Fox (SSBM)/Neutral aerial
Fox does a flying kick, being an easily identifiable sex kick. It has very quick startup, in addition of having decent knockback when it first comes out. With its long duration and extreme speed, it is a good option against shields, and a very good move to be used in a short hop or as an aerial approach. It also helps when an opponent is approaching or near him - combined with Fox's fast falling speed, it's also an excellent move to use in a SHFFL while approaching, as Fox can then lead into other moves easily, such as a waveshine. Overall, it's a move commonly used in Fox's metagame due to its versatility.
