Lee Portman was a 300-pound man from Australia who emigrated to the United States, where he started a crime spree wielding a boomerang, until he was stopped by
Kid Colt. Later, he encountered the criminals
Doctor Danger and
Bennington Brown, and the three were contacted by
Iron Mask, who invited them to join his newly-formed
Circus of Crime. They accepted, but the gang was stopped by Kid Colt. Fat Man later joined the second incarnation of the Circus under Iron Mask, which was put together to form a supervillain team, inspired by events triggered by the time-travelling
Kang and
Avengers. But before their gang could gain momentum, the bandits were stopped by
Rawhide Kid,
Two-Gun Kid,
Phantom Rider and the time-stranded
West Coast Avengers and sent to jail. ==References==
