Rakshassa
From Tardis Wiki, the free Doctor Who reference
The rakshassi (plural of rakshassa) were the servitors of the being which claimed to be Azathoth. She created them when she mind controlled other sentient beings. After being under her influence for a time, they would transform from their original shape into rakshassi. They were named after a type of demon from Hindu mythology.
They were red armoured crustaceans with leathery wings, and a coiled tail with a spiked club of flesh on the end. (PROSE: All-Consuming Fire)
