There is a secret supernatural history to the world of Kittiwake Comics. Though, just as in our world, the majority of women burned as witches, staked as vampires and exorcised as demons were just unfortunate mentally ill or counter cultural individuals, some of them actually were supernaturally gifted and many of their supposed “deaths” were just minor inconveniences.
With Kittiwake Girl’s example of how the odd and the powerful could finally come into the open and use their Powers without fear of persecution Supernaturals soon got in on the Superlady act.
The damage resisting gift that Supernaturals have as a default is far greater than anything possessed even by Aliens with their odd physiology. However they still must be wary as Weapons blessed by the Creator (in whatever guise He is followed) can overcome this ability.
As the bodies of Supernaturals are forever bound to their souls true death is depressingly permanent for them and they do their level best to avoid it.
