She-Hulk (Jennifer Walters) is a fictional character appearing in American comic books published by Marvel Comics. Created by writer Stan Lee and artist John Buscema, she first appeared in The Savage She-Hulk #1 (cover-dated February 1980). 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 she largely retains her personality, in particular the majority of her intelligence and emotional control. Like Hulk, she 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.
She-Hulk has been a member of the Avengers, the Fantastic Four, Heroes for Hire, the Defenders, Fantastic Force and S.H.I.E.L.D. As a highly skilled lawyer who became a superhero by accident, she frequently leverages her legal and personal experience to serve as legal counsel to various superheroes and other metahumans.
