Minotaur

In Greek mythology, the Minotaur was a creature with the head of a bull on the body of a man, or "part man and part bull". He dwelt at the center of the Cretan Labyrinth, which was an elaborate maze designed by the architect Daedalus and his son Icarus, on the command of King Minos of Crete.

The Minotaur was eventually killed by the Athenian hero Theseus.
