Inspirations - (Supernatural) Reaper

As I love all these mystery and horror stuff, the American TV series "Supernatural" is one of my favorite.

In the drama, they have Demons, Lucifer, Angels, Ghosts, Vampires, Four Horsemen of the Apocalypse, Leviathans and Shapeshifters...etc, all these monsters in the myth, they even named the character and told the story after different religions. Such as Lillith which was Lucifer's second-in-command.

The reaper in it's true form

One of the character that interested me is the grim reaper.
"Reapers are servants of Death. They assist in maintaining the Natural Order, and are completely neutral, not aligned with Heaven or Hell nor Purgatory."(reference)
Their job is to escorting souls to where they belong.

The reaper turns into a girl named Tessa

Reapers(in Supernatural) tried to convince the spirits to let go and come with them but they couldn't tell where they were going.
Reapers were able to change the appearances to different forms.

If I were the reaper and wanted to monitor you, I would have turn into something that you could trust, such as a person, a pet...etc.
