Bruce Banner was a scientist working on the gamma bomb when he noticed a young boy out on the test range. He rushed out into the test site and heroically pushed the boy into the protective trench, saving him from the blast. As a result, Bruce was exposed to extreme amounts of gamma radiation that altered his DNA structure, causing him to become a giant green (sometimes grey) monster of incredible power whenever he became angry. His sometimes girlfriend, Betty Ross, seems to be the only thing to calm the Hulk back into Banner form, and he is often pursued by her father, General Thunderbolt Ross, who seeks to stop the Hulk's rampages, hoping to bring the Hulk to justice or destroy him altogether. Because of this, Bruce is often on the run, trying to find a cure for his problem and keep calm as much as he can.
