Well, just being silly for a moment...
I'm pretty sure Death is not a cute Goth girl. Did Death look that way in WWI? In ancient Greece? In Cro-Magnon times?
In theory, if in the 1990's, teenage girls were able to psychically connect with Death and mimic her appearance and start the Goth fashion craze, why didn't this happen centuries earlier?
Not to mention how strange Death would appear to an alien race of insectoid-octopii.
