While his chum Hawkman faced off against a horde of Silver Metal Men, Earth-Two's Atom dealt with their Iron brethren. The creatures consuming the metallic substance and adopting its abilities, wrought havoc on subway systems. How would the Mighty Mite deal with this threat to transportation everywhere. Using his noggin, naturally!
Using a spray of oxgyen, the Mighty Mite is quickly able to rust out the bodies of these critters, leaving them "dead pigeons"... so to speak!
Earth-One's Iron of the Metal Men was the powerhouse of his team, helping them out of many scrapes. One attribute he didn't possess, however, was adaptability and relied heavily on his scrappy nature. When faced with rival robot Cobalt on one occasion, he realized how limited he was when not using his head along with his hands! Still, he was always a reliable pal to his computerized comrades.
