Bloodsport III (1996) on Netflix

A little while after winning the Kumite, Alex Cardo--now an art dealer--no longer wishes to fight in tournaments. After Alex rejects millionaire, Jacques Duvalier's (John Rhys-Davies) invitation to a new Kumite he in sponsoring, Duvalier has Alex's spiritual father, Sun, executed. Feeling empty inside and wanting revenge, Alex is directed by David Leung (Pat Morita) to Master Makato "the Judge," Sun's brother who Alex met in the previous Kumite. Makato helps Alex rebuild himself and teaches him things to build on what he learned from Sun. Alex finally decides to compete to avenge Sun's murder and honour his memory. All of Alex's wrath and fight abilities may not be enough to stop Duvalier's evil henchman: Beast--the biggest, strongest, and most powerful fighter the Kumite has ever seen.
