I'm not sure why, but in the animated series of the remake she's drawn completely flat chested, even though her civilian identity as Adora WAS drawn with breasts. I'm not sure if that was done deliberately or just as an accident...? o_O
A quick study of the showrunner, Noelle Stevenson, and it's easy for me to see that she is a narcissistic amateur. She's got no experience under her belt, but wants to reshape the characters to fit her own specific tastes and agenda, and has admitted to inserting her tabletop character to the show, which may as well be tantamount to a self-insert. Mind you, she doesn't even have experience in tabletop either, as she only started around the same time as she started working on this show. Add how nearly all the promotional material until the week or so before release was focused almost exclusively on her, and not the show, and it's easy to get that Stevenson is just stroking her own ego and has no interest in making a good show.
Narcissism and incompetence are very frequent bedfellows with each other.
