She-Hulk, like Hulk, is a Marvel creation thought up by Stan Lee having been introduced to the Marvel universe in 1980, and is now a firm fixture. She has appeared as a member of the Avengers, Fantastic Four, Heroes for Hire, Fantastic Force and S.H.I.E.L.D.
Jennifer Walters became She-Hulk after she was wounded and received an emergency blood transfusion from her cousin, Bruce Banner aka the Hulk of course. This caused her to acquire a milder form of his Hulk affliction. Since she retains the majority of her own personality (she’s a highly talented lawyer) whilst at the same time becoming larger, greener and stronger, she is like a more refined version of the Hulk.
Jennifer Walters is, as mentioned above, a talented lawyer although she is somewhat shy. Thanks to the gamma radiation in her blood, she possesses superhuman strength as well as incredible speed agility, stamina and reflexes. As she has not been so strongly exposed to the radiation as Bruce Banner, she retains more of her personality and as such is a more confident, feisty and powerful version of herself.
In addition to her powers listed above, she also has these pretty awesome bodily attributes that include: extraordinary resistance to pain and disease, resistance to extreme temperature, and she can also heal herself, enabling her to completely recover from any wound or injury rapidly.
Added on these radiation-given gifts, She-Hulk has been trained in hand to hand combat by Captain America himself, making her a fearsome opponent. As a talented lawyer she also fights cases on behalf of superheroes. As a final boon, she is also a skilled pilot.
With so many talents, as well as looking like some sort of green Amazonian warrior, what’s not to love about She-Hulk? And with recent rumours of a She-Hulk cinematic debut, you can be sure that you will be seeing a whole lot more of this green Goddess.
