Publishing History: This series was published from 2002 to 2003 by Image - Devil's Due Publishing (DDP). It was the second ongoing G.I.Joe series published by Image/DDP. The series kicked off with Larry Hama writing the first 4 issues in a storyline called "The Mission that Never Was," which took place one month after Marvel's original A Real American Hero series ended. The first 4 issues also had back cover art, but none of the following issues did so, except for Issue 17. After that the creative team was a recolving cast from one story to the next. The rest of the stories fit into what was happening in Image/DDP's monthly main title.
