|All appearances||+ (forward jump only)|
DescriptionEditExecuted by pressing a quarter-circle backward motion and kick during a forward jump, Cammy/the user performs a diagonal down-forward one-legged driving kick with deadly force. There is negligible difference between Cannon Strikes using different kick buttons. Prior to the Street Fighter IV series, the move could only be used at the apex of a forward jump.
The EX Special version introduced in the Street Fighter IV games has Cammy use both legs for the kick, and can be executed during any kind of jump, not just a forward one. In some crossover appearances, Cammy will not dive fully all the way towards the ground, and the move may stop mid-way depending on her height.
This move is a solid crossup tool, and good choice for closing in through the air or to quickly punish a whiffed attack; the EX version can also confuse and catch foes by surprise. However, if performed too high, the move may hit too early before the user recovers, making it less effective and very easy to punish. This makes the move most effective when performed as close to the ground as possible (with proper spacing based on the starting height).
