During the eighties there were many Masters of the Universe coloring books, all of which featured a variety of artwork, with varying degrees of quality. Some artists put in a great level of detail, other artists simply copied model sheets, and some artists were just plain questionable. There were a batch of illustrations by one particular unnamed artist that I have a great affection for, mainly because the style is close to the cartoon, but bold enough to be identifiable as the artist's own! These images also showcased some pretty impressive scenes that I personally wish could have been seen in the Filmation series. In this illustration we see that Mer-Man's attack appears to only last a few seconds, as Teela somehow defeats him. Looking at this image my guess is that she has used some kind of explosive. For some reason I love the detail and crazy wide-eyed expression on Mer-Man's face!
