Jason Bard was fascinated with traps since his childhood and as he grew up, he became a trap expert. In his adulthood, Bard was able to create the most intricate of traps to capture all sorts of wild animals, but his hunting of exotic species cost him a good time in prison. After his release, he decided to turn to crime and using his ability to create traps, he started a successful crime spree across Gotham. Bard was also able to capture Batman, using his traps, but the vigilante broke free and created the ultimate trap to capture "The Trapper".
