Guile's Invisible Throw, which has gained many nicknames such as the "Phantom Throw", "Magic Throw", "Shadow Throw" or "Scorpion Spear", is a glitch found in early arcade versions of Street Fighter II. If done properly, this glitch allows Guile to throw the foe without even touching them, and in some cases is considered a "cheat".
Activation
To do the glitch, one must charge back then hit forward on the joystick along with the fierce and roundhouse buttons. This is a precise motion; the roundhouse must be done slightly before the fierce and should be hit slightly after moving the joystick forward.
