Marga the Panther Woman

Ultra-violent, pre-Comics Code Authority comic story featuring early Jungle Girl character Marga the Panther Woman from Science Comics #6 (July 1940). In a few short appearances Marga's character would change from an uncontrollable, insane loner who identifies with the animals to rationalize her serial-killer nature into a standard jungle princess super-hero.

While the latter characterization is a lot more family-friendly it is a bit boring. The Marga as depicted in Science Comics #6 is not PC, decidedly unkind to animals, a sociopath and a whole lot more interesting.
