Street Fighter II: V: 1x24

Nightmare Reunion

Bison orders Ryu to focus his ki to do the Hadouken. Ryu keeps doing the Hadouken for quite a while, and Guile and Nash infiltrate the fortress to get inside and rescue Ken from Bison. Ken slowly but surely summons enough rage to use the Hadou-Shoryu to break the wall between him and Ryu. Ken, after breaking the wall, tries to convince Ryu to come with him, but Ryu doesn’t answer, and stands there glaring evilly at Ken. Ken notices something is wrong with Ryu, but doesn’t know what. The episode ends after that.
