Taking these events as an omen, Lynns designed a colorful costume based upon the insect and called himself the Firefly, making good use of his knowledge of lighting effects. However, his career was brought to an abrupt end when he was eventually captured by Batman and Robin. Lynns went on to battle Creeper and the Outsiders under the guise of Firefly.
