Films: The Asphyx (1972)
Location: Civilized area
Height/Weight: That of a housecat.
Summary: The Grim Reaper can't possibly get ALL the souls that die in a day. What the spirits of the recently deceased need is an escort each into the next life. Thus, enter the Asphyx.
History: Supposedly a being of Greek myth, the Asphyx is the spirit that guides the recently dead into the afterlife. It appears almost right before one's demise, so it is possible to see it. Naturally, some idiots get the idea that if they were to capture their own Asphyx, they would be immortal. Also naturally, it all goes wrong in a number of ways.
Notable Kills: It spectates every kill. If we're being generous, there's been an Asphyx for all the previous movie deaths.
Final Fate: An Asphyx is eventually captured, but the man after it realizes that living forever has more negatives than positives (figure that one out for yourself). However, considering how much death he caused to achieve that, he decides that his eternal life is a divine punishment he deserves.
Powers/Abilities: Completely indestructible.
Weakness: Can be captured via a device involving phosphorus and water.
Scariness Factor: 4-This is the thing that guides your spirit. This shrieking, hideous monstrosity. Maybe people wouldn't fear death that much if their escorts weren't so unsettling.
Trivia: -This film is also known as "Spirit of the Dead" and "The Horror of Death".
-The Asphyx is almost completely based off the Banshee, an Irish spirit that also shrieks up a storm when someone is about to die.
