She-Hulk is a character appearing in American comic books published by Marvel Comics. Created by writer Stan Lee and artist John Buscema, the character first appeared in The Savage She-Hulk #1. Walters is a lawyer who, after an injury, received an emergency blood transfusion from her cousin, Bruce Banner, and acquired a milder version of his Hulk condition. As such, Walters becomes a large, powerful, green-hued version of herself. Unlike Banner in his Hulk form, Walters largely retains her normal personality in her She-Hulk form, in particular the majority of her intelligence and emotional control. Furthermore, though she's much taller in her She-Hulk form, Walters's body mass is just as dense as that of her normal human self. In any case, like Hulk, She-Hulk is still susceptible to outbursts of anger and becomes much stronger when enraged. In later series, her transformation is permanent, and she often breaks the fourth wall for humorous effect and running gags, as the first major Marvel character to do so frequently, ahead of the more famous fourth wall breaker Deadpool.

Stan Lee was an American comic book writer, editor, publisher and producer. He rose through the ranks of a family-run business called Timely Comics which would later become Marvel Comics. He was Marvel's primary creative leader for two decades, leading its expansion from a small division of a publishing house to a multimedia corporation that dominated the comics and film industries.
