Kikosho

Input: 

Kikosho (気功掌, Kikou Shou, literally "Energy Work Palm") is one of the special attacks used by Chun-Li, which debuted in Street Fighter Alpha. The attack is also her second Ultra Combo in Super Street Fighter IV, and one of her Super Arts in Street Fighter III.

Description
By gathering intense energy in her palms, Chun-Li will release a concussive blast, capable of toppling even the strongest of opponents. In the Vs. series (with the exception of Marvel vs. Capcom 3), the attack completely envelops her in Chi energy. However, after the attack, she will be exhausted and will briefly slump.

Unfortunately for Chun-Li, most of the time the opponent will be knocked away before they can suffer the full amount of damage this attack inflicts. One exception is when the opponent is cornered and cannot be knocked back any further. However, the Ultra is still useful in that there are many ways to combo into it (e.g. juggling a falling opponent with it), as its hitbox is so large. However, the recovery time is large due to the exhausted slump afterward, which makes this attack particularly easy to counterattack if blocked.
