Ripple, try to update the 1st post with the Fox data.
I guess next is Wario. I've never really had any problems with Wario in singles because I've never played one that can do the chaingrab all the way. I'd assume if I did fight one who could do it to 110%, the match would definitely be very difficult.
Chaingrab aside, Wario is very good at camping. Even though he doesn't have a projectile, his air camping game can really become annoying if you don't know how to handle it. All of Wario's aerials are good. That's mainly due to the fact that they can be used to approach safely due to his floatiness and that he can actually kill with 3 out of 5 of his arials: the uair, the dair, and the bair. I believe they are in the correct order from best to worse in terms of killing at lower percents.
He will approach mainly with dair's because he can manuever it around your shield because of his aerial mobility. Don't assume that he will always approach you this way because he can pop in and out with fair and bair and escape a counterattack if he's good. Nair has so little knockback that it can be used to set up combos. Actually, he can use all his aerials to set up combos. With DK being the way he is in terms of size, we will eventually get comboed.
Our bair and up angled f-tilt can easily swat down Wario with good spacing and timing. Our grab game with Wario is also beast because we can kill Wario from a grab at decent percent. Since Wario is cursed with bad aerial release frames, we can grab Wario at 90% and grab release him into a sliding up smash (and I believe a aerial Giant Punch). Normal approaching (bair, f-tilt, d-tilt, grounded up b) can be used on Wario with minimal threat, so you don't need to play so gay like you would with Olimar or Dedede. Just try not to get grabbed just in case of the chaingrab. Also, Bite can be annoying at times too because it can absorb a hit with super armor and suck you in. A couple f-tilts approaches can lead to decent damage from Wario with Bite.
Beware of Wario's killing potential because its almost as beast as ours. F-Smash and uair will be the two major kill moves you need to look out for, f-smash especially because it does have super armor (not exactly sure on what frames). F-tilt and the fart are going to be your next moves to watch out for. F-tilt can kill you at 130% at the edge if you don't expect it and the fart after a minute can catch you by surprise. A fully charged fart will start making you think twice about approaching at times (think about how other characters play against us when we have a Giant Punch charged). Also, Wario could edgeguard us pretty well if you aren't skilled enough to get around his aerials.
Personally, I think this matchup is 55:45 in Wario's favor. Add the chaingrab to the equation, I'd go with 60:40 in Wario's favor.
