Firefly's given name is unknown. Even Cobra Commander doesn't know his real name or what he looks like. Firefly is a ninja master, a saboteur, and an expert in all NATO and Warsaw Pact explosives and detonators. He always places his charges in the proper location for maximum damage. His fees are paid into a numbered Swiss bank account, and are always paid in advance. He makes no guarantees, and gives no refunds.Firefly also tends to go together with Black Out and Munitia as H.I.S.S. (short for Hierarchy of Infiltration, Stealth, and Sabotage).
