She-Hulk (real name Jennifer Walters) is a superheroine from Marvel Comics. The cousin of Bruce Banner, aka the Hulk, Jennifer was a district defense attorney who upon getting injured in an accident was given a blood transfusion by Bruce. However, due to his highly gamma-irradiated blood, Jennifer's DNA was mutated and she in turn transformed into a tall, incredibly strong, green skinned yet still beautiful monster of a woman. However, unlike her cousin, who as the Hulk varied in intelligence and was naturally aggressive, Jennifer fully retained her full consciousness, and thus used her newfound powers to become a superheroine.
She-Hulk was created by Stan Lee and John Buscema. She is the final major character created by Stan Lee.
