Standard Air Attack

The Neutral Air Attack is an attack used by all characters in the Super Smash Bros. series. This is an attack performed in the air while not facing in any direction, similar to a neutral special B move. A Neutral Air Attack is commenced by jumping once or twice and then pressing the attack button when not moving up, sidewards, backwards or downwards. Samus, Zero Suit Samus, Ridley and Dark Samus each have their own Neutral Air Attacks.

Samus's Neutral Air, the "Chozo Kick", is a forward midair "sex" kick, angled slightly upwards. The longer the kick is extended, the weaker its power will be. It deals 16% damage with a clean hit, and only 13% if late. (Super Smash Bros.) In Super Smash Bros. Melee, it deals less damage (14% clean, 10% late) but has good knockbac. Due to Samus's long legs, the attack is considered to be one of the best kicks in the game, capable of KO'ing opponents under 150%. However, the move is nerfed in Super Smash Bros. Brawl, dealing 9% clean and 6% late and with reduced knockback.

In Super Smash Bros. for Nintendo 3DS and Wii U, Samus has a new Neutral Air Attack. It is a spinning roundhouse kick that hits thrice, deals more damage, has more knockback, increased range behind Samus and launches opponents at a more horizontal angle. It deals 10% on the first hit, and then one percentage less for the two subsequent hits. Update 1.1.5 to the game increased its power to make it one of the strongest Neutral Air Attacks in the game.

While unconfirmed, it is likely that Dark Samus's Neutral Air Attack will be identical or very similar to Samus's.

Zero Suit Samus's Neutral Air Attack involves the Plasma Whip. In midair, Zero Suit Samus spins the whip around herself. While it has reasonable range, it always deals 10% damage, launches at 55° and has below average knockback. In Super Smash Bros. for Nintendo 3DS and Wii U, the attack deals two percentage points less (8%) after update 1.1.5, but has somewhat increased knockback.

Ridley's Neutral Air Attack resembles a backwards version of Charizard's, where Ridley does a complete flip in air, hitting enemies multiple times. The move has a sweetspot on the tip of his tail. It deals up to 12% base damage, with a sourspot closer to his body dealing 4 or 5% damage.
