Lizard King
From Tardis Wiki, the free Doctor Who reference
The Lizard Kings were the Silurian-like inhabitants of Mondas, along side the Human-like Mondasians and the Mondasian Sea Devils, although it could be that they too were called Lizard Kings.
History
The Cybermen sent out a cybership to the Dark Continent to search for the lost Lizard Kings, finding statues of them only. (DWM: The Cybermen)
