Powers of Good & Evil

Good does not have any powers. They may get some has time goes by and by their number of successes. Evil, however, was given powers by Satan. During each mission, the demons go to Earth and take the guise of something in the plotline. Example, Wild West: Gunfighter or Saloon Girl. They are real people then. Angels are never real and can only be touched by other Angels or Demons. Angels can not drink, eat, etc on Earth. They walk through walls and not go through doors.
