Grold
From Tardis Wiki, the free Doctor Who reference
The Grold were a fluorosilicone life form.
Biology
Grold were more like stone than flesh and required massively high temperatures to function. They were eighteen feet tall humanoids with six-fingered hands and a humped back. They had what looked like a football-sized ruby in their forehead, which functioned as both an eye and a brain. They could shoot energy beams from it, and use it to hypnotise humans.
