Tatsumaki

The Tatsumaki (竜巻, Tatsumaki, "Hurricane") is a special attack with various names, being the most common on the Tatsumaki Senpukyaku, used by both Ryu and Ken, originated in the classic Capcom fighting video game series Street Fighter. The practitioner jumps and, while in the air, rotates his or her legs, kicking the opponent 1~3 times depending on button pressed. It is usually performed by moving the joystick or D-pad a quarter circle backwards the opponent from the down position, then pressing a kick button. Tatsumakis, in some games, have a few frames of invincibility, allowing you to pass through some fireballs, like Hadokens or Sonic Booms

Different Types of Tatsumaki
Tatsumaki Senpukyaku (竜巻旋風脚, Hurricane Kick, literally "Tornado Whirlwind Kick") – The normal version of Tatsumakis. It's user will jump in the air rotating it's legs, the duration of the rotation (together with the number of spins) varies accordingly to the button pressed. Can be executed while Airborne.

Shinkuu Tatsumaki Senpukyaku (真空竜巻旋風脚, shinkū tatsumaki senpukyakyu, "Vacuum Hurricane Kick") – A Super charge of the normal Tatsumaki Senpukyaku; when executed, the Shinkuu Tatsumaki Senpukyaku can hit the opponent multiple times, but, unlike the normal Tatsumaki Senpukyaku, it'll not move across the Screen. In Street Fighter IV, a weak version of it is executed as a EX Tatsumaki Senpukyaku, since Ryu won't move across the screen like the Shinkuu Version.

Tatsumaki Zankukyaku (竜巻斬空波脚, Hurricane Scythe Kick, literally "Tornado Whirlwind Air Slashing Kick") - A more powerful version of the usual Tatsumaki Senpukyaku used by Akuma.
