle kick. Can semi-spike.

Toon Link: Identical to Link's.

Samus: Very much like Sheik's. However, the first hits suck the opponent in; only the last hit gives (large) knockback.

Zero Suit Samus: A circle kick. However, it makes a slashing sound when it connects.

Pit: Spins his bow upwards. Diverse horizontal knockback.

Ice Climbers: Point both hammers upwards. Surprisingly high knockback, disjointed hitbox.

R.O.B.: Waves his arms upwards. Multiple hits, diverse knockback.

Captain Olimar: Throws a Pikmin upwards. The Pikmin spins around. Multiple hits.

Fox: A very quick and powerful circle kick.

Falco: Similar to Fox's, but less power.

Wolf: Slashes upwards at a high speed. Lowish knockback, good for combos.

Pikachu: Spins with his tail out for damage. Very low knockback, very low damage, can Semi-spike. If not for semi-spike, would be the worst up aerial in the entire series.

Squirtle: An extremely quick circle kick, but uses his tail instead of his legs.

Ivysaur: Pumps pollen out of his bulb upwards. High knockback, causes Ivysaur to fast fall. Can be used to reduce and negate vertical momentum.

Ness: Headbutts. High knockback, good priority.

Lucas: Similar to Ness' in animation, but with more range, less knockback and less priority.

Snake: A midair handstand. Similar properties to Charizard's. Better knockback.

Sonic: A scissor kick. One of his few KO moves.
