The IG-series was a series of droids. The InterGalactic Banking Clan maintained an army of IG lancer droids. One model of IG was a set of five identical assassin droids manufactured by Holowan Laboratories during the final decades of the Galactic Republic. Only moments after their activation, those robots slaughtered their constructors and escaped their laboratories to roam the galaxy. One of them was IG-88, who functioned as a bounty hunter during the Galactic Civil War.
