Hades is the Greek god of the Underworld, as well as the name of the Underworld itself. Despite many modern portrayals, in Ancient Greek mythology, Hades was not represented as evil. Later Christians used the name as being synonymous with the Devil, which seems to be the inspiration for the forms that the monsters with this name take.
