Though his true identity and birthplace are unknown, the mercenary called ZARTAN is one of the G.I.JOE Team's most dangerous and devious foes. That's because ZARTAN could be anyone, anywhere at any time. He is fluent in more than twenty languages and dialects, a ventriloquist, and capable of imitating the voice and physical appearance of virtually anyone he wishes. It's a set of talents that the terrorist organization COBRA finds particularly appealing. The group frequently employs ZARTAN to use these skills to deceive the Joe team and gain access to information that COBRA can use against anyone who dares oppose them.
Yet ZARTAN would not have benefitted from multiple lucrative assignments from COBRA COMMANDER himself had the master of disguise not proven himself in battle. He is a master of martial arts and archery, and he commands a savage group of other mercenaries known as the DREADNOKS. Despite them all having a collective foe in G.I.JOE, ZARTAN only looks out for himself in the end. He is always seeking new personalities to imitate, new bank accounts to empty, and new methods for disposing of those who cross him. As he delves further into the lives of others, though, ZARTAN might be in danger of losing himself in the process.
