She-Hulk

Jennifer Walters, the meek and mousy lawyer cousin of Bruce Banner, was the daughter of Sheriff Morris Walters. Agents of Nicholas Trask, a crime boss who had crossed paths with her father, shot and seriously wounded her on a day when her cousin was in town. Bruce gave her a blood transfusion, as no other donors of her blood type were available; the radioactive blood mutated Jennifer as it had her cousin, transforming her into the She-Hulk.
