Once Upon a Time (She Had All the Riches in the World)
Angelique Mors. Her name wasn't always Cruella de Vil, and when she was a little girl (before she discovered her love of fashion and furs) they called her Angelique Mors. Then she became a business star, a prodigy in her own right. And when the tabloids named her Cruella de Vil in mocking honour of her disregard for the lives of the animals she used as her fur supply, it just stuck. And so, maybe it wasn't perfect, but she became Cruella de Vil.
And then she hired darling Anita, with her brilliant ideas and impeccable fashion sense, and she decided that she wanted a daughter just like her. And Anita designed what would've been the greatest coat she'd have ever owned, and Anita was a star employee, because of spots. But Anita married Roger, and their dogs had infernal puppies, which she so desperately needed, but they couldn't seem to see that, so she took her own measures.
And she failed.
And then they locked her up on this infernal island, and she hated them, she hated Belle, and what wouldn't she give to skin that beast and his son alive. And then she managed to get herself knocked up, and Maleficent refused to do away with the foetus because Maleficent believed that life started at conception, and Maleficent couldn't bring herself to kill like any other supervillain. And how pathetic was that?
Carlos was a brat from the moment he was born. Too scared and weak and no sense of fashion, which was really all she ever asked for, so he slept in the cupboard because he was expendable, but her furs, her darling furs that she managed to salvage had to be kept safe.
When she saw that Jafar was lending out his spawn, she realised that she could actually find a use for the pathetic child with no fashion sense, so he started working. And he worked hard. He cleaned and cooked and when she discovered that he was pretty handy with a knife she sent him out to do the killing for her, and he did so well, so she would send him with the furs to the Evil Queen's daughter, and she could sew like no other. And so what if the killing had a negative effect on her son? She needed those furs.
When her son- King Carlos the Deceitful- summoned her to his throne, she knew it was over, because Jafar had been the last one to leave, and she hadn't seen him since. And in front of his throne, there was an operating table filled with all sorts of tiny tools Angelique didn't know existed. And she was told to strip and to lie down, and then the pain started. Her son, her baby, the one who had garnered the furs for her best coats on the Isle, was using those skills she had taught him once upon a time, and making due on those threats, and skinning her alive. Angelique died young and weak and poor, the exact opposite of what everyone expected.
And if her son wore a human skin coat after she died, the one skin she never managed to collect, who cared? He was a king, and she was nothing.
(And Angelique was poor and her son had everything she wanted.)
