A new Hulkbuster model, designed to fight against the Hulk, who at that time considered Tony Stark responsible for sabotaging the Gamma bomb and, as a result, causing the explosion that transformed Bruce Banner. The armor is assembled inside Stark's car or from actual parts of it and it is equipped with the most advanced arsenal to stop the green Goliath, namely Gamma blades, which produce a line of radiation to cut through even Hulk's skin and a powerful 'shock-and-awe' barrage using repulsors and ultrasonics. Though it was possible that this suit would've been capable of stopping the normal Hulk, it was no match for the smarter, Extremis-enhanced Hulk.
