Executed by moving down-forward and pressing heavy kick, Chun-Li jumps and flips to her opposite side and hits her opponent with a backward-facing landing stomp. Shadow Lady also performs this move the same way and with the same command in Marvel vs. Capcom: Clash of Super Heroes.
In Street Fighter IV and Street Fighter V however, Chun-Li instead literally performs a flying kick motion towards her prior position, almost akin to a one-legged kick version of her Tenshin Shuukyaku from Street Fighter III: 3rd Strike.
This move is often considered to be a staple flying-overhead command normal, though it can also be used as a cross-up if positioned right due to the angling of Chun-Li's leg. If this attack whiffs however, she can be punished. However, the actual utility of this attack often varies from game to game.
In IV and V, the attack is now solely meant for cross-up as it no longer has a hitbox in front of where Chun-Li lands due to its new animation, which limits but at the same time expands on its uses.
