In "Battle of the Moon Monsters!", the Kull’s quiet vigil against cosmic anti-matter blotches takes a dangerous turn when one of their lighthouses drifts into Earth’s solar system. Two Earthmen stumble upon the device, only to be captured by the Zarran—ancient foes of the Kull—whose twisted plan turns the lighthouse into a weapon of mass radiation. Written by Gardner Fox and illustrated with dynamic flair by Mike Sekowsky, with inks by Frank Giacoia, this 1959 DC adventure blends alien intrigue and high-stakes survival. Gil Kane’s striking cover captures the tension of the moment, drawing readers into a story where curiosity leads to captivity—and unexpected redemption.
