Marvel: Diamond Skin

Hollow
Hollow has red diamond-hard skin and extended razor-sharp claws on their fingers, toes, and hair follicles that are sharp enough to shred the skin of anyone touching her. Because of the density of the skin, it also has a highly reduced capacity for physical injury, as well as a mind that is resistant to psychic intrusion. Her skin absorbs light, making her appear to be in constant shadow.
