The Pack

Based out of Zandia, the Pack are some of the most dangerous mercenaries the world has ever seen.  Originally all independent operators (except for Jackal and Hyena), they were brought together for a specific mission several years ago, and decided they could be much more profitable if they worked together.  The accomplished several missions and were eventually hired by Intergang to deal with Superman.

Their initial outing, even with Intergang weapons, proved to be a spectacular failure.  Following, Intergang sprung them from prison and outfitted them with upgrades that included power armor, genetic engineering, and cybernetics.  While they still failed to be a match for Superman, they continued their criminal careers.  Even without their upgrades and powers, each member of the Pack is a deadly fighter and killer, skilled in various fighting techniques and weapon-usage.
