Heavy Metal (animation)/Nightmare Fuel

• Heavy Metal was R-rated for many good reasons, including two segments filled with this brand of nightmare fuel: "B-17", which features not only most of the bomber plane's crew being killed in big bloody messes to the tune of a driving heavy metal song, but then it has a a zombie plague, and the part in the "Captain Sternn" segment where a trial-witness gets increasingly angry whenever the prosecutor asks him questions -- eventually turning into an Incredible Hulk-like thing.
