G.I. Joe: Operation Hiss

In 2010, IDW kicked off G.I. Joe: Operation Hiss, a single-issue comic that served as a prelude to the publisher's ambitious G.I. Joe: Cobra Civil War event. Written by Brian Reed with art by Agustin Padilla, this one-shot focused on the high-stakes infiltration of a secret Cobra facility, setting the stage for the larger conflict between Cobra Commander and Serpentor. Though brief, it's a key piece of IDW's modern G.I. Joe continuity, offering a tight, action-driven glimpse into the escalating internal strife of the terrorist organization.
