General Thaddeus “Thunderbolt” Ross once met with Dr. Bruce Banner, the boyfriend of his daughter, Betty, with an interesting proposition. Ross aims to recreate the results of a World War II-era program in order to create an army of super soldiers. Had it been successful, he would’ve found a way to make humans immune to gamma radiation. Unfortunately, the experiment failed, and the radiation caused Banner to transform into a giant, raging beast for brief periods whenever his heart rate exceeds 200 beats per minute. Five years have passed since that day, and Banner now works at a bottling factory in Rocinha, Rio de Janeiro. He is determined to seek a cure for his condition, secretly corresponding with an unidentified individual known as Mr. Blue. He has not transformed in five months, but his peaceful existence is not to last.
