Sonic Typhoon (ソニックタイフーン Sonikku Taifūn?) is one of Guile's Super Combos, exclusive to Street Fighter EX2 for the arcades.
Guile charges up energy, and then he releases a crescent-shaped Sonic Boom that hits six times. It could be considered his counterpart to the Shinku Hadoken, as both function similarly.
In Street Fighter EX2 Plus, this move was replaced by a more powerful variant, the Sonic Boom Typhoon, which appears as Guile's Meteor Combo.
