Here are an amusing couple of images from the She-Ra season one episode "Of Shadows and Skulls". The first image is very much in-keeping with Filmation's style of animation. However, when Skeletor frees himself it becomes all-too apparent that the animator is having a field day drawing Skeletor. Not only do we get incredible definition rendering on Skeletor, making him look super-buff, but we also see his belly button! It also appears that Skeletor has chest muscles where most men do not! For some reason this just makes me chuckle every time...
