Hollow

When asked by the scientists, whose lab Hollow had repeatedly broken into in order to steal cages full of mice in order to feed the writhing knot of mambas that served as its head, why it did not simply buy mice from exotic pet supply stores, the being reportedly did not reply, but one of the snakes struck a nearby lab technician, delivering a deadly bite that killed her within minutes.

It is theorised that the latex suit the being wears is actually a part of its body and helps keep its blood (tests have proven it to be human blood, type AB+) contained within its skin.
