The Hurricane Kick (竜巻旋風脚, Tatsumaki Senpuukyaku, lit. "Tornado Whirlwind Leg") is a special move that is usable by Ryu, Ken and many others who follow a similar martial art of its origin. Ryu's version stands out most games being a single hit version that knocks down on either blow. However, in some Vs. Capcom games, Ryu is able to have his knockdown and do multiple hits in a similar manner to the Tatsumaki Zankuukyaku, it can only best apply in the corner. Ryu's version tends to be easier to punish if the more eariler hits tend to knock down the opponent before Ryu recovers.
Another way to use a Tatsumaki is often to work it in midair, for its axis varies during what kind of jump Ryu does in midair (if neutral, he moves forward a bit; if moving backward or forward, the attack will carry on in that direction). Since the attack spins all around Ryu, it's possible to use it as a jump-in type crossup.
Shinkuu Tatsumaki SenpuukyakuEdit
Shinkuu Tatsumaki Senpuukyaku (真空竜巻旋風脚, lit. Vacuum Tornado Whirlwind Leg), this move is a powered up version of one of Ryu's Tatsumaki Senpuukyaku, just like Shinkuu Hadouken. He winds up, hops into the air and performs many rotating kicks, remaining stationary (unlike this move's special counterpart) and gaining a slight vacuum effect. Unlike other moves with a similar vacuum effect, the range of it is an invisible force that can pull in an opponent at a certain distance into the whirling maelstrom of kicks. Sometimes appears as an EX version of Ryu's normal Tatsumaki Senpuukyaku in SFIII and IV.
In Ultimate, the Tatsumaki Senpuukyaku has a variation known as the (真・竜巻旋風脚, lit. True Tornado Whirlwind Leg) that is available during the Hadou Kakusei's duration. This version sports storm effects such as lightning storms and a large grey tornado, applifying the technique's effect.
