These are no ordinary keychains. Available for 7 different characters (Ryu, Ken, Chun-Li, Dhalsim, Akuma, Sagat, Guile), the Street Fighter Action Keychains re-create the standard punch and kick sounds from Street Fighter IV as well as each character’s special attacks based on joystick and button presses. So, say you decide to pick up the Ryu keychain, if you perform the half circle forward + punch, the key chain will sound off: Hadouken. Awesome.
