As a child, Bart Hill was witness to his parents' brutal murder. The murderer also branded Bart with a hot iron, leaving a boomerang-shaped scar on the left side of his chest. This traumatic experience left the boy mute. He trained his entire life in the art of the boomerang, eventually becoming a master boomerang marksman. He then developed a costume and took to the streets as the vigilante crime-fighter Daredevil.
