The Marvel Comics universe is full of hulks these days. The original and most well-known, of course, is Doctor Bruce Banner, whose experiments with gamma radiation unleashed The Incredible Hulk. When Dr. Banner's cousin, Jennifer Walters, was near death, he gave her a blood transfusion to save her life. In doing so, he not only revived her, but also gave her the power to transform into the She-Hulk.
