Gas Gang 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 ala Nitrous Oxide (Laughing Gas) 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 (called "CM" by Carbon Dioxide) attempted to poison them with fumes, while Carbon

Materials such as LPG and LNG are complex mixtures often without precise chemical composition that often also changes whilst stored.
