Following the first clip that debuted last week from Marvel Iron Man & Hulk: Heroes United, Marvel Studios has released seven new photos featuring these superheroes in action. Adrian Pasdar lends his voice to Tony Stark/Iron Man, while Fred Tatasciore voices Bruce Banner/Hulk, as they team up to defeat the electrical villain Zzzax (Dee Bradley Baker). This continuation of the Marvel's The Avengers initiative debuts on Blu-ray and DVD December 3.

The Invincible Iron Man and the Incredible Hulk have joined forces to save the Earth from its greatest threat yet. When two Hydra scientists try to supercharge a Stark Arc Reactor with Hulk's Gamma Energy, they unleash a being of pure electricity called Zzzax, and he's hungry for destruction. Together, Iron Man and Hulk are the only force that stands in the way of the Zzzax's planetary blackout. But first the super heroic duo will have to get through snarling Wendigos, deadly robots and the scaly powerhouse, Abomination. Can two of Marvel's mightiest heroes find a way to work together without smashing each other before time runs out?
