Trivia: Panning around Diana's apartment, the camera briefly lingers on a photo of her with an elderly lady, with no elaboration of its significance. But look closely and you'll realise the woman in the photo is Etta from the first movie, again played by Lucy Davis, just made up to look 67 years older.
Trivia: At one point during the movie Wonder Woman uses her lasso to move around by riding the lightning. This is a reference to the Metallica album "Ride the lightning" which came out in 1984. (02:04:00)
Trivia: Original Wonder Woman actress Lynda Carter has a cameo at the end of the movie.
Trivia: The golden armour was seen in the Kingdom Come comic book.
Answer: This was not explained in WW84, so any answer would be speculation. It is rumored that Lynda Carter, who played Asteria, may appear in Wonder Woman 3, which will hopefully explain her backstory. She is probably similar to Diana, who also chose to live among regular humans, secretly using her powers for good.
