Hulk and Power Pack #2

In "Energy Crisis," Power Pack faces their most electrifying challenge yet when Katie absorbs a strange energy known as Specimen Z during a Hydra raid. With their dad and Bruce Banner hosting a press conference on alternative energy, the mysterious force awakens as the Zzzax, forcing Hulk and the kids to team up before the energy goes out of control. Written by Marc Sumerak and illustrated by David Williams, with colors by Naoko Kawano and Gurihiru, this 2007 issue blends high-stakes science with the Power Pack's signature heart, all wrapped in a cover by David Williams.
