Bloody Roar (ブラッディロア, Buraddi Roa^?) is a series of fighting games created by Hudson Soft, and developed together with Eighting. The series has been published by multiple companies, including, Virgin Interactive, Activision and Konami.

Hudson Soft later became a subsidiary of Konami.

The series began in 1997 under the name Beastorizer. The game's theme incorporated anthropomorphism, where the player has the ability to transform into a half-human, half-animal creature known as a Zoanthrope (The name came from the clinical term, 'zoanthropy', which is similar to that of lycanthropy, but not just with the mind-set of a wolf). The game would appear under the name "Bloody Roar" when ported to the PlayStation in 1998, which would become the permanent title thereafter. There are three Bloody Roar sequels, plus a game based on a sidestory set between 3 and 4 on the Nintendo GameCube which was later ported to the Xbox.

The following is a complete list of the games in the series:

Bloody Roar has kept somewhat the same controls over the series. A button each for both punch and kick, the beast (transform/attack) button and a fourth button that has been either a throw button, a block button, an evade button (Introduced for some characters in Bloody Roar 4) and a rave button (An early version of the hyper beast in Bloody Roar 1 only)
