He is portrayed by William Christopher Ford.
Dennis, like Snake, could be another son of Terry Silver, but it is possible that he is just a martial arts acquaintance. Dennis oversaw Mike's training for the upcoming tournament. Dennis is not as skilled as Mike nor Daniel, due to the fact that Daniel had easily defeated him during a second confrontation on Miyagi's bonsai shop and a sparring match against Mike on the Cobra Kai dojo, in which he lost.
- Dennis rarely speaks. He only has two lines throughout the entire movie.
