The Metal Men were created by Doctor Will Magnus, a young, successful, and inventive genius. By the time of the Metal Men's creation, Magnus had already amassed a personal fortune through patent royalties - much of which he reinvested in his research. The result of one of his projects was a robot made of platinum, female in form, whom Magnus nicknamed Tina.
Unlike conventional robots limited to certain programmed tasks, Tina was powered by a responsometer, a nuclear powered microscopic activator. Not only did this device animate her body, but it endowed the robot with distinct and decidedly human intelligence and personality. It was due to the latter trait that Magnus decided to put Tina in the Science Museum; his activator was too perfect and Tina, to his mind, too much of an annoyance.
Before Doc Magnus could attend that chore, he was alerted to the menace of a monstrous prehistoric winged creation recently released from its glacial resting place. To combat this radioactive menace, Magnus created an entire team of responsometer- powered robots, each forged from a different metal, each with its own unique strengths. These robots he dubbed his Metal Men.
Like Tina before them, each of the new robots possesses very individual personality traits. Intelligent and analytical, Gold is the team's acknowledged leader. His golden form has all the physical properties of the metal from which he has been forged: he can stretch into a thin wire miles long, or flatten into a sheet 4 millionths of an inch thick.
Lead is rather slow, but big hearted and reliable. His ability to shield against harmful rays and radiation are a frequent and useful asset to the team.
Iron is the Metal Men's strongman. Good natured and friendly, he is the group's powerhouse. He is able to be shaped and formed into an infinite variety of objects to assist the team in its missions.
Mercury is proud, egotistical, and fond of telling anyone who will listen that he is the only metal that is a liquid at room temperature.
Tin is the smallest and weakest of the Metal Men, though he is possibly the bravest soul, and is always willing to risk his existence to aid anyone in danger. As a result of his feeling inadequate, Tin stutters, although this impediment often vanishes in the heat of battle.
A further unofficial member of the team was "Nameless", a robot built by Tin. Shy and withdrawn, Nameless was Tin's "girlfriend" until her destruction in battle.
In the course of their career, the Metal Men have fought a variety of foes, most of them robots created for evil. Perhaps their most unusual and deadliest for is Chemo - a walking stew of chemical waste in gigantic humanoid form, mindless and bent on destruction. Among their other foes are the Missile Men, the Gas Gang, B.O.L.T.S., Doctor Yes, and the Plastic Perils.
The Metal Men's exploits have brought them worldwide acclaim. Doc Magnus was constantly struggling with his desire to be rid of these human-like robots and their annoying squabbles and the world's need for their unique abillities. He watched as they were repeatedly destroyed and then brought back to life again.
Magnus eventually retreated into his vast, fully automated research facility and immersed himself in his work. However, the strain proved too much for him and he had a nervous breakdown.
While Magnus recovered, the Metal Men continued to fight as a team. When he was fully back to himself, Magnus rebuilt the body of Robotman, the only survivor of the Doom Patrol at that time.
More recently, Magnus has returned to the Metal Men and they continue to embark upon new adventures. The Metal Men are also seen in the New Doom Patrol series second feature. Dr. Magnus and his Metal Men moved out of California and the government put them in Illinois. The people of Illinois and the residents in the neighborhood hate the Metal Man and they want them to leave. Dr. Magnus is trying to get the Metal Men to drive a car and get their license for them but trouble still lies ahead for the Metal Men. The house where Will Magnus lived was destroyed by the TV actor Robot Hunter. He was going to kill the Metal Men by detonating a bomb placed inside. He was unsuccessful as Magnus and the Metal Men were outside of the house when the explosion occurred. The Metal Men and Will Magnus will have to start all over again to find a new house to live in. The Metal Men's whereabouts are unknown at this time. The Metal Men will be appearing in the new series called Justice League: Generation Lost.
