History
The history of this incarnation of Zzzax is most likely identical to that of his Earth-616 counterpart.
At some point, he was captured in some sort of containment unit, and came in the possession of Hydra, who labelled him "Specimen:Z". They planned to unleash him in a power plant in New York. Power Pack interfered, and Katie Power used her powers to absorb Zzzax into her body before he could cause any damage. She didn't know at the time however that 'specimen:Z' was in fact a living creature.
Later, Power Pack attended a demonstration by their father, James Power, and Bruce Banner. The two men had invented a electromagnetic field generator that would revolutionize the process of generating electricity for big cities like New York. When Banner turned it on however, Zzzax escaped from Katie and used the generator to reform his body. Banner turned into The Hulk to fight him and was soon joined by Power Pack. They first destroyed the generator, but this was not sufficient enough to stop Zzzax. Julie eventually figured out a way to stop him; by using a metal cable and the local pond, she and Hulk were able to short out Zzzax, beating him for now.Attributes
