The Forbidden Zone was a 4-issue comic mini-series that ran from December 1992 to March 1993. The series was published by Adventure Comics, an imprint of Malibu Graphics, and was written by Lowell Cunningham. It appeared six months after Malibu's regular Planet of the Apes comic had ceased publication, and as such it represented the company's last association with the franchise, and also the last Apes comics until Dark Horse Comics launched a new line on the back of the 2001 re-imagining. The artwork of Leonard Kirk was amongst the best examples of Planet of the Apes comic-book art, with - unusually - accurate representations of the ape species in terms of comparative size and shape and facial features.
