It’s absolutely surreal to look at the first issue where Spider-Man fights Carnage, “The Amazing Spider-Man #361” (1992). If you were to replace that super-powered symbiote with a gun, Carnage is hardly different than mass shooters and other serial killers.
Carnage stalks and taunts a victim. He appears as a slender man covered in a red-and-black blood-like goo suit with lidless white eyespots. The text in the comic says “But you don’t get it all, do you? This ain’t a movie chip-man! Ya can’t run off the set!”
