Dural (デュラル, Dyuraru?) is an android-like creature that debuted in the original Virtua Fighter. Dural is the game's boss character. According to canon, the first model was Kage-Maru's kidnapped mother. She fights with a mix of all the other characters' styles. Dural is a secret character in the series. Her name is a direct reference to the joypad manipulation needed to have her as a playable character (at least in most home version): Down, Up, Right, then A button plus Left together (D,U,R,A+L).
Dural was previously a human woman. Her name was Tsukikage and she was both Kage-Maru's mother and a Kunoichi. When the mysterious corporation J6 (Judgement 6) noticed her exemplary fighting ability and resilient body, they captured her and used her as their prototype for their terrifying Dural project. Arming her body with various cybernetic enhancements and brainwashing, she became a cyborg, immune to feeling.
