The Scorpion Threatens Aunt May

ASM 146. The villains seem to find Spiderman's soft spots. Peter Parker doesn't know it, but the Jackal has discovered his identity. There are many issues where he tries to torment Parker by using this knowledge. He created the Gwen Stacy clone. Now he's sending the Scorpion after May. It takes many issues before Parker even knows what is going on. That part of the story was pretty good. Probably the best thing that Conway did, story wise. Also notable for full-page art.
