Tenshin

The Tenshin is a special attack used by Fei Long in the Street Fighter games. A similar attack, Zenpou Tenshin, is a special attack used by the Lee brothers, Yun and Yang.

Description
Both versions are executed by performing a half-circle backward motion and pressing kick.

Tenshin
Fei Long uses his leg and hooks it with the opponent's, flipping over them to the other side. It is not a move that inflicts damage, but is rather meant for positioning, as the technique allows Fei Long to trick his opponent and set up different kinds of combos. Since it is a command grab, it cannot be blocked.

The EX version of this attack allows Fei Long to grab his opponent at a little more further distance than the normal version, and is also rather faster than the normal version. Another property of the EX version is that immediately after using it, whatever attack Fei Long follows up with cannot be blocked.

Zenpou Tenshin
Yun/Yang grabs his opponent by the shoulders and flip over them, landing on the far side. The "attack" does no damage and is used to disorient the opponent; immediately afterward, there is a split-second window for the Lee brother to follow up with an attack or combo. The technique is almost identical to Fei Long's version.
