She-Hulk (Jennifer Susan Walters) is a Marvel Comics superheroine. Created by writer Stan Lee and artist John Buscema, she first appeared in Savage She-Hulk #1 (February 1980).
She-Hulk has been a member of the Avengers, the Fantastic Four, Heroes For Hire, Defenders, Fantastic Force, and S.H.I.E.L.D. A highly skilled lawyer, she has served as legal counsel to various superheroes on numerous occasions. Her cousin is Bruce Banner, better known as The Incredible Hulk.A transfusion of gamma-irradiated blood from her cousin Bruce Banner (the Hulk) granted Jennifer Walters superhuman powers. In her She-Hulk form, she possesses immense superhuman strength, which makes her one of the strongest known women in the Marvel Universe. It has sporadically been stated to increase further from fear, or anger. Despite this, she is no match for her cousin. In addition the character has been listed as possessing slightly superhuman speed, agility, and reflexes, as well as superhuman stamina that enables her to work at peak exertion for up to a day without tiring. Despite this, she is no match for her cousin. However, unlike Hulk, her personality and intelligence are less affected when she transforms into the She-Hulk, although she becomes more self-confident and assertive. For a long time, She-Hulk could not revert to her original human form.
As She-Hulk, Walters is exponentially stronger than she is in her Jennifer Walters form; therefore any extra strength gained as Jennifer Walters through intense physical training will be amplified, making her She-Hulk form even stronger. After being defeated by the Champion of the Universe, She-Hulk exercised for several months in her Jennifer Walters form, resulting in a significant gain in strength and muscular mass in her She-Hulk form and allowing her to soundly defeat the Champion in a rematch. At this time she was able to effortlessly sustain the Thing's maximum weight with a single arm, while her strength was greatly restrained by a "Jupiter suit." Her strength has since receeded, but remains comparable with that of Hercules.
She-Hulk's body is superhumanly durable and impervious to high levels of force, pain, and disease: her skin can withstand extremes of temperature, as well as tremendous stresses and impacts without puncture wounds or lacerations. Despite this, she has been proven to be highly ticklish, as she was once tickled by the Hulk Robot during a battle between a rag-tag group of villains and the Avengers during the Acts of Vengeance.Her enhanced physiology renders her immune to all terrestrial diseases. She-Hulk also possesses a healing factor, which enabled her to completely recover, within minutes, from a skewering by the Wendigo.
