The four members of the Gang were friends while growing up in the impoverished streets of Chicago's South Side. They were willing to commit crimes as a means of escaping from their neighborhood, but they didn't want to end up jailed or worse. So they formed "The Gang", laying out a series of rules and lines to not cross (such as killing), and each one developed their personal talents: Brains studied hard, Ms. Mesmer learned hypnotism and Kong and Bulldozer worked out. They kept themselves in their clubhouse's basement until they were ready, and associated with Lester Adams, a member of The Council.
Their first job-for-hire was stealing an experimental satellite at the Chicago Aerospace Technology Show. Supergirl showed up as they were taking the device away, but Ms. Mesmer's hypnotic suggestions kept her at bay while the Gang ran away.
The Gang clashed several more times with Supergirl until she managed to put them away.
