She-Hulk (Jennifer Walters) is a fictional superheroine appearing in American comic books published by Marvel Comics. Created by writer Stan Lee and artist John Buscema, she first appeared in Savage She-Hulk #1 (February 1980). A cousin to Dr. Bruce Banner, Walters once received an emergency blood transfusion from him when she was wounded, which led to her acquiring a milder version of his Hulk condition. As such, Walters becomes a large powerful green-hued version of herself while still largely retaining her personality; in particular she retains her intelligence and emotional control, though like Hulk, she still becomes stronger if enraged. In later issues, her transformation is permanent.
