About this Issue

Amazing Spider-Man #138 is the debut issue of Mindworm (William Turner), a mutant psychic antagonist whose tragedy-driven origin gave Conway's late Bronze Age run one of its most distinctively empathetic villains — a character designed to be pitied as much as fought. The issue also marks a consequential domestic shift for Peter Parker: forced out of his Harry Osborn apartment after the destruction caused by the Harry-as-Green-Goblin storyline, Peter temporarily moves in with Flash Thompson in Far Rockaway, Queens, a transitional beat that bridged the end of one major story arc and the opening moves toward the clone saga. Positioned between the resolution of Harry Osborn's Green Goblin tenure and the earliest rumblings of the Jackal storyline, the issue functions as a narrative interlude that nonetheless introduces a character whose arc — from villain to tragic reformee to homeless victim — would be revisited across three decades of Spider-Man continuity.

In "Madness Means... the Mindworm!", Peter Parker struggles to cope after his apartment is destroyed in a clash with the Green Goblin, turning his usual struggles into a full-blown crisis. With Flash Thompson offering shelter—though it’s in Queens, far from Peter’s usual stomping grounds—he’s left searching for a place to stay, only to be thrown into a new kind of danger with the arrival of the enigmatic Mindworm, a mutant whose powers twist emotions in unpredictable ways. Written by Gerry Conway and brought to life by Ross Andru’s dynamic art, with Frank Giacoia’s inks and Petra Goldberg’s colors, this issue captures Spider-Man’s vulnerability with sharp realism, while Gil Kane’s cover delivers a striking, memorable image.

History

The issue was written by Gerry Conway during his landmark run on the title, which spanned issues #111–149 and included the death of Gwen Stacy; at the time Conway took over as Marvel's primary Spider-Man writer at just nineteen years old, succeeding Stan Lee on one of the publisher's flagship books. Interior art was pencilled by Ross Andru with inks by Frank Giacoia and Dave Hunt, while the cover was rendered by Gil Kane with inks by John Romita Sr., under editor Roy Thomas. A notable behind-the-scenes footnote: according to the Marvel Appendix, artist Ross Andru used an actual house in the Far Rockaway neighborhood of Queens as reference for Mindworm's lair, which reportedly attracted curious neighborhood kids hoping to spot the large-headed villain — prompting Marvel to issue an apology in the letters column of a subsequent issue (#149).
