I had no clue, the more you know...She-Hulk has been an established Marvel character since the '80s.
She Bruce Banner's lawyer cousin, who becomes She-Hulk after a blood transfusion she receives from Bruce.
There are more fitting heroes to introduce, if Disney only wants to please the PC crowd. The new Ms Marvel is a Pakistani, Muslim, teen aged girl. That's ticking off 3 boxes at once, while hitting the "teenage role model" target as well.
