Sonic's down aerial in Super Smash Bros. for Wii U.
Lucario's down aerial in Brawl.
Mario's down aerial in Melee.

The down aerial (下空中攻撃, Down/lower/under midair attack; commonly abbreviated as Dair or d-air, and referred to as AttackAirLw internally) is an aerial attack that is performed in midair by pressing the attack button and tilting the control stick downward. Its official term varies between titles, where it is known as a down midair attack in Super Smash Bros. Melee, and a down air attack from Super Smash Bros. Brawl onward. Many of these moves are meteor smashes, and some of these moves can be either stall-then-falls or multi-hit attacks.

List of down aerials

Unless stated otherwise, all down aerials are assumed to have the ability to meteor smash, with most of them requiring a clean hit or sweetspot to be landed.

Notable down aerials

 
Animation of Marth's down aerial in Melee.
  • The down aerials of Bayonetta, Bowser, Corrin, Greninja, Ice Climbers, Mr. Game & Watch, Richter, Ridley, Simon, Sheik, Sonic, Toon Link, and Zero Suit Samus all function as stall-then-falls, except in Melee (and Brawl for Bowser).
  • The down aerials of Link, Toon Link (in Brawl only), and Young Link cause them to bounce a short distance up and away from the opponent upon hitting them or their shield. The hitbox remains active when this happens and he is able to hit the opponent again for extra damage.
    • Similarly, Greninja, Simon, and Richter's down aerials cause them to jump off the opponent upon hitting them or their shield with their down aerials. Unlike the Links' down aerials, these jumps end the move and allow them to perform any action, including combos into other attacks.
  • Mega Man's down aerial is the only one that is a projectile, and thus can be reflected or Pocketed.
  • Lucario, Ivysaur, and R.O.B.'s down aerials stop their movement in the air, unless they were experiencing knockback before their use.
  • In Melee, the down aerials of Captain Falcon, Falco, Fox, and Marth can all spike opponents.
    • Captain Falcon's down aerial possesses a hitbox in his upper body that powerfully spikes opponents, colloquially known as the nipple spike.
    • Falco's down aerial is very fast for a spike (coming out on frame 5), and a vital component to his pillar combos. However, it has been nerfed in the PAL version of the game, as only the clean hit spikes instead of the entire move, making it less effective for edgeguarding and beating crouch canceling.
    • Fox's down aerial is additionally notorious for its use in his waveshine infinite combo.
  • Ganondorf's down aerial is the strongest meteor smash among playable characters in Melee and Brawl, as well as one of the strongest meteor smashes and down aerials as a whole in the series, dealing particularly high damage and enough knockback to KO reliably onstage. In Smash 4, it is one of the only two meteor smashes that cannot be teched on the ground, due to its high amount of freeze frames.
  • Marth's down aerial, specifically in Melee, is possibly the most feared with its speed, range, and ability to spike. Its effectiveness has been reduced in the PAL version, and later in Brawl, where it can be meteor canceled, though it still retains a large part of its utility. In Smash 4, however, it was severely nerfed with reduced range, weaker sourspots, increased startup, meteor smashing only at the middle of the swing, and having a reversed animation (starting from behind Marth rather than in front of him), making it significantly harder to land.
  • Yoshi's down aerial is the most damaging in all of its appearances, dealing a maximum of 56% in SSB, 53% in Melee, 35% in Brawl, 32.2% in Smash 4, and 28% in Ultimate. This allows it to easily bring opponents to KO percentages, especially those with large hurtboxes. Although it deals the least damage in Ultimate, it connects much more reliably than in previous games to its looping hits using the autolink angle.
  • Ivysaur's down aerial in Ultimate is notorious for its large, disjointed hitbox and its ability to consistently meteor smash opponents, making it excellent for edgeguarding.
