Karate Kid
(2010)

Master Li instructs his student in the semi-finals to go "no mercy" on Dre. He pummels Dre's knee, incapacitating him and getting himself disqualified. Though Mr. Han tries to talk Dre out of fighting the final match, Dre gets him to perform the "fire healing" on his knee so that he can fight the last fight. In a sudden death moment, Dre decides to use the Cobra technique he witnessed at the temple. By mimicking his opponent's movements, Dre manages a flip kick to get the final point to win the tournament.

Afterwards, all of Master Li's students line up and bow to Dre and Mr. Han.
