Super Caveman

The mighty caveman from Krypton, a Stone Age survivor of Superman’s home planet endowed with superhuman powers identical to Superman’s, who awakens to renewed life after arriving on Earth in a state of suspended animation in the heart of a meteor. Super Caveman, hopelessly out of place on an alien planet in an alien era, eventually dies from the combined effects of his recent exposure to Kryptonite and the bombardment of cosmic rays he endured during his journey through space (WF No. 102: “The Caveman from Krypton!”).
