Metalo
Metalo
A villain of awesome power, a renegade inventor --discoverer of "the most powerful metal on Earth" as well as a miraculous "strength serum"-- who, clad in a special armored suit of his own design, is impervious to bullets, can fly through the air, and possesses monumental super-strength equivalent to Superman's.
Operating froma subterranean hideaway beneath the main tent of the Farnham Circus , somewhere on the Metropolis waterfront, Metalo stuns the city with a series of spectacular crimes --including the theft of an entire mail car from the Metropolis train terminal, and an attempt to extort $5,000,000 from the city's businessmen by threatening to destroy Metroplolis --until finally, in a climactic encounter with Superman, "the very mountains tremble and are rent asunder by the colossal battle of these two super-powerful opponents ...!"
Believed dead after plummeting into a yawning lava-filled crevice at the peak of the awesome battle, Metalo manages to cling to an outjutting rock and although thwarted in his evil undertakings, to survive (WF No.6, Summer 1942: "Man of Steel versus Man of Meral!").
