Cannon Spike

Input:

The Cannon Spike (キャノンスパイク, Kyanon Supaiku), also known as the "Thrust Kick" in SSFII, is a move performed by Cammy, Juni and Juli. It originated from Super Street Fighter II and returned in the subsequent Alpha series of games, as well as the Street Fighter IV series.

Description
The user launches in the air leg first for a singular, powerful strike that often over powers any aerial strike. Upon impact, they flip backward to a relatively safe distance, though some games increase the length of their recovery animation to increase chance of retaliation.

Trivia

 * In the 1994 Street Fighter movie, Cammy can be heard yelling "Thrust Kick!" while fighting soldiers near the end of the film, though she's doing a standard kick at the time.
