Pre Karate Kid
Exactly when the LVKC was founded is never known as it is a minor dojo in the Karate Kid Series. In the 1981 All Valley tournament, Darryl Vidal, their top and only named student, won the title. It is unknown if the dojo competed in 1982. In 1983, Daryl lost in the quarterfinals/semifinals to Tommy of Cobra Kai and the third place match to Bobby Brown of Cobra Kai. It is unknown if there was another student to make it further than Vidal.
The Karate Kid
Various other students are seen along with Vidal who returned to the tournament in 1984. The furthest to make it is Vidal, who loses to Johnny Lawrence in the semi finals. Despite not making the finals, the students cheer on Daniel when he uses the crane kick to defeat Johnny and win the tournament for the first time.
The Karate Kid Part II
The dojo's students can be seen in the background during the opening recap of the first film.
The Karate Kid Part III
The LVKC returned to compete in the 1985 All Valley Tournament. It can be assumed that Vidal did not return due to turning 18. The only named member is a student named Orshan who lost in the semi finals to Mike Barnes. Their fight, however, was never shown on screen and only seen through the name cards in the back of the arena. Although they don't make the finals, they do cheer on Daniel when he uses the kata to defeat Mike Barnes and win the tournament the second time.
Post Karate Kid Part III
It is unknown if Locust Valley disbanded sometime after the 1985 tournament as they have not appeared in the webseries Cobra Kai. However, in the third season of Cobra Kai, an article about the 1983 All Valley stated that Vidal was upset by Tommy in the semifinals and beaten by Bobby in the third place match.
