So I've been talking about this secret technique of mine that I found out about last week, it's an Instant KO trick that the Mii Brawler can perform with his Piston Punch Custom Up B. As of right now I do not have any video to show you, but I will update this front post later as I have performed it in tournament on live stream. Once the video gets posted to youtube I will post it here.EDIT: Here is a demo that SC2_Bench on Reddit uploaded demonstrating the trick, so courtesy to him for doing this. It's pretty much the same thing I do.Anyways, let me explain it to you.Mii Brawler's Piston Punch has a strange hitbox on the 1st hit of it. It's a set knockback, meaning regardless of percent, the opponents will always fly the same distance. For some reason, Brawler's Piston punch's 1st hit has an insane amount of set knockback for absolutely no reason at all, its supposed to combo into the rest of his up b, but if the 2nd punch misses, ZOOM! Off the opponent goes, flying off the top and dying at any percent, even 0%.To pull this off you must simply do a d-throw or an u-throw into his up b. (To clear some confusion, yes, you do have to short hop, jump, or double jump to space yourself correctly depending on the situation) Though it has to be spaced correctly that the opponent is about 1-inch above you, like close enough that you could almost land Jigglypuff's rest with it, but not close enough. This will allow the 1st hit to hit and the 2nd to miss. D-throw into the one inch punch is a true combo, however, the U-throw to the One Inch punch is not, but they MUST air dodge to avoid this, use this to your advantage and you can easily bait out their airdodge and punish with anything you want. It's incredibly crazy.Now, for who this works on, its heavily based on Weight Rankings, as heavier characters such as Bowser, DDD, Ganon, it will not work on, while lighter characters such as Jigglypuff, Rosalina, G&W, it is incredibly easy. Here is a list of weights.Because this is a set knockback, this will kill opponents depending on what level you do this at, including on platforms, whether you did d-throw or u-throw, or what the opponents percent is, its a lot to take into consideration, so I hope others help me with this lab time and figure out when everyone will die from these attacks. This is what I've collected so far.These are when characters will instantly die from getting hit by the One Inch Punch. Some of these might be slightly inaccurate, but I assure you it works. (Vectoring and DI are not taken into account yet)Jigglypuff - D-throw at 0% Any stageRosalina (and everyone lighter) - U-throw on Ground Level of Yoshi's Island at 0%- D-throw on Ground Level on Yoshi's Island at 30%- D-throw on YI's Platform at 0%Lucario (and everyone Lighter) - U-throw on YI's Platform at 0%D-throw on YI's Platform at 50%Shulk (and everyone Lighter) - U-throw on the Top Platform of BF, 0%Bowser (and everyone Lighter) - U-throw on the Highest Platform on Prisim Tower, at 0%.Yeah, its incredibly crazy and this is just simply the start. I do hope to get my videos up here soon demonstrating it, but if you have any questions and would like to contribute to this, that would be the best! This is an incredibly huge find and will change the way Brawler is played for sure.
