One of the most colorful super-hero teams of the early 1960s, the Metal Men are six shape-shifting robots whose personalities are based on their metals: Hot-tempered Mercury, timid Tin, thick-headed Lead, etc. Invented by eccentric scientist Dr. Will Magnus, the team is ready to give their all - including their artificial lives - to protect mankind. In these tales, never before reprinted in color, the Metal Men take on the Gas Gang, including Helium, Oxygen, Chloroform and more, save lives at the "Playground of Terror," try to stop the deadly rain of "The Missile Men," and battle Chemo, a giant, human-shaped vat filled with deadly chemicals.
