There’s a syncretic folk religion that is catching on in Mexico and America. It’s a cult devoted to "Santa Muerte" who is depicted like a Grim Reaper goddess wielding a scythe.
Popularity has shot up because followers believe she’s done miracles. Her mythology isn’t set, but some suppose she is some kind of fallen archangel. The followers are predominately women in places that have become disillusioned with the institutionalized Catholic church.
Wikipedia lists her under folk saints – popular fictional saints that certain Catholics believe in. They are basically mini-gods, not unlike ancestral Gods or Japanese Kami.
Naturally the Catholic church has tried to stamp it out in Mexico, and some vandals recently smashed a statue to her in a Texas cementary. And yet with the violence in Mexico her grisly following has shot up by several million, and immigrants have begun to bring her to America. So if you see a plastic statue to a grim reaper in the future, it might actually be a deity rather than cheap Halloween decor.
I asked /christ/ about it, and they just called her a demon. All foreign goddesses are demons for Catholics/Protestants unless you happen to believe in them, in which case they are saints.
On a related note I see a lot of death gods in anime and wikipedia hints at the historical reason: Catholic influence!
