Plastic Man #37 (1952)

Plastic Man and his aide Woozy stumble upon a bizarre situation after a picnic lunch, when they’re suddenly confronted by giant, intelligent ants that have escaped from a hidden underground lab. The ants, grown to monstrous size through atomic experimentation, are now on the move—threatening both the scientists who created them and the heroes who’ve stumbled into their domain. As Plastic Man scrambles to outwit the towering insects, he realizes the true danger isn’t just their size, but the twisted minds behind their creation.
