Creature (The Monsters of Coal Hill School)

Humanoid creatures created a replica of Coal Hill School on another planet. Clara Oswald taught English to them in what they hoped would preparatory learning preceding an invasion of Earth. French teacher Jeff Delobel was also inside the replica. The Twelfth Doctor came to the planet looking for Clara. He told the creatures stories of an adventurer who defeated would-be conquerors. The Time Lord asked them to guess of whom he spoke, with the realisation that it was the Doctor causing them to abandon their scheme. (COMIC: The Monsters of Coal Hill School)
