An aerial attack (空中攻撃, Midair attack) is any move that is performed in midair that is not a grounded attack or special move. Their official terms vary between titles; they are known as midair attacks in Super Smash Bros. Melee, and air attacks in Brawl and Smash 4. Most aerial attacks deal moderate damage (9%-14%). Aerial attacks can be L-cancelled in SSB and Melee.
