Sonic Boom

Name: Sonic Boom

User: Guile, Charlie, Remy, Seth,

Debut: Street Fighter II

Sonic Boom is Guile and Charlie's trademark projectile. It involves two waves of energy released by a quick arm-cross slash. In Street Fighter III: 3rd Strike, he fires it like Charlie, one - handed. Seth fires his Sonic Boom, like Remy's, with the same command input as the Hadouken.

Trivia

 * Sonic Booms, if looked at closely, consist of red, white, and blue, the color of America's flag.
