Women in comics have been a staple since the beginning, but they've often taken a back seat to their male counterparts. Comic book publishers have tried to correct the imbalance between male and female superheroes in many different ways, both creating original characters and inventing gender-bended iterations of male heroes.
Gender-bending in comics has not always been met with enthusiasm, but there are quite a few characters who have managed to step out of the shadows of their male forbears and reinvent the idea of what a hero can be. Some gender-swapped characters have become equally, if not more, popular than the original incarnations. For instance, Carol Danvers is now better known as Captain Marvel and is more popular than the original Mar-Vell Others have fostered a smaller but fiercely dedicated fanbase.
Jennifer Walters is the cousin of Bruce Banner who eventually becomes She-Hulk. Originally from Los Angeles, Walters went to UCLA to become a lawyer. She was quite timid in her normal life, but was a fierce lawyer who got on the bad side of many criminals. Eventually, some gangsters attempted to take out Walters, and she was rushed to the hospital after they fired at her. Bruce just so happened to be in town on that day and forced his way into her hospital room, where he gave her a life saving blood transfusion.
There were side effects, however. When a group of thugs came to her hospital room to finish the job, the gamma particles in the transfused blood turned her into a big, green fighting machine. Her confidence grew with her stature, and for a while she preferred staying in her Hulk form rather than live in her normal body.507108Was this a good swap?
