Bloodsport is a 1988 American martial arts action film directed by Newt Arnold. It stars Jean-Claude Van Damme, Donald Gibb, Leah Ayres, and Bolo Yeung. The film is partly based on unverified claims made by martial artist Frank Dux. It sold well at the box office, grossing $65 million on a budget of $1.5–2.3 million. Bloodsport was one of Van Damme's first starring films and showcased his athletic abilities. It has since become a cult film.

U.S. Army Captain Frank Dux (Jean-Claude Van Damme) has trained in the ways of ninjutsu under his sensei Senzo Tanaka (Roy Chiao). As a boy, Dux and a group of his friends broke into Tanaka's home to steal a katana, but Dux was apprehended while returning the katana to its place. Impressed by Dux's integrity and toughness, Senzo decided to train him alongside his son, Shingo (Sean Ward). After Shingo's death, Senzo trains Dux as a member of the Tanaka clan. Dux is invited to the Kumite, an illegal martial arts tournament in Hong Kong. After his Army superiors refuse to let him go, Dux goes absent without leave, says goodbye to his sensei and leaves for Hong Kong. Two Criminal Investigation Command officers, Helmer (Norman Burton) and Rawlins (Forest Whitaker), are assigned to track down and arrest Dux.

After arriving in Hong Kong, Dux befriends American fighter Ray Jackson (Donald Gibb) and their guide Victor Lin (Ken Siu). When they arrive at the Kumite arena, the officials are skeptical but eventually accept them after Dux proves his connection to the Tanaka clan by performing the "death touch." On the first day of the tournament, Dux earns the enmity of the ruthless Kumite champion Chong Li (Bolo Yeung) after breaking his record for the fastest knockout.

Dux becomes involved with American journalist Janice Kent (Leah Ayres), who is investigating the Kumite. Although Dux refuses to help her, she sneaks into the arena by agreeing to a date with another spectator. On the second day, Jackson is matched against Chong Li. Although Jackson comes close to defeating Li, he wastes time gloating, allowing Li to recover and viciously beat him. Dux visits Jackson in the hospital and vows to avenge him. After witnessing the brutality of the tournament, Kent argues with Dux and tries to convince him not to return. Dux tells her that he has to win in order to become the best he can be.

Frank Dux has not been a contender in any CBUB matches.
