Bloodsport or blood sport is any sport or entertainment that involves violence against animals.

Bloodsport includes coursing, combat sports such as cockfighting and dog fighting, or other activities. These usually involve blood being drawn, and often result in the death of one or more animals.

According to Tanner Carson, the earliest use of the term is in reference to mounted hunting, where the quarry would be actively chased, as in fox hunting or hare coursing. Before firearms a hunter using arrows or a spear might also wound an animal, which would then be chased and perhaps killed at close range, as in medieval boar hunting. The term was popularised by author Henry S. Salt (1851–1939).

Later, the term seems to have been applied to various kinds of baiting and forced combat: bull-baiting, bear-baiting, cockfighting and later developments such as dog fighting and rat-baiting. The animals were specially bred, confined and forced to fight. In the Victorian era, social reformers began a vocal opposition to such activities, claiming grounds of ethics, morality and animal welfare.

Frank W. Dux (pronounced "dukes") is an American martial artist and fight choreographer. Dux established his own school of Ninjutsu in 1975, called "Dux Ryu Ninjutsu". He was the inspiration for the 1988 film Bloodsport starring Jean-Claude Van Damme.

Dux states that he was introduced to and trained in Koga Yamabushi Ninjitsu by Senzo Tanaka. Dux's martial art style, Dux Ryu Ninjitsu, is not a koryu (15th century feudal form of Ninjutsu), but is still claimed to be "based on its Koga Ninja root principles of adaptability and consistent change." Frank Dux formulated the proprietary augmentation technology he calls DUX FASST (Focus-Action-Skill-Strategy-Tactics).

The accuracy of many of Dux's personal claims have been disputed, including his martial arts background, fighting in the Kumite, and prior military service. According to the Los Angeles Times, the organization that staged the Kumite had the same address as Dux's house, and the trophy he won had been bought and paid for by Frank Dux at a local trophy store. This was disputed by Dux stating that the receipt was fabricated.

Stan Bush is an American singer-songwriter and musician whose most notable work includes the songs "Dare" and "The Touch" from the soundtrack to the 1986 animated film The Transformers: The Movie, and "She's Got the Power", featured in the American voice dub of the animated series Sailor Moon. Other notable works include the songs "Never Surrender," "Streets of Siam," and "Fight for Love" from the movie Kickboxer, and "Fight to Survive" and "On My Own - Alone", the theme from Bloodsport. In 1987, Bush (and back-up band Barrage) wrote and recorded the ballad "Love Don't Lie", which became a minor MTV hit when covered a year later by House Of Lords.

Bush submitted two tracks for the producers of the 2007 live action Transformers movie, but they were not included on the final soundtrack. However, on July 3, 2007, Bush re-released his album In This Life with the two additional tracks he submitted for the Transformers soundtrack, which include an updated version of "The Touch", and an updated version of his song from BotCon 1997, "Ground Zero", retitled "'Till All Are One". Bush also recorded another, markedly different version of "The Touch" which was at first rumoured for possible inclusion in the 2009 sequel Revenge of the Fallen. The 2007 version of "The Touch" was later released as a free downloadable track for the video game Guitar Hero World Tour. More recently, Bush's aforementioned "Till All Are One" was used as the end credits song for 2010 video game Transformers: War for Cybertron.

Along with No Malice, his brother and fellow member of Clipse, he released the album Hell Hath No Fury, which was praised by critics, many of whom consider it to be a cornerstone in Hip-Hop and one of the best rap albums ever made.
