Cobra HISS Mark-0 (GI Joe)

Cobra HISS Mark-0 (Prototype). This model is a composite of the original design concepts that eventually became the Cobra H.I.S.S. tank. Interestingly, the vehicles shown in the early issues of the comic book shared some of these design features (the dual cockpit, for example), so presumably they were penciled at the same time the toy was being finalized. As the story goes, Destro built only one of these then settled on a less expensive design. In real life, this shape was eventually recycled
