Fox (SSB)/Neutral attack
Fox does two quick, generic paw jabs, then a series of rapid kicks. First and second hits deal 4% damage each, while the kicks deal 1% each.
The first hit does extremely little knockback that is noticeable at percentages around 100% and above, but at such percentages, it can be followed up with a variety of moves outside the following hits of the jab, thanks to the hitstun it produces. It can easily lead into an up smash at around 100% to secure a KO (anywhere on the stage), as well as a forward smash at around 120% (anywhere on the stage, but much more effective near the edge), and a down smash at around 90% (near the edge), being an effective way to set up the semi-spike edgeguard. Against floaty characters or characters with close to floaty falling speeds, an up aerial can also be used at around 130% for a KO, as well as a short hopped shine to start some sort of combo. Additionally, at low to high percentages, the move can jab cancel into itself and the second hit repeatedly to rack up damage and/or set up a grab. At percentages just under KO percentages, it can combo the opponent while walking when used repeatedly (in a similar way to a lock in Brawl, but the opponent is under hitstun instead), then lead straight into the usual up smash for a KO. The move isn't easy to land against an opponent playing defensively due to its rather short range (as with most jabs in the game), though if one can land it, it proves to be an effective way to combo straight into a KO move or a move to get the opponent offstage.
The second hit is faster than the first, but it's usefulness is almost nullified by the first hit being more useful in almost every other aspect. Generally, only the first hit is used for combos, though as explained above, the first and second hits can jab cancel into themselves repeatedly to rack up damage and/or set up a grab.
The looping infinite is generally not used competitively, due to being laggy, dealing very minimal damage, being very easy to punish, and having almost no followup options.
