Hey guys. New Smashboards user here.

-Old- How I THINK it works (Sorry, its very hard to do considering I haven't practiced much yet):

Updated Theory:

Inputs for Needle Canceled Attacks:

Grab applications:

(NOTE - THE BELOW GIFS NO LONGER WORK AS WELL IN 1.0.8 DUE TO NEEDLE GLIDE NO LONGER CARRYING MOMENTUM OFF LEDGES. You can still wait until your in the air, but the speed is slower):

(Just input C-Stick > Shield just before you land while needling)

(Note this is different from from traditional wavebounce in inputs, and produces a slightly further bounce in the air. It's [imo] a good bit easier than current wavebouncing methods as well, but it's still definitely worth knowing both):

Inputs for Grounded Wavebounce Cancels:

----------------------------------------------------------------------------Intro-------------------------------------------------------------------------------Glad to be a part of the ninja revolution.Was recommended to move this to it's own thread from the Sheik Compendium of Advanced Techniques, Combos, and Tricks thread so here it is. Guess this isn't my first post any longer ^^Anyways, I was messing around with wave needling... and accidentally instant needle canceled (INC?) into a jab (diagonal c-stick ftw). I then spent forever trying to recreate it (wasn't quite sure what inputs I had used) and finally managed to do it well enough to record it. However curiosity got the best of me, and alas I tried other moves as well... and lo and behold it worked with each. Essentially what this means is that any move can be used at any time while running with whichever direction of momentum and facing you want.-Anyways the Gifs-Note: Further techniques and applications have been discovered throughout the course of this thread, and have been added to this OP.Another Note: Don't give up when trying to practice anything below! The inputs have really strict timing and must all be pressed within very quick succession. It took me probably 2 straight hours of failed practice just to do it once in a blue moon (With enough practice, everything here can be ingrained into muscle memory for near flawless execution mid match).-----------------------------------------------------Tech 1: Instant (7 Frames) Needle Cancels----------------------------------------------Running Reverse DTilt (with reverse momentum):Running Reverse DTilt (with standard momentum):Running DTilt:Running Jab:Running Reverse Jab:Running FTilt (I'm so good at spacing /s):Running Reverse FTilt (has a ton of reach if you space it better than I did):As @ Jaxas has pointed out, it seems you can do any move out of running Needle Cancels.Whats really cool is how Needle Cancelling covers the options that Perfect Pivoting cannot, and vice versa. In neutral standing animation or fox trotting/dash dancing? Perfect Pivots covers pretty much any option with sliding momentum (I think people in general hugely underestimate the usefulness of PPs and Forward Attacking Perfect Pivots [FAPPs... coincidence, I swear]). Already committed to a full run? Instant Needle Cancel into whatever you want in whichever direction you want with momentum. They go together like Peanut Butter and Jelly.This seems to be about as fast as you can Needle Cancel into attacks out of a Dash Dance:I think this takes principals from the Wave Needle, where your needle changes your momentum, and then the shield cancels your needles, but instead buffers an attack in before you actually have the shield input registered.The inputs are really tricky for whatever reason. My new theory is that when you press L (or R) during Needles, instead of L programmed to cast a shield right away, there seems to be a programmed 1-2 frame window of programmed "go back to neutral state so that you can then shield" and THEN shield will come out should you still be holding (Probably seen by developers as an easy way to let Sheik cancel her needles without changing the code for shields in general). I think this is why you can also wave needle without shield ever coming out- you simply let go of shield during this weird window where L acts like a "go to neutral" action rather than "shield". Because this small window of weirdness exists, I'm guessing you can buffer in a move and, if done correctly, the move will go off at the same time as "go to neutral", since it's unlikely they would have added any lag whatsoever to this property of "go to neutral". The end result is you never need to wait for shield or neutral out of needles so long as something is buffered to come out during this window of weirdness.Run > [Let go of left stick for a split second] > hold B (or B-Reverse, I use R as a second special button for this) > C-Stick > Shield> Hold(My) >Note on inputs #1: Make sure to hold down special button until after you press shield. This makes it incredibly more reliable for some reason. If done correctly, you should start an attack 7 frames after your running animationNote on Inputs #2: I might recommend setting your extra shield button (R in my case) to Special Attack, as it feels a bit more natural to press R and L in quick succession than B and L and it allows me to flick the C-Stick to the right for FTilts within the tightly timed execution window much more reliably since my thumb doesn't have to be committed to B as well.Note on Inputs #3: I realize my description of the inputs is mediocre at best. When I started learning it, I consciously thought of it in 2 steps. 1. Cancel Run into Needles (with whichever direction you want, essentially the start of a wave needle if your going to B-reverse) and then 2. as quickly as my fingers can (you should still be within the first few frames of bringing out needles), buffer the input of the attack I want to use, and like a frame later add in a brief L to add in this "go to neutral" weirdness phase.Originally I couldn't get it to work with grab (I could have just been failing) so the closest thing I could pull off was thisWave Needle standing grab:Edit: Actually there does seem to be a grab option with that seems better than a regular boosted grab. Will have to try to figure out the inputs more precisely. Ill post any gifs of it right here if/when I do.Edit2: This may actually be a roll cancelled grab.----------------------------------------------Tech 1.5: Landing Attacks out of aerial Needle Charging-----------------------------------You can actually still do these almost as fast using the tech below. it's still not quite as fast, but its faster than a normal B-Reverse while airborne.Inputs: While charging Needles in the air, buffer an attack just a couple frames before landing, then quickly press shield to cancel the charge and let the buffered attack come out.While airborne:(my) > About to hit ground >(shield just as you hit the ground)------------------------------------------------------------------------------------------------------------------------------------------------------------------One other "weird thing". Every once in a while I accidentally do an extreme wave needle backwards while still facing the same direction I was running. It puts you into neutral extremely quickly too. Imagine a wave needle that's twice as fast and far, and keeps you facing forwards instead of turning you. No idea how to replicate this yet but it has something to do with left/right C-stick in combination of left/right stick while Needle CancelingEdit: This has been fully discovered now too and has a huge myriad of applications! See below!^ ---------------------------------------------------------Tech 2: Wavebounce Cancels-----------------------------------------------------------This "weird thing" has been Figured out thanks to the video by @ TheReflexWonder towards the bottom of this page! Its a Grounded Wavebounce Cancel that acts similarly to a backwards wavedash believe it or not. It can also be used in the air for forward-facing-yet-retreating needles, needle fidgit options such as airdash back and then cancel into bouncing fish, or for needle landing (which you can then integrate tech 1.5 out of).--New - Aerial and Grounded "WaveFish":(You can "WaveFish" in the air, while landing, on the ground, etc. In fact, It works exceptionally well with bouncing fish especially. Here are some examples.)Landing WaveFishGrounded WaveFish:Aerial WaveFish:(Uses the Needle Fidgit tech to cancel the wavebounce into specials, most notably Bouncing Fish and Vanish)--Making a Read:Wavedash into Shield & Punish:Avoiding & Punish (You could decide to not bring out her shield for faster punishes too):Reverse Momentum Forward facing Needle Edgeguard:Punishing Rolls:Punishing Dash Attacks:Covering the Ledge while recovering high:Releasing Needles instead of Canceling:Mindgames? (can be done a bit faster than done here too):While holding, press(Mytoo make it much easier), and then cancel withEdit4: Fixed up the post... a lot. Also, read the entire thread to get a full understanding of how everything works, as a good amount of information was discovered from various users as to how and why both these techs work.I don't play competitively so I'm not quite sure what the implications of this are... but something tells me 20XX includes Sheik.
