Jennifer Walters is a talented lawyer and the cousin of Bruce Banner, the Hulk. After being shot by a mobster and seriously injured, she was saved by a blood transfusion from Bruce, and his gamma-irradiated blood mutated Jennifer into the She-Hulk, kicking off her adventuring career. Jen wasn't as strong as her cousin, but she maintained her intelligence as She-Hulk, soon learning to control her transformations and even embracing her green form. Throughout the years, Jen fought for justice in court and on the streets, developing great rivalries and friendships and growing to become a respected leader. She worked for the District Attorney and also fought crime as a member of countless teams, namely the world-famous Avengers and Fantastic Four. Jen was originally much like her cousin in her Hulk form, being ill-tempered and even violent (although with more self-control).With time, however, she became a fun-loving, kind, empathetic, yet still feisty woman who frequently uses humor when fighting. Walters has made it clear that she prefers not to kill those she fights, especially if her enemies have already been rendered unable to fight.Walters is also known for charitable works related to her own mistakes and actions, such as the disaster relief organization she aided after almost destroying a small town in her savage form. Walters is known as an idealistic lawyer, that has been known for championing the rights of minorities and the rights of individuals against corporations. Walters' beliefs have sometimes led to difficulties regarding her stance on unjust laws such as the Superhuman Registration Act, and her cousin's exile to space by those she was unable to seek a lawful resolution from. Jennifer has at times become dependent upon her powers, viewing her She-Hulk form as being better and more truthful to who she is than that of Jennifer Walters, and opting to remain transformed as much as possible. This insistence of remaining as She-Hulk has caused problems in her relationships at times, such as with John Jameson, who preferred her to stay as Jen. Despite usually confident about her beauty and looks,Jen appreciates the additional strength and freedom of her bulkier forms.
