The Tatsumaki Zankukyaku (竜巻斬空波脚, Tatsumaki Zankuukyaku, "Tornado Air Slashing Leg"), also known as the Hurricane Scythe Kick, is a version of the Tatsumaki in the Street Fighter series. It is ultilized by Akuma and Evil Ryu.
Like quite a few of Akuma's attacks, this attack has the properties of Ryu and Ken's Tatsumaki. It hits multiple times like Ken's version, but is as strong as Ryu's version and faster, albeit harder to control. The EX version has Akuma spin in place, also similar to Ryu's.
In some games, the attack takes on lightning-elemental properties.
