Brains is the leader of the Gang, a quartet of costumed criminals who grew up together in poverty on the South Side of Chicago, and are determined to make themselves wealthy by any means necessary, and are employed by the criminal organization called the Council.
Brains possesses no apparent super powers, yet is a brilliant criminal strategist and inventive genius. The Gang is defeated by Supergirl shortly after she relocates to Chicago, but Brains escaped capture and remains at large (DNAS No. 4, Feb 1983: "Hail, Hail, the Gang's All Here!").
