S1·E29 Fight to the Finish: Final Round

Ryu, Ken and Bison are sent to a mysterious dimension, which seems to be the origin of both Bison's psychic powers and Hadou. Here Bison asks the two boys to join Shadowlaw, which of course refuse. A battle between the three ensues, where Bison seems to continue having the upper hand. Meanwhile, Guile keeps fighting against Chun Li, unable to overpower the girl until the chip falls off her forehead. Ken manages to weaken Bison with his Hadou-Shoryuken, allowing Ryu to finish him off with a combination of Hadou moves. With Bison finally defeated, Ken decides to go back home in America, while Ryu decides to sail away and keep explore his true self.
