SHE-HULK, art by George Pérez. Joined in AVENGERS #222 (Jul 82).

HISTORY: She-Hulk: Lawyer Jennifer Walters debuted in Savage She-Hulk #1 (February, 1980) as the cousin of Dr. Robert Bruce Banner aka the Incredible Hulk.

After being critically injured during an assasination attempt, Bruce gave her a blood transfusion, but his gamma radiation-mutated blood turned her into a female version of the Hulk who could control her transformations and retained her intelligence when becoming She-Hulk. In The Avengers (vol. 1) #221 (July, 1982), she joined the Avengers and later replaced the Thing as a member of the Fantastic Four.

While trying to shut down an atomic pile that was about to explode, she was exposed to a high dose of radiation that subsequently prevented her from transforming back to Jennifer Walters, but it apperead she didn't care at all, since she had preferred being She-Hulk for a long time already. After leaving the Fantastic Four, she used to be a reserve member of the Avengers and concentrated on her career as a lawyer.

After having almost married her long-time lover Wyatt Wingfoot, she was a member of the Fantastic Force and later worked for the Heroes for Hire.

During the course of the "Kang Dynasty" storyline, she finally returned to the front line and rejoined the Avengers as a full-time member in The Avengers (vol. 3) #58 (November, 2002).

POWERS & WEAPONS: In superhuman form, the She-Hulk can life (press) at least 75 tons. She is continuing to train to lift even greater weights and the uppermost limit of her potential strength is as yet unknown. Since Jennifer Walters' close genetic resemblance to her cousin, Bruce Banner, enable her body to transform without the direct exposure to the gamma radiation that affected the Hulk's body and to transform into a being similiar to the Hulk. (Intense gamma radiation would either kill most other people or induce harmful mutations in them). Because the catalyst for her transformation was indirect, the She-Hulk's superhuman form is not nearly as powerful as the Hulk's.

Originally, as with the Hulk, the She-Hulk could transform back and forth between her human and superhuman forms. As with the Hulk, an increase in the level of epinephrine (known as adrenaline) due to stress triggered a chemical extraphysical process that added, in some unknown way, in the She-Hulk's case 540 pounds of bone, marrow, and tissue to her body. The total transformation took from 15 seconds to as long as three minutes, determined by the degree of stimulation achieved by the initial surge of epinephrine. Shortly after the transformation, the amount of epinephrine declines to normal reduced levels. The She-Hulk could trigger her transformations back and forth by an act of will far more easily than the Hulk could. However, recently, due to the mutagenic effect of further exposure to intense radiation, the She-Hulk is now unable to change back to her "normal" human form.

Unlike the Hulk, the She-Hulk retains her normal intelligence and personality in her superhuman form. (However, her enjoyment of being the She-Hulk has caused Walters to become more uninhibited in her behavior in the time since she first became the She-Hulk). Because she retains her normal intelligence, the She-Hulk is incapable of the primal rages that triggers increased levels of strength and body efficiency in the Hulk.

The She-Hulk's powerful leg muscles enable her to leap straight up to a height of 600 feet, or to jump a distance of 1000 feet.

The She-Hulk's body possesses a high degree of imperviousness to injury, pain and disease. The She-Hulk's skin is capable of withstanding extremes of temperature, from 3,000 degree Fahrenheit to negative 190 degree Fahrenheit, and great stresses and impacts without puncture wounds or lacerations (she can withstand direct hits by field artillery cannon shells). The She-Hulk's highly efficient physiology renders her immune to all terrestrial diseases.

NOTES: The "costume" she's wearing on the covers of JLA/Avengers issues 1&2 was created by George Pérez and was first seen in The Avengers (vol. 3) #4 (May, 1998), the version colored as seen inside issue 1, however, was first seen in The Avengers (vol. 3) #27 (April, 2000).
