Todd was both an F.B.I. field agent and a chemist. However during an experiment, a strange purple gas was released accidentally into his lab. Because Todd could not escape, he inhaled large amounts of the gas which he discovered had given him superpowers such as flight, telescopic vision, and disintegrating beams fired from his hands. Todd then donned a bulletproof costume to become TNT Todd of the F.B.I. When a villain tried electrocuting him with high voltage wires, it only made Todd more powerful.
