Need Help Finding This Obscure 80s or 90s Underground Fight To The Death Movie

Can you recall some other details - was cast primarily just regular actors from Holywood, Asian actors, etc. Low budget or a high-end production? Was it contemporary to time released (e.g. made and set in 1980s). Was it in English or any other language? Was the violence graphic R-rated or PGish? Do you recall the make and model of any vehicles and - any specific real songs used on the soundtrack (or was it just instrumental)?

@cinefyl​ Thank you so much for the response! It was not really anything like a massive hit movie or show. I don't recall it having huge actors in it either, but there again I was young at the time when I saw it so i may be wrong. It came on at like 12am around midnight when I was kid on late night Australian TV around id say between 2000 to 2005. The music sounded to me instrumental with Asian and combat tones to it. It had a very dark atmosphere. Almost like Mortal Kombat but more believable. There were a lot of fight scenes and all the fight scenes ended with a death. No KOs or tapouts. All the fighters would kill each other and advance on to thr next fight in the tournament. I distinctly remember one part of the movie where a dead fighter was thrown down a drain or a like a hole when he was killed in the arena. The hole was then covered as the next fighter came into the arena or pit. The killed fighter was wearing almost like a gladiator type of attire with a helmet I think. It would have to be definitely a rated R movie most likely due to the violence and decapitation of some of the fighters. I do remember it being a 90s or 80s type of setting or movie to. I'm sure one of the champion of the tournament or main killer/villain was potentially an Asian man with long black hair, either out or in a ponytail. He would wear like this black coat or a black singlet. Was very built. There was also a hero in the film that was the main character and he was after to win the tournament and the main villain. Weapons I saw were anything to martial arts swords or even medieval axes. I'm sure the main villain also had a blade in hidden inside his black hair. I think he had a Fu Man Chu facial hair to. There would have been Asian and American actors in it. The only other thing I truly remember. Is the old guy in the grey or black suit, with greyish hair and a goatee. Getting head from a hooker in his limo as its driving down the street or road. Please let me know if I can give you anything more? I've been trying to find this film for many years since I was a teen. There's only one other person I know who I met on reddit who remembers it and he cannot even remember the name of it. It may have also been a snuff based type of film story base where the owner was hosting illegal fights.

@Tk1416​ Hey man. Thanks for the comment! I do not believe it's this film though. I don't think Firepower has a fighter with a blade in his braid or ponytail. There are about 15 plus of us now in the hunt for this film. We have made a new reddit post about it with new confirmed details. Can I link it to you and can you confirm if you recognise it or not?
