Nemean Lion (Greek) - An enormous monstrous lion with a skin so tough that no weapon can penetrate it. Its thick black manes are covered in arrows and other weapons. Nemean Lions are also known as Golden Lions or Dire Lions, the best way to kill them is to drown them or to strangle them, but with very great strength this creature can only be strangled by more powerful creatures.
