Here is my opinion on the Fox match-up from the weekly discussion thread.
A good Fox will wreck Pac-man's face hard. He is fast, not as much as Sonic, but still dangerously fast. A campy fox is not an issue for Pac-man, it is an aggressive one.
Offensively, Fox has the advantage on his attacks over Pac-man, better grab, better ground game, faster but still potent bair (seriously, auto cancel it a few times, it is ridiculous), superior dair as well. Pac-man has a better fair. They have equal nairs in my opinion. Specials wise, lasers work great to add damage when Pac-man is offstage, they also cancel side b, so a well placed shot and you can be gimped, you need to not be predictable with it. Fruit is much more versatile in this fight, properly using fruit will throw off reflector timing, just be mindful how often you use each fruit. Reflectors I have covered before, just be mindful of the max range of your fruit, and you can still spam them to zone. You must be mindful with hydrant, as it will come back up at you when reflected and follow the same trajectory when launched at Fox. He can safely gimp Trampoline recovery because of his recovery options, so you also need to avoid being predictable with them.
Pac-man cannot reasonably zone out an Offensive Fox, he can weave effectively through trampoline and hydrant spacing because of his ground+aerial speed, with his safe nair. He is able to very safely break hydrant without fear with nair > ftilt (similar to pacman) a fresh bair or down smash. He can also block an aerial hydrant with his up-air or reflector, or worse, reflector > Double Jump cancel on reflect > Uair, limiting it's combo breaker ability. Avoiding follow ups comes down more to airdodge or hydrant change ups.
Pac-man is not at a lost completely however, because of the nature of Fox's attacks, he is very susceptible to nair and fair combo breaking. He can up tilt > Up smash combo Fox at lower percents, but just about anyone can. His recovery, if predictable, is easily gimped (more on that shortly). A whiffed up-smash, while dangerous, can be punished easily with oos options, and tilts. He is easier to kill because of his weight. Pac-man can combo Fox easily because of his fall speed, but you do need to be mindful of nair, it comes out fast. Throw is super risky in this fight because running up smashes basically obliterate Pac-man. Pac-man can punish illusion pretty effectively if used too much with fruit. Fox can also catch some reflected fruit.
I wanted to go more in-depth about the kinds of recovery Fox is capable of Because fox illusion no longer causes special fall, he can use that, with his reflectors ability to stall, up b angles and wall jumps to avoid most of Pac-man's off stage options safely. He can avoid stage spikes because of Firefox's ability to recover underneath most stages. He can reflect and double jump out of reflector when you try to edge guard hydrant attempts, he can illusion through Pac-man, if he tries to offstage fair. While putting himself at risk can reflect oranges then illusion through follow ups. At the same time, if Fox insists on using Illusion to recovery on stage, he can be super easily gimped once he commits with orange, or Side B his landing on stage. You will close out stocks often in this fashion.
Overall I personally feel that Fox is our second toughest match-up. I would definitely put it at 60:40.
