“Doom in the Heartland!”

In "Doom in the Heartland!", Superman answers a call in Kansas City, only to find the Doom Patrol already battered and broken—defeated by Metallo. Meanwhile, Lana brings Ma and Pa Kent face-to-face with Supergirl for the first time, setting off a quiet moment of family connection amidst the rising tension. Written by John Byrne and illustrated by Byrne with inks by Karl Kesel and John Byrne, this 1988 issue blends heartfelt domestic scenes with urgent superhero action, all rendered in vivid colors by Petra Scotese and lettered by John Costanza, with a striking cover by Byrne.
