Susini of the Wasting Wall was a Necrotist.
She went to the Mexican village of Coyoacan on 2 November 1941, which was the annual Day of the Dead holiday. She brought along the Torajenn to help in her latest art project. They would strip the flesh from their victims to cover their own skeletal bodies, then bring her the bones so she could build a great skeletal tower.
The Eighth Doctor used the ultrasonic projector she had brought with her to destroy the Torajenn. When she tried to kill the Doctor, Diego Rivera pushed her into the vortex she was using to create the tower. It stripped her flesh and killed her, then made her part of her own artwork.
