— Chan Kang
In the film, after his older brother left the Shaolin Monks and went to America, Chan took his place and began training for the tenth Mortal Kombat tournament. One night, Shang Tsung visited the Monks' Temple and confronted Chan. The two fought, but Chan was easily defeated by the sorcerer. Shang Tsung killed Chan and took his soul, leaving a cryptic message for Liu as a warning. Chan's dead body was found the next morning by his grandfather and fellow Monks.
Liu Kang enters the tournament to avenge his death. Throughout the movie, Liu Kang harbors feelings of guilt for not being able to protect his brother. During the final battle between Liu Kang and Shang Tsung, the latter attempts to lure Liu Kang to his death by morphing into his brother. While initially shocked by the image of Chan, Liu doesn't fall for the trick, however, and defeats Shang Tsung which results in the release of all the souls that had been taken by Shang Tsung, including Chan's, who greets his brother. Before ascending to the afterlife, he tells Liu that his spirit will always be with him until they are reunited.
- In actual Mortal Kombat canon, Liu Kang does have a younger brother. However, he is named Chow in Liu Kang's MKI bio. It is unknown whether Chow is alive or deceased.
- In actual Mortal Kombat canon, Liu Kang's surname is "Liu". However in the film, the siblings' surname is "Kang" possibly because the crew treated "Liu Kang" in Western naming convention.
