Master Li is the main antagonist from the 2010 film remake of The Karate Kid. He is a Kung Fu teacher, who teaches his students to be merciless, and is the master/owner of the Fighting Dragons Kung Fu studio.
He was portrayed by Yu Rongguang.
Master Li is essentially the Chinese counterpart of John Kreese from the original Karate Kid trilogy. Master Li is the owner and shifu of the Fighting Dragons Kung Fu dojo, which similar to the Cobra Kai dojo in the original trilogy, teaches its students to break their opponent's bones and be merciless towards them at all costs. One day Dre Parker and his apartment's maintenance man, Mr. Han, interrupt a lesson due to an earlier incident when six students from his dojo who nearly killed Dre; to offer a peace offering. Li harshly rebuffs the offer and then he orders that either Han or Dre get on the matt and fight one of his students. Then Han sees a way to get Dre to defeat Li's students fairly, which is an open Kung Fu tournament. Master Li agrees, and begrudgingly agrees to a certain condition of Mr.Han's which is that Dre is to be left alone so that he can prepare for the tournament. He then orders his students to do so in Mandarin. Li then tells them both not be tardy for the tournament & should Dre be late, the bullying from his students and him will only get worse for both Dre & Mr.Han. The day of the big Kung Fu tournament, Master Li tells one of his students to break Dre's leg and said student succeeded in doing so but got disqualified in the process. Han then heals his leg in a way similar to how Mr. Miyagi healed Daniel Larusso's leg. Master Li congratulates Han for getting Dre back on the mat and watched as his top student Cheng fought against Dre. However, in the end; Cheng winds up getting defeated, presenting the trophy and apologizes to Dre for beating him up. & pretty soon, Cheng and the rest of the Fighting Dragons students end up bowing down to Mr.Han. Also, Master Li lost all his students to Han after losing to him in a fight. It is currently unknown what happened to Li afterwards, though it is quite possible that he was eventually sent to prison for what he was teaching his students.
- In a deleted scene, Master Li was super pissed off at Cheng for losing to Dre and showing respect towards both him and Mr.Han. Master Li is about to slap Cheng, but Mr.Han fights Li and nearly defeats him (mirroring the beginning of the 2nd movie). Li was seen resting angrily, and later got punched by Dre's mother as punishment for ordering his students to attack her son. It got removed apparently because it would have taken too much focus away from Dre's victory.
- In the biggest twist of irony, despite being the titular martial art; neither Li nor the other characters of the film are shown using karate to fight, using kung fu instead. Indeed, back when the remake was in development, Sony considered to change the title to reflect this, but the franchise producer Jerry Weintraub rejected the idea, possibly to keep the title in line with that of the previous films.
