Zha-Vam

History: Zha-Vam was created by the ancient Greek gods in the past, when they realized Superman would eclipse their fame in the future. They sent Zha-Vam to battle and humiliate Superman, in order to reclaim their preeminent position as objects of public adoration. Zha-Vam confronted and humiliated Superman through the use of his many powers; Superman was turned into stone once and defeated through the use of kryptonite on another occasion.
