Sensational She-Hulk by John Byrne Omnibus #1

She-Hulk is captured by SHIELD to make sure she won't become the type of menace caused by her more famous and violent cousin, but the plan goes wrong when the helicarrier is menaced by a horde of sentient roaches. The helicarrier goes down in the mayhem and in keeping the whole thing from blowing sky high, She-Hulk is exposed to a heavy dose of radiation that prevents her from changing into her alter-ego Jennifer Walters ever again.
