Jack Binder trained in the martial arts since he was a teen. When he came of age, he began to compete in mixed martial arts tournaments. Later, when he came across a mugging, he fought off the attackers and saved a couple from harm. This made him feel good, so he adopted the guise of MMA (Mixed Martial Artist). He modeled his alternate self from the golden age hero Daredevil, right down to the boomerangs.
