The King of the Kickboxers (also known as Karate Tiger V and No Retreat, No Surrender 4) is a 1990 martial arts film directed by Lucas Lowe and starring Loren Avedon as Jake Donahue and Billy Blanks as Khan.

1981, Bangkok, Thailand. Sean Donahue is in the kickboxing ring against the current Thai champion. In his corner is his little brother Jake, who is cheering Sean on. Sean is able to overpower his opponent and wins after a spin kick knocks the Thai fighter out. Sean is rewarded with the championship. En route to their hotel after the fight, Jake and Sean are ambushed by some armed men. Sean is able to fight them off until he is shot at by Khan, who warned Sean he was not to have won the fight. Sean admits that it wasn't his intention but the opponent wasn't much of a contender. Khan, angry with the decision, fights Sean and obliterates him in front of young Jake. Khan performs a triple kick combination starting with a double jump kick to the head, followed by a double jump kick to the chest and a jump spinning back kick, which kills Sean. Jake, saddened and angry, races towards Khan who beats Jake up and knocks him out.

It has been ten years and Jake is now a New York City detective who has gone undercover to bust a drug deal in an abandoned warehouse. Jake mocks the dealer and tells the dealer that he is a cop. The dealer laughs it off at first, until Jake reveals his badge and wire, which infuriates his fellow officers. The dealer and his two men attempt to begin fighting Jake, who resorts to a street fighting style to ultimate stop the dealer and his men. SWAT arrives and the team leader is unhappy with Jake for his actions. Back at the office, Jake is getting reamed out by Captain O'Day, who tells Jake the dealer may have a chance to call police brutality due to his actions. However, O'Day makes Jake a deal that could get him out of his potential bind. Interpol has contacted NYPD about an operation involving snuff film and wants Jake to take on the operation. When Jake learns the operation is in Thailand, Jake refuses to take the assignment. However, that night, while viewing one of the films, he learns the man who stars in the film is Khan, which triggers the flashback of his brother's death. When Jake gets a call from O'Day to let him off the hook, Jake tells him he's taking the assignment.

Upon his arrival in Thailand, Jake meets his contact Anderson, who tells him that the men behind the snuff films look around for fighters to star in their films. Therefore, Jake must find a way to get attention. While this is going on, an American fighter, Dan Handel, is the latest star of Khan's new film, in which he learns the hard way about what filming is like. When Dan is cut for real and then shot at, he is shocked to discover the body of a dead woman. Khan arrives and beats up Dan before impaling him on a hook, causing his death. Jake's first attempt at a Muay Thai school proves to be unsuccessful. However, his actions grab the attention of Thasi, a Thai-American Muay Thai fighter. That night, as a reward for his latest actions, Khan is given a chance to choose a woman to spend the night with and chooses Molly, an American who came to Thailand to start a modeling career only to find herself duped with nowhere else to go. When she tricks Khan into doing a tradition of washing up for him, she escapes. When Khan sends men after her, Jake comes to her rescue and the two form a bond.

Kahn has not been a contender in any CBUB matches.
