About Stored Specials:
Ive seen people saying Vega has no Stored Special.
The true is that he has no Stored Super (Wall Dive).
But he has the Flick Stored, you can confirm by reading NKIs wiki, but Ill cover it up here shortly:
Charge DB. Done!
Since you has charged, just dont press the direction FORWARD. You can Jump back, press s.back+Roundhouse, s.back+mk.
To release, just press Toward+Kick.
You can see ARG (the japanese Vega Player) using this a lot of times, like, corner the opponent, jump in HP, c.mk, c.mp (now it is charged), s.back+mk or s.back+mp/HP. Sometimes the opponent have a impulse to jump in when he sees Vega Standing. Good for you, just press F+Kick, and you will get a free 3 Hits Juggle combo.
Vega Wall Dive Super:
I dont remember who said this special is not good. It is definitely not good, it is awesome! Just do the super when the opponent feel safe do use a hadouken, or when you see the animation, I will cover up Chun-li to show how great it is. Do it, and once you are in the back wall (if you can cross-up the wall dive against Honda, for example, good, do it), you can press the button EARLY to grab Chun-lis jumping back, if you press very soon, you will hit her with the claw, she will fall, giving time for you to charge and try again, or mix-up. If you press timed right, you will grab her (this time is very short, but I dont know exactly how much), in this way, you can also grab shoryukens, not deep Shoryukens, cause when Shots are invincible, they are not “Grabable” (WTF?!), so is Boxers Headbutt anti-air. But grab them in the tip of the glove, at the maximum ou medium DP height. It will work.
The use of the Early button press works (and it will answer one of the page 2 first post questions about runaway) like when you are running away when cornered. Jump in back wall to wall dive, press punch as soon as you can, while holding forward to flee. It will hit standing characters in mid/close range screen, jumping in, falling from a jump in (when they try to lure you or just get close, and this is a perfect time to land a Super!), etc, the worst situation is being hit by a reverse DP when they are close to you, but you are free, anyway, from the corner.
It is fast, you can runaway almost safe.
Dont work against psychic DPs.
And about New or Old Claw, as I said the Super is Awesome, New claw for sure. The super takes Half life bar. The other half you already took!
