Guile and Chun-Li must not only face and fight the man they once knew as Charlie, but also the man responsible for their pain and suffering - M. Bison! Guile and Chun-Li appear to finally have the man they've been seeking right where they want him, but soon discover that Bison wields a weapon neither of them had anticipated the mysterious and destructive force known as "Psycho Power". Will they manage to overcome this power, or will Bison make them slaves to it?
Meanwhile, Akuma, the man - or perhaps monster - responsible for the death of Ryu and Ken's master, finally comes face to face with them. Much like Bison, Akuma is keenly interested in Ryu, but for what, remains a mystery. Does he hope to destroy Ryu as he did Gouken, or does he wish to perhaps offer Ryu a forbidden fruit that his master had always kept hidden from him.
