Ryu (SSB4)/Down aerial
Ryu punches diagonally downward in the air relatively quickly. An incredibly useful tool in Ryu's arsenal, this aerial attack offers numerous advantages. When used alone, its sweetspot acts as a rare diagonal meteor smash, though the hitbox to make this happen is rather small. As part of a combo, when used near the floor, it sets up the player for several potential follow-ups, most notably up tilt (tap or hold), up smash, and Shoryuken, each of which are usually difficult for the opponent to escape from.
