Having lost his friend Charlie, Guile continues to investigate Bison's crime syndicate Shadaloo along with Interpol agent Chun-Li. Although Guile is a chiseled, stoic fighter, he has a wife and daughter back home that play a very important role in his life, which gives Guile a compassionate side.
In Street Fighter IV, Guile's classic Sonic Boom and Flash Kick return, along with several equally old moves and a few new tricks as well. As has always been the case, Guile's Special Moves are charge based and require some forethought to execute.
