Satoru Tojo (東條 悟, Tōjō Satoru) is Kamen Rider Tiger (仮面ライダータイガ, Kamen Raidā Taiga, Masked Rider Tiger), one of the participants of the Rider Fight. As he was one of those who worked towards the goal of closing the Mirror World, his misguided morals of becoming a "hero" eventually led him down a twisted path, making him a unique wildcard amongst the Kamen Riders.
