Izzy

There is a lot to Izzy that she doesn't know herself. The most momentous event of her life was when she died.
The issue is she doesn't remember that.
She doesn't remember much of anything...

She just came to one day, in a body that couldn't sustain her soul. For years she walked the world in a body that slowly decomposed around her. Driven half insane from living in a corpse Izzy managed a small miracle. She managed to implant herself with small, incredibly complicated machinery.

Now Izzy could pass for a living creature, so long as no one cut her open to see the turgid blood or neon-green fluids pumping around her body, rejuvenating her cells on a molecular level. Having lived the afterlife in such a rough fashion has left an indelible mark on Izzy.

Still, she is bizarrely full of life and meets the world with a roguish grin.
