A/N: this is just something from a recent article and I really don't want to spend time taking a screenshot and posting it on my computer. So the bolded words are what are from the article.
"A character breakdown for the show's lead has been revealed by The Illuminderi, and it confirms that Walters will require a blood transfusion from her cousin Bruce Banner after being shot, which ultimately transforms her into "a similar green monster." The logline specifically mentions that she will eventually go on to join The Avengers.
Marvel is currently searching for an actress of open ethnicity in the 26 to 34-year old age range with strong comedic chops.
Mark Ruffalo has played coy in the past when asked if he was set to return as Banner for the show, but if the character does appear on screen, we assume the Avengers: Endgame actor will play the role."
I think it was kinda obvious that the blood transfusion would be how her origins go. I don't think there's really any other way to do it when it comes to She-Hulk.
(Also I know she's around the age of 39, but I still think they should cast Stephanie Beatriz for Jennifer Walters).
