Seran wrapped spy
I was looking for Public Domain characters and found this. And I still don’t know if she’s Public Domain or not!
If the "Public Domain Superheroes" wiki is accurate, then apparently she is, so you have your answer! https://pdsh.fandom.com/wiki/Black_Angel
Also it sucks to be a spy(?) and forced to have to wear black saran wrap after your bra's been stolen. ):
