Minotaur

The Minotaur was a creature from Greek mythology. It was said to have the head of a bull and the body of a man.

The Second Doctor and Zoe Heriot encountered the Minotaur in the Land of Fiction. It vanished when they denied its existence. (DW: The Mind Robber)

The Third Doctor learned that the Minotaur was real during a trip to Atlantis. The creature was formerly a member of Dalios's court, a great athlete who desired the strength of a bull and a long life in which to use it. Kronos granted him his wish, and the creature was made guardian of the Kronos Crystal until the Doctor defeated it. (DW: The Time Monster)

The Greek hero Theseus was renowned for fighting the Minotaur. The Fourth Doctor claimed to have given Theseus the ball of string he used to find his way around the labyrinth in which the Minotaur resided. (DW: The Creature from the Pit)


 * It is unknown if this is the same Minotaur from Atlantis or a different one.

The Fourth Doctor and Romana encountered a hostile, beret-wearing Minotaur named 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 center 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 caused the Minotaur's sanctum to self-destruct. (IDW: The Forgotten)

Extraterrestrial life forms which resembled Minotaurs include the Nimon, a related species and the Tauride. (DW: The Horns of Nimon, The God Complex, DWBIT: Minor Trouble)
