Taureau

Taureau was a hostile, beret-wearing Minotaur-like creature. The Fourth Doctor and Romana II encountered Taureau in the catacombs of Paris around the turn of the millennium. Taureau worked with a human-looking mime who lured people into the catacombs through portals and then into the centre of the maze where Taureau lived. They would eat raw anyone who could not answer Taureau's riddle. The Doctor stole Taureau's key and he and Romana exited the trap through another portal, which atomized Taureau.

When the Fifth Doctor later found himself back in the Parisian catacombs, he recalled meeting Taureau during his last venture into them. (AUDIO: The Gates of Hell)
