He practiced martial arts at the Fighting Dragons studio from a young age, becoming a high-ranking black belt. Cheng is the counterpart to Johnny Lawrence: he is the wealthy, popular bully, the best student at his dojo, and a leader who torments the protagonists. He is 1.66m (5'5") tall, 13 years old, with a highly toned, mesomorphic athletic build. His physique is defined by speed, extreme flexibility, and explosive strength.

Dre Parker, 1.42m tall, a 12-year-old from Detroit, Michigan. His journey represents the classic arc of self-improvement, cultural adaptation, and maturation through martial arts. Initial traits: Insecure and nostalgic, proud and stubborn, peaceful but impulsive. Evolution: Disciplined, resilient, brave, and loyal. Training in kung-fu transforms his mentality and character.

Abusive coach: Trains Cheng under a militarized regime. Director of the prestigious but aggressive 'Fighting Dragons' Kung-Fu studio in Beijing. Tactical sadism: Orders students to deliberately injure rivals like Dre. Cruel and authoritarian: Philosophy is 'No Mercy'. He believes Kung-Fu is a destructive weapon. 52 years old.

Dancer and violinist. Her close friendship with Dre triggers Cheng's jealousy. She is a talented Chinese girl who plays the violin. Kind and empathetic, she appreciates Dre's charisma. Disciplined and pressured by demanding parents. 1.60m tall, 12 years old.

Sherry is Dre Parker's hardworking, protective, single mother. The driving force behind the move: After being widowed, Sherry accepts a job transfer at an auto factory that forces her to move her life and her son's from Detroit, USA, to Beijing, China. The optimistic compass: While Dre hates the change and feels like an outsider, she tries to maintain a positive attitude, constantly reminding him that this trip is a "big adventure" for them both. Ally to Mr. Han: Initially, she is firmly against Dre entering the martial arts tournament. However, after speaking with Mr. Han and understanding it is the only way for the bullies to leave her son alone, she puts her full trust in the handyman and becomes a great friend. Personality: Warm and loving: She has a very close, loud, and playful relationship with Dre. She shows him her love constantly through hugs and kisses (which sometimes embarrasses the pre-teen). Strict and disciplined: She does not tolerate bad attitudes or messiness. The iconic jacket training dynamic is born precisely because Sherry is always scolding Dre for leaving his clothes on the apartment floor. Resilient: Despite the immense weight of raising her son alone in a foreign country whose language she doesn't speak, she never gives up or lets Dre see her break down. She is 40 years old and stands 1.63 meters (5 feet 4 inches) tall.

Speaks in short sentences and gets straight to the point, avoiding long speeches. Metaphors and irony: Teaches through analogies and rhetorical questions to force the student to think. When Dre complains about repetitions, Han responds with cold calm or firm commands like "Again!" or "Stay still." Uses affectionate nicknames: Affectionately calls Dre "Xiao Dre" (meaning "Little Dre" in Mandarin), subtly demonstrating his fatherly role. Runs his own academy in Beijing. Travels to train his grand-nephew, Li Fong, combining his knowledge with Daniel LaRusso's karate. Global Grandmaster and Mentor. Protector and Shifu (Master). Height: Mr. Han is played by Jackie Chan, who is 1.73 meters (5 feet 8 inches) tall. On screen, his imposing presence does not come from height, but from his perfect posture, agility, and absolute command of his body space. Philosophical and peaceful: He sees martial arts as a tool for defense and self-knowledge, never for aggression. His famous phrase defines him: "Kung-Fu lives in everything we do... in how we take off our jacket, in how we treat people." Humble and low-profile: He deliberately hides his mastery of Kung-Fu. He prefers to pass for a simple handyman rather than seek fame or show off his skills. Stern but compassionate: He is not a warm teacher at first; he demands absolute discipline and does not tolerate complaints, but acts driven by a genuine desire to protect the weak. Mr. Han is introverted, melancholic, and reserved, marked by severe post-traumatic stress disorder due to the death of his family. He is a character of deep emotional complexity, whose design balances the mysticism of classical martial arts with human pain. He is 53 years old.
