Krieg is a major antagonist and Minion of Dr. Calixto. Krieg is a loudmouthed, impulsive, bloodthirsty and arrogant cyborg who hails from Germany, despite sounding and acting more like an American warmonger than a German soldier. Despite being Dr. Calixto’s minion, he wishes to kill him and take over the world under a machine empire. But, a cyborg can only dream. He is made from a scientifically enhanced Metal called KriegSteel, which can absorb kinetic energy and add on to Krieg’s strength, which allows him to become stronger through damage.
