Fox (SSB4)/Back aerial
Fox's back aerial is a back kick that hits straight behind him. It has decently quick startup and generous autocancel windows, to the point that it can be used from the peak of a short hop and still autocancel, making it a safe move for spacing in the neutral. It is a fairly strong semi-spike, making it a decent KO move, as well as his strongest edgeguarding tool. Fox can also use ledge trumps to set up for a back aerial to KO an opponent.
