Most people don't know exactly who or what made Isidora Amunet into the hefty life-sucking cat creature she is today, as no one alive today remembers who or what she used to be before she became said life-sucking cat creature. Isidora herself is rather suspiciously forgetful, though she does allude to ancient Egypt and their common stance of cat worship as being part of her origin story (a common ruse used to fool her prey, we'll get to that later).
The few that have managed to find tidbits about her throughout history find that she may have been some sort of handmaiden (a foreigner, and a pretty one at that) who had the primary duty of pampering cats... a job she enjoyed well enough, even if royal cats were even snootier than the normal type. Her curiosity got the better of her one day, though, as if she herself were a cat... investigation into some odd noises in the palace one day caused her to stumble upon an assassination attempt, which her very presence foiled. Of course, the assassin managed to kill her before he left, but at least the pharaoh survived, right!
Well, she wasn't royalty, and she was a foreigner to boot, so they mostly just dumped her body in the Nile... but luckily for her, Bastet had taken a shine to her thanks to her love for the kitties, and she was rather quickly poofed back onto the mortal plane as an odd demigoddess of sorts, bearing a set of enchanted (or is it cursed?) claw gauntlets and boots to show everyone she was pretty legit and not too happy.
She'd been granted a rather unique ability, as well... she was able to suck the life force out of anyone she touched, draining them away rapidly while flooding their minds with intense pleasure and leaving them dessicated husks of flesh and bone. She got revenge on her murderer, and taught the pharaoh himself a lesson about respect, before fading off into the desert with cats trailing along behind her. For years she shadowed Egypt, smothering out pockets of corruption wherever she could find them~
'course, she could be making all of that up, and she could just be a graverobber who got her paws on some cursed gauntlets and is using them to eat you.
That was quite a while ago though, and seeing as the Egyptian pantheon's MIA, she's more or less a freelancer... and by freelancer, we mean she skips around devouring whoever or whatever she wants for no reason other than her own amusement and pleasure.
She's a pretty big girl, and while she's capable of 'normal' vores (oral, hair, tail, anal, etc) her primary method of eating is by sucking out her prey's life force via any sort of contact, which she occasionally enhances with sexual stimulation of some sort. In short, she basically squeezes the life out of you, crushing you into nutrients with her incredible softness.
