Fox- Fox's blaster is alright in Brawl. Not as good as Melee, but alright. This makes the projectile battle in Toon Link's advantage. Your projectiles stun, his don't. Because of how fast his Blaster fires, he's likely to get a few hits off. Don't fret though, these hits only do between 1-3 damage. Your projectiles, in addition to doing more damage, stun him, and will eventually force him to approach. If he begins shooting stationary lasers, remember to attack from above with your projectiles. Although you win the projectile war...Does that mean you win the camping war? A difficult question to ask, since there is one move Fox has that completely renders your projectiles useless: Shine. Fox's down B, or Reflector, or Shine, reflects back your projectiles. Will most Fox's use this from long range while you are spamming them? It depends. If you are playing smart and avoiding lasers while attacking with projectiles, then yes. Theoretically, they can just wait in the Shine all day while you throw projectiles and have them reflected back at you. However, this will almost never be the case.
Instead of focusing on trying to outcamp Fox with your projectiles, position yourself in mid range. This is where you can really take the pain to Fox, as he is basically forced to approach you. He can't laser you, because if he tries, all you need to do hit him with your own projectiles while he is in the air. If he tries to shine them back at you...Be smart, bait it. His Shine takes a while to get out of, so use that opportunity to attack him. It won't be easy though. Fox's lasers are quick, and combined with his Shine, you just may find it too hard to try and time projectiles/worry about his Shine etc...That's when the battle gets taken up close. Who wins the up close game? It's close, but Toon Link does. There is one general rule to keep in mind when fighting Fox. Do not let him get on top of you. Fox can easily combo any character using a combination of his drill, utilt, smash attacks and shine. To combat this, retreating aerials will be your best friend here, along with a more...unorthodox type of defense. Forward Smash. Your Forward Smash will help immensely here, for one huge reason: Fox can't approach.
His approaches are garbage, with only his Dair, which is alright, his grab, which is avoidable/nothing to worry about if he gets it off, and his Nair, which has no range. Fox's dair will be used to try and start a combo, his grab will be used due to Fox's fast running speed, resulting in good dash grabs, and his Nair will be used because it autocancels, meaning if he lands after/in the middle of a Nair, he can immediately use another attack. That means, if he hits your shield with it, don't let go of your shield, just roll away. If he misses with it, don't run in to punish it, unless it's with something that outranges him like your hookshot grab. Back to Forward Smash. Fox's approaches have no range, priority, and each one of them is easily avoided due to Fox's horrible DI and lack of spacing tools. Use your Fsmash when he gets close. Toon Link leans in when he Fsmashes, so it has incredible range. This should stop all of Fox's approaches if spaced properly. Like I mentioned, it's not like he can attack in the air, then DI away to avoid an Fsmash...It's not like he can outrange your Fsmash. Simply put, if he approaches and you Fsmash, you have him trapped. If he catches on and starts dashing and shielding, then don't use the second hit of your Fsmash. It's safe. Be wary of his Dash Attack also, which can lead into a combo, but again is easily taken care of with the strategies discussed above.
Basically, you're going to want to stay mid range against Fox, making it so he can't laser you or do much against your projectiles without fear of being punished. When you get close enough, camp him mid range using retreating aerials and Forward Smashes to punish any thoughts he has of getting close to you. This is a tactic used commonly by Marth in Brawl, mid range camping. Toon Link can do it also, perhaps not as well, but the option is still there, and it's clutch in several matchups, including this one. It's common sense really. If a character cannot approach you safely due to being outranged and a lack of safe approaches...Just make sure he can't approach safely, and punish when he does. Now, to kill Fox. If you want to get technical and talk percentages, Fox can normally kill Toon Link quicker than the other way around, despite Fox being the 7th lightest character in the game. His Usmash is deadly, be careful of it.
However, technicalities aren't always the way to judge things, especially not in a game as deep and unpredictable as Smash. Fox shouldn't be racking up damage on you. If you've camped him mid range, you should stay safe and, for the most part, out of harm's way, save a few lasers here and there and maybe a grab once in a while. Fox can be killed many ways. He dies at low percents due to his light weight. Fsmash works amazing in this match up as a kill move, especially since you'll be using it as a spacing tool anyways. Also, Toon Link's aerials have nice knockback, so at around the mid to high 100's, your aerials can do the trick. Basically, Fox will die on his own due to trying to approach you and being camped mid range.
To edgeguard Fox with Toon Link is easy. Fox has 3 useful options to recover. First, he can use his Illusion, or side B to grab the ledge. Next, he can use his Illusion to come back onto the stage. Lastly, he can use his Foxfire, or up B, which they will almost never use unless forced to. Going back to basic strategy, you're going to want to cover as many options as possible. Here's how you do it. Throw either a boomerang, or, preferably if you can time it right, an arrow off of the edge. This covers his option to Illusion back to the stage. If he tries, he will get hit by your arrow/boomerang and fall down, forcing him to Foxfire. After you throw your projectile of choice, quickly edgehug. This covers his option to Illusion to the ledge, as if he tries, he will fall to his death. Now, if your projectiles hit him while he was trying to Illusion to the stage, all you need to do is let go of the ledge, DI towards Fox, and either Nair him or even Dair him. It takes some practice to get down, so practice it as much as possible until you become comfortable with it. You'll have to throw your projectile as soon as you throw/hit Fox off the ledge, so Fox has less time to recover. Also, this is not guaranteed to work 100% of the time, as if they catch on, they can just Foxfire or Illusion way above you and onto the stage to avoid the gimp. This is commonly avoided since they are left defenseless if they recover onto the stage, and you should punish it accordingly.
Basically, it's a battle of spacing against Fox, one that he loses horribly. I don't think this matchup is too much in Toon Link's favor, as Fox is pretty fast, and is likely to get some hits in if you mess up. His Usmash kills at early percents, to be exact, on Final Destination with no DI, it kills Toon Link at 90%. Yeah, stay away from his Usmash. He can combo you until between 30 and 40 percent if you're not careful. So, Fox has the ability to kill you early, and also deal some damage if he gets into your range. Toon Link has the ability to keep Fox away by smart projectile use, and mid range camping. He can kill Fox at early percents also, even if it isn't as early as Fox can kill him. Toon Link can gimp Fox's recover pretty hard, so he should die a roughly estimated 1/3 times he is off of the stage. Remember, Fox can kill you early...But he shouldn't be able to touch you. That's the key. As Isai's famous advice goes, "Don't get hit." It shouldn't be that hard to do, due to Toon Link's ability to obliterate Fox's horrible approaches. I rate this match 6/10 in Toon Link's favor.
