Terry Silver

Terrance "Terry" Silver is a fictional character and one of the main antagonists of The Karate Kid media franchise, portrayed by actor and martial artist Thomas Ian Griffith. He was created by American screenwriter Robert Mark Kamen and introduced in the 1989 film The Karate Kid Part III. Thirty-two years later, Griffith reprised the role in the sequel television series Cobra Kai, appearing as a main cast member from its fourth season to the sixth and final season.

Silver is the former best friend-turned-arch-enemy and fellow Vietnam veteran of Cobra Kai sensei John Kreese, and the co-founder of the dojo itself, as well as the arch-nemesis of Daniel LaRusso and later on Johnny Lawrence.

In The Karate Kid Part III, he is depicted as a megalomaniacal and sociopathic businessman who mentally tortures Daniel in an effort to get revenge on him for getting Kreese's dojo shut down. In Cobra Kai, he is shown to have reformed, only for Kreese's return to cause him to mentally devolve into his old state and later usurp him as the main sensei of the dojo, making him the biggest threat in the series.

Franchise creator Robert Mark Kamen initially refused to return for the third The Karate Kid film, as he wanted to take the franchise in a new direction. Inspired by Hong Kong Kung Fu films, he wanted to write a prequel story that would take Daniel LaRusso and Mr. Miyagi back to 16th century China. Both the president of Columbia Pictures Guy McElwaine and producer Jerry Weintraub refused this idea. When Dawn Steel took over from McElwaine, she offered Kamen a deal to write a third film and convinced him by saying that someone else could mess up the characters.

John Kreese was initially intended to have a larger role in The Karate Kid Part III. Due to Martin Kove’s schedule conflicts with Hard Time on Planet Earth, the character of Terry Silver (Thomas Ian Griffith) was written into the script, replacing Kreese's role. The Karate Kid Part III was Griffith's first film role. In his youth, Griffith had studied acting and also trained in kenpo karate and tae kwon do. Prior to his casting, he had performed on and off Broadway. Griffith stated that when he was cast in the role, Silver was not written to do martial arts but to antagonize Daniel LaRusso. The narrative shifted after fight choreographer Pat Johnson learned of his background in martial arts. Griffith considered the role of Silver to be out of his reach because he was aged 26 at the time and the character was a Vietnam War veteran about two decades his senior. Ralph Macchio, who was aged 27, performed the role of LaRusso, a teenager. Griffith presumed he would be instead cast as Mike Barnes, a karate champion who fights La Russo.

Director John G. Avildsen became interested in developing Terry Silver as a martial artist after discussing it with Griffith and agreed to add some fight scenes into the role. He gave Griffith opportunities to input ideas into his character. Griffith said the role was portrayed to be larger than life, "to give the adults a laugh and be all scary for the kids". Griffith came up with ideas for antagonizing LaRusso and Avildsen attempted to incorporate them into the film. Griffith portrayed Silver as a psychotic man who enjoys torturing teenagers but he was worried by Silver's personality, considering his portrayal to be too excessive. Avildsen instead encouraged him to use his instincts and play a more over the top character.

In developing the character for Cobra Kai, series creators Josh Heald, Jon Hurwitz, and Hayden Schlossberg thought of Silver as a "really scary Bond villain". They took aspects of the character from the film and wrote him into a modern story. In the series, Silver is enjoying his wealthy lifestyle and shows little interest in getting involved in Cobra Kai with Kreese. He tells Kreese that in the 1980s he was addicted to cocaine and thinks it insane that he was fixated on torturing a teenager. Heald explained that they added the cocaine to his character's backstory to explain Silver's maniacal behaviour and said he had a "Charlie Sheen kind of Wall Street-like lifestyle". The creators insisted that Griffith keep his hair long so that he could wear the character's signature ponytail in the same style as his appearance in The Karate Kid Part III. Despite being uncertain about returning to the character, Griffith was swayed by the detailed backstory that the creators had devised for Silver, which explained much of the character's personality. Griffith described Silver as a "super-smart guy" who attempts to distract himself from his inner demons by his wealthy lifestyle but Kreese brings his demons back and it consumes him.

The Cobra Kai creators were keen to reinvent Silver as a more three-dimensional character rather than the archetypal villain of the 1980s. Griffith said that he was not interested in repeating the same performance, but wanted to stay true to the essence of the character. His fighting style was designed to express the character of Silver in the way that he moves, which Griffith likened to a "coiled snake". He said that much of Silver's character is affected by his time in Vietnam, explaining that he clearly suffers from addiction and post-traumatic stress disorder. He described Silver's journey as a "path of survival" but thought that he is unable to change his path for the better having lived it all his life. In the series, Silver shows moments of vulnerability by asking Daniel for forgiveness. Griffith said this is based in Silver's need of "wanting to be loved, wanting a friend, wanting forgiveness".
