Krargs, also known as Kraags, (PROSE: Shada) were creatures made of crystallised coal.
Biology[]
They were large, strong, semi-intelligent lumbering creatures with vivid red eyes. They were able to withstand high amounts of energy and could burn with a touch. When more Krargs were needed, they were created in large vats of heavy green gases that solidified coal over a skeleton. They had space carriers with smaller ships. (WC: Shada)
History[]
When the Tenth Doctor first glimpsed a Pyrovile in Pompeii in 79 AD, he thought it might be a Krarg. (PROSE: The Fires of Pompeii)
Delegates representing the Krargs attended the Armageddon Convention at Laputa in 1609. (PROSE: The Empire of Glass)
Krargs were used by Skagra as his own personal army. (WC: Shada) The Fourth Doctor saw a Krarg imprisoned cryogenically on Shada, noting it was strange how a lava creature could be frozen. (PROSE: Doctor Who and the Krikkitmen)
A Krarg was exhibited in the Space Museum when the Vashta Nerada invaded. (WC: Hall of Monsters)
