Hey guys, Ryan here. I wanted to put this up because it seems like a lot of people don't understand how Lightning Legs work. Well the partitioning part anyway.
Why learn this?
Lightning Legs are great because they are very safe and will beat single option parry's. Not to mention that you get great meter on hit or block!
Myth : Just press the button 4 times and then you can wait to press the fifth one and Lightning Legs will come out.
Truth: Well this is only partially true. You see, LL has its own separate gauge that you cannot see (regular charge moves have this invisible gauge too!). Constantly throughout the match, the gauge is going from full to max from to full max full to max and so on. Once your gauge gets empty, you CANNOT partition legs anymore. Here's a video showing the gauge, it's the pink one:
How can you know when the gauge is full or empty?? Luckily, there are a few different ways the gauge will reset itself to 100% full. They are:
•During super freeze
•If you press a kick button 5 times
•When you do Lightning Legs
•When you parry something
•When the round ends
So how do you do specific walking Lightning Legs setups?
The easiest and first one you should learn is post Houyoku-Sen jumping HP. HP-->walking Lightning Legs. High jump cancel after the super and do jump HP HP. When you're falling back to the ground you tap kick (I believe RH to be the best Lightning legs so I always use RH) 4 times. It has to be 4 times. Not 3 not 5. When you land the invisible gauge is at the perfect full length to walk for a substantial amount of time. Try it! Walk forward and then press RH once. You will get Lightning Legs! Press two buttons for the 5th button and you'll get EX!
This next setup is much harder, but also much better because it's almost completely ambiguous.
Post Houyoku-Sen jump LK into Lightning Legs. It is your choice what side you land on! (You do need to learn the specific timings for each character in order to cross up. Example: Some characters you need to delay the initial jump Lk.)
If you try this setup, you will be met with great frustration. The walking Lightning Legs won't come out! The reason why is because after your Houyoku-Sen, the Lightning Legs partition gauge is not synched up to allow any leeway with walking and activating the move.
The secret: During the second set of kicks during Houyoku-Sen, you need to press RH 5 times. The fifth press should coincide with the last hit of Houyoku-Sen. This resets the gauge. Jump LK and press RH another 4 times. Upon landing you now have time to walk under or not and do Lightning Legs. Nuki has mastered this technique and it almost guarantees some kind of damage post Houyoku-Sen.
So remember you have to press RH a total of 9 times in order to store it post jump LK. It is very important to be precise. Press the button 8 or 10 times and it won't work.
Houyoku-Sen -> press RH 5 TIMES during the second set of kicks (doesn't have to be fast, try it out) jump LK and press RH 4 more times and now you can do walking Lightning Legs.
Hope this helps....Good luck guys!
