Thomas "Tommy" Arashikage - A ninja trained in martial arts who serves as both an assassin and bodyguard for Cobra. His origin varies depending on the source – in various cartoons, he is a cold-blooded villain and unrepentant killer. In Marvel Comics (which reveals that he served in the US military in Vietnam with Snake Eyes and Stalker), he joined Cobra in order to gather evidence and clear his name after having been framed for the murder of the Hard Master by Cobra operative Zartan. Storm Shadow eventually leaves Cobra and becomes a member of G.I. Joe, though captured and brainwashed by Cobra Commander to once again serve Cobra. He then breaks free and rejoins G.I. Joe. In the Sunbow/Marvel cartoon, Storm Shadow was depicted as a rival to Spirit and later Quick Kick instead of Snake Eyes. In the DIC cartoon, Storm Shadow only joined Cobra to find out who dishonored his clan before defecting to G.I. Joe. Zartan - The leader of the Dreadnoks, a master spy and assassin. He is a master of disguise, often literally morphing into the exact physical form of the person he seeks to impersonate (an ability attributed to a series of mysterious genetic experiments he endured). In most storylines, Zartan is also capable of changing his skin color to blend in with his background. His special ability is disrupted by sunlight. Minor command Major Bludd - Major Sebastian Bludd is an Australian mercenary with extensive combat experience, who sometimes works for Cobra. He is a master tactician and is an expert in all known weapons. Usually portrayed as Cobra's infantry commander, Major Bludd is best known for the assassination of General Flagg, the original leader of the G.I. Joe team, as well as for the running gag that Bludd wrote very bad poetry. Firefly - The world's greatest saboteur, Firefly's background is a mystery. A mercenary and assassin, Firefly offers no guarantees or refunds. He is portrayed as an expert in all types of explosive ordnance and demolition materials. He is also the faceless master of the Koga ninja clan. Doctor Venom - A Cobra scientist who played an important role in the first two years of the comic book story. He was then portrayed as having been killed in action, eventually to be replaced by Doctor Mindbender. Scrap-Iron - The anti-armor specialist of Cobra. Along with Dr. Mindbender, he also invented
