Hulk, uncontrollable green monster and scientist, Dr. Bruce Banner
Dr. Robert Bruce Banner is a quiet, reserved and rather feeble physicist. Following exposure to gamma rays, he is transformed into the Hulk, an excessively muscular, green-skinned giant with extraordinary strength.
Banner and the Hulk exist in the same individual, with the latter only manifesting itself when the former is subjected to high levels of stress. Once Banner becomes Hulk, he embarks on destructive rages, using his seemingly limitless physical strength to wreak havoc.
