Cobra Kai‘s fourth season finale revealed how Terry Silver installed himself as the most dastardly karate villain of the franchise. He’d made sure that John Kreese got framed for his own (brutal) misdeeds and put behind bars for the time being. The Season 5 trailer revealed how Terry was making good on his threat to expand the Cobra Kai dojo throughout the Valley and make “no mercy” a standard for like a billion more schools.
