Terry Silver
Possible spoilers for those who have not seen The Karate Kid 3.
For those who have not seen the movie, watch it. Great 80s style movie. Terry Silver was one of the coolest over the top bad guys of any franchise. Thomas Ian Griffith did a great job of acting Terry Silver, the rich evil guy. That would be so cool if he returns to Cobra Kai. Thomas Ian Griffith is actually younger than Ralph Macchio in real life.
