Fox vs Kirby
by t1mmy
Overview
In general Kirby and Fox have similar options and tactics. The main differences between the two characters include speed and options. Fox's fast ground speed and quick vertical movement allow him to cover distances very quickly compared to Kirby. This by itself opens up a lot of strategic options but combined with his Laser and quick-landing attacks, Fox gains even more versatility. Kirby's strength is in his strings, combos, and mix-ups. These strengths gain an even greater boost considering Fox's light weight and penchant for being juggled and gimped.
Long Range
Since Fox has the speed advantage, it's easy for him to set the spacing and tempo of the match. At long range, Kirby has little to nothing to work with, so it is Fox's advantage to be as far away as Lasers will reach. While it's true that Kirby's crouch is low enough to avoid practically any Laser sent at him, the best this form of defense will accomplish is a stalemate. Foxes have also developed techniques to put Laser pressure on a crouching Kirby such as Ledge-hopped Lasers and working with stage transformations/tilting. At any rate it is most common for one combatant or the other to approach.
Mid-Range
Fox's short-ranged attacks get a noticeable boost from his quick dashing and jumping speeds. Because of this, the Mid-range distancing for Kirby is a little further outside what would be Fox's usual pressure zone. This is simply to give Kirby the time to react to anything Fox throws out at Kirby. Most often Fox attacks from above, and since Fox's horizontal movement is not on par with his vertical movement, this will give Kirby plenty of time to react to any aerial offense. Ground-based offense from Fox will come out at a much quicker speed, but aside from his Smash Attacks there's little to be concerned with a Fox on the ground.
Speaking of Smash Attacks, this is the distance at which Kirby will have to be on the lookout for a Dashing Up-Smash from Fox, specifically when Kirby reaches KO percent. Fox's U-smash KO's at 82% without DI (from FD's baseline) and 91% with bland horizontal DI. Fox's U-smash hits as early as frame 8, which combined with his dashing speed makes for a very speedy and deadly finisher.
The good news for Kirby is that Fox leaves himself very vulnerable every time he attempts a U-smash. The reason is because if Fox hits a Shield, Kirby has anywhere from +26 to +33 frame advantage from a regular Shield and +36 to +43 from a Perfect Shield. So while the U-smash can push Kirby away a good distance in his Shield, there's usually enough time to hit out of Shield-Drop with any practical move.
A note to both Fox and Kirby players: if Kirby is camping B-air at this range, Fox can dash in and U-smash the B-air before Kirby can jump out of range or drop to the ground and Shield. If Kirby hits Fox's shield with a well-spaced B-air, Fox has enough time to Shield-Drop and buffer a Dash into a Dashing U-smash (with a 4-frame window of opportunity).
Close-Range
Both Fox and Kirby are competent close-range fighters. Fox is slightly faster than Kirby by 1-frame for Jab, F-tilt, and U-tilt but Kirby's D-tilt hits on frame 4 and Fox's hits on frame 7. U-tilt is favored by both characters as it can launch the opponent into a juggle. Kirby's U-tilt is much better in this match-up since Fox gets juggled much more easily than Kirby, plus Kirby can combo U-tilt into various attacks (usually Grab at lower percents and B-air at higher percents). Fox will generally use his U-tilt to either combo into a Grab or another U-tilt at low percents and will simply use it as a damage builder at mid-percents; at higher percents Fox has better attacks to use.
Kirby is much more likely to use his D-tilt than Fox. It is faster than Fox's, has about as much reach, and has a high likelihood of tripping. If the D-tilt trips at low percents, this usually leads into a Throw combo. If the D-tilt trips at higher percents, this can easily lead to a KO with a F-smash follow-up. Even without a trip, Kirby can use the D-tilt's quick attack to follow up with a surprise Grab or F-tilt.
Fox's Jab is superior to Kirby's if only in speed. While it's only a frame faster, at this speed that's generally enough to win out any speed wars. Both Fox and Kirby can benefit from mixing up close-range attacks with Jabs to keep the opponent off-balance or to keep pressure going.
Fox and Kirby both use F-tilt as a spacing tool at this range. It's main purpose is to strike from a safer distance than Jab would allow yet remain less vulnerable than going for Grabs and Smashes which are easier to predict and punish. The use of the F-tilt on both sides of the fight is about equal with Fox's being slightly faster. The benefit of Kirby's F-tilt in this match is its horizontal knockback which can be enough to put Fox off-stage and in a precarious situation. Fox's F-tilt is simply for damage, pressure, or spacing.
Jump-canceling a Shield is very effective at this range since both fighters can be easily punished out of shield. This includes Jump-canceling into Aerials as well as U-smash; Kirby is apt to Shield-cancel with a Grab as well. Note that at this range if Kirby B-airs Fox's Shield, Fox can immediately Jump Cancel into a U-smash.
Air and Off-stage Game
Kirby's aerial attacks are actually better suited for combos and damage building than Fox's are, except that Fox's amazing ground-to-air movement makes him a hard target. Likewise it can be a risk for Fox to move in for an aerial attack simply because of Kirby's effective attacks and the fact that a quick Shield will beat any Aerial Fox launches. This is why Fox uses his quick movement to keep Kirby guessing as to if and when Fox will move in for an attack from the air or from the ground.
The most effective Aerial Kirby has in this match-up is obviously his B-air. Not only is it reliably quick (hitting on frame 6) it also deals a decent amount of damage (12% sweet-spotted and 9% sour), plus it has decent range. Because of all these reasons, Kirby's B-air tends to stale out quickly doing reduced damage and knockback. Even when stale however, Kirby's B-air is a remarkable tool for getting Fox off-stage.
The off-stage game is obviously in Kirby's favor both in recovery and in edge-guarding. When Kirby is off-stage, Fox will usually resort to shooting lasers from a distance while Kirby floats back to the ledge. If any aggressive edge-guarding comes from Fox's side of things it will usually be close to the ledge where he can make a quick retreat, such as dropping with a Shine or a Ledge-Hopped N-air while returning to the Stage.
Kirby's edge-guarding is effective and versatile against Fox. Against Fox's Illusion, Kirby can quickly Edge Hog if he suspects Fox will go for the Ledge, or he can intercept the Illusion on-stage with Smash Attacks, Hammers, and Stones. As long as his prediction is correct, Kirby has the opportunity to land very powerful attacks on Fox - and even if Fox avoids these attacks he's often not in a position to punish them. Kirby can also take the strategy of staying on stage and sending out a Final Cutter Shot to intercept any jumps, Illusions, or Fire Foxes that cross its path. Hitting any one of these with a Cutter Shot moves Fox from a bad position into an even worse position to recover.
KO Options
Both characters have powerful KO options. Kirby has a wider array of strong attacks, but they're all slow and exceptionally easy to punish. The weight of each character doesn't come into play much, although Fox is noticeably harder to Star KO than Kirby is; the majority of Fox's KOs on Kirby will be vertical and the majority of Kirby's KOs on Fox will be horizontal. In general both characters must take care not throw out KO-attacks recklessly since they're easy to punish.
Summary
This match-up is very dependent on player knowledge, spacing, and effective punishment. The advantages and disadvantages also fluctuates based on the Stage selected with short ceilings and camp-friendly stages helping Fox and smaller stages with shorter horizontal boundaries helping Kirby. Speed combined with lasers and a swift U-smash are Fox's greatest advantages, and Kirby's close-ranged attacks and off-stage prowess are his. This all points to a
fairly even match-up.
