Unlike Hulk, Jennifer's personality and intelligence are less affected when she transforms into She-Hulk, although she becomes more self-confident and assertive. In court it was proven that her gamma mutant form also has fewer inhibitions, as proven during a trial for the Leader; for example, while Jennifer Walters has only had a few sexual partners, reading back a list of She-Hulk's conquests took considerable time. For a long time, She-Hulk could not revert to her original human form, but that turned out to be psychosomatic due to her not actually wanting to.
