Sheik (SSBM)/Forward tilt
From SmashWiki, the Super Smash Bros. wiki
Sheik does a quick round kick in front of herself. Although the move has medium-short range, it is a staple combo move in Sheik's metagame, as it can easily setup forward aerials on fastfallers, and leaves almost any character open for aerial combos, along with having minimal startup and ending lag. It can also be used in between down throws on fastfallers to position them for regrabs or other followups.
