Zartan

Zartan is a master of disguise and mercenary operative who works alongside Cobra's inner circle — including Cobra Commander, Destro, and the Baroness — making him one of G.I. Joe's most dangerous and unpredictable adversaries.

Zartan slithers into the Modern Age IDW era with a debut in the legendary G.I. Joe: A Real American Hero #155 1/2 (2010), brought to life by the definitive Joe scribe Larry Hama alongside artist Agustín Padilla. This shadowy figure keeps genuinely dangerous company — Cobra Commander, Destro, Baroness, and Major Bludd among them — which tells you everything about the villainous world he inhabits across G.I. Joe: Origins, A Real American Hero, and Special Missions. With only six catalog appearances, this is a character for the dedicated IDW completist, a collector's quarry rather than a household name — and that relative scarcity only adds to the intrigue.
