In "Worlds At War," a desperate scientist attempts to secure global peace by summoning a Martian threat, only to unleash a full-scale invasion that nearly levels New York City. Captain America, ordered by the Martian warlord to deliver an ultimatum to the U.N., instead turns the tide by reactivating the planet mover to send Mars back to its orbit—leaving the Martians stranded and unable to survive on Earth. With art by Ken Bald and inks by Vince Alascia, and a cover by Al Avison, Carl Burgos, and Vince Alascia, this 1949 classic delivers a timely, thought-provoking tale of unintended consequences.

In "Worlds At War," a desperate scientist’s attempt to enforce peace by conjuring a shared threat backfires when he brings Mars dangerously close to Earth, unleashing a Martian invasion that lays waste to New York. Ordered by the Martian warlord to deliver an ultimatum to the U.N., Captain America instead races to the scientist’s lab, reactivating the planet mover to send Mars back—trapping the Martians in a hostile void where they can’t survive. The story’s quiet triumph lies in its moral: even the most extreme measures can’t defeat evil without consequence.
