The Gas Gang were a group of short-lived fictional robots created in the Metal Men universe, from the Metal Men story "The Day Doc Turned Robot!".


The story begins where the previous story "Menace of the Mammoth Robots!" left off. After dislodging a meteor from his ship's hull and rescuing the lone female robot, Platinum Platinum, Dr. William "Will" Magnus had his spacesuit perforated by cosmic rays. The effect was that during their return trip to Earth, "Doc" Magnus became a robot himself, displaying none of the actual human and humane feelings toward his Metal Men or anything, even to the point of denying the Metal Men the opportunity to rescue another rocketship in distress. After they disobeyed orders and rescued the ship, Doc Magnus threatened to melt down his creations. For his own protection, after landing the Metal Men locked him in his lab and began experimenting on ways to make him human again.

However, while they were busy with one failed experiment after another, the lab door burst open and Doc Magnus introduced his new robots, the Gas Gang. Unlike the Metal Men, these were based and named by the gases: Oxygen, Helium, Chloroform, Carbon Monoxide, and Carbon Dioxide. Whereas the Metal Men were approximately the same size as Doctor Magnus, the Gas Gang were anywhere from one-third to twice his size.

On Chloroform's initial attack, it caused the Metal Men to break out in fits of hysteria: Nitrous Oxide, which Doc Magnus said was chloroform's initial effect. Before Lead could wall them off, Mercury literally "broke up laughing", opening Oxygen to attack and causing the Metal Men to begin to rust. During the chase Carbon Monoxide attempted to poison them with fumes, while Carbon Dioxide attempted to freeze them. The chase ended in one of the labs where Gold was attempting heat conduction on the others as a possible cure for their creator. As Helium expanded and cornered the Metal Men, Platinum got Gold to repeat the experiment, stretching and transforming himself into a large cage and trapping the Gas Gang. When he connected himself to the high-voltage conductors, he melted the Gas Gang and converted them all to steam. That was when they discovered Doctor Magnus had been trapped in there with them, and as it turned out is what cured him and made him human again.


  • Oxygen - A Gas Gang member in the form of a walking oxygen tank.
  • Helium - A Gas Gang member in the form of a rubberized container that could expand.
  • Carbon Monoxide - A Gas Gang member in the form of a walking lit.
  • Chloroform - A Gas Gang member in the form of a walking cylindrical tank perforated with holes from which it emitted its gas.
  • Carbon Dioxide - A Gas Gang member that resembles an anthropomorphic dry ice crystal.

In other media[]


  • The Gas Gang appeared in the Batman: The Brave and the Bold episode Clash of the Metal Men with Oxygen voiced by Brian Bloom, Carbon Dioxide voiced by Hynden Walch, Hydrogen voiced by Lex Lang, Helium voiced by Bill Fagerbakke, and Chloroform and Nitrogen having no dialogue. This version of the team is altered somewhat from the original: Hydrogen (an explosive gas) is added, Carbon Dioxide is renamed Nitrogen, and Carbon Monoxide is renamed Carbon Dioxide. This version of the Gas Gang are Dr. Magnus' fellow scientists who were turned into gaseous forms following a lab accident trying to use the experiment for themselves and then develop the right gas to cause volcanoes to erupt causing mass destruction. They kidnap Dr. Will Magnus in order to form robotic bodies to store their fading bodies. They fought Batman and the Metal Men and ended up defeating them. Dr. Magnus reluctantly made them robotic bodies to store their gaseous forms when they tricked him into believing that he was responsible for their condition. They then strapped a chemical container to Dr. Magnus and slowly lowered him into a volcano so that the heat can trigger the chemical container and set off the volcano. When their powers were too much for the Metal Men, they formed around Batman to form an armor. After taking a beating, the Gas Gang also combined and turned the tide against Batman and the Metal Men. Batman threw a torch at the combined Gas Gang exploding their robotic bodies and combined their gas forms into a deadly gas cloud. While Batman went after the Gas Gang, the Metal Men saved Dr. Magnus. Batman set his Batplane to self-destruct destroying the Gas Gang.
