Revelation 9:7-11

7And the locusts looked like horses prepared for battle, with something like crowns of gold on their heads; and their faces were like the faces of men. 8They had hair like that of women, and teeth like those of lions. 9They also had breastplates like breastplates of iron, and the sound of their wings was like the roar of many horses and chariots rushing into battle. 10They had tails with stingers like scorpions, which had the power to injure people for five months. 11They were ruled by a king, the angel of the Abyss. His name in Hebrew is Abaddon,1 and in Greek it is Apollyon.2
