Apollyon : Angel of the Abyss

He shall lead the locust-like swarm of demons that will be released in the End Times. In appearance the locusts are like unto horses arrayed for battle; on their heads what looked like crowns of gold; their faces like human faces, their hair like women's hair, and their teeth like lions' teeth; They shall have scales like iron breastplates, and the noise of their wings shall be like the noise of many chariots with horses rushing into battle. They have tails like scorpions, and stings, and their power of hurting men for five months lies in their tails. They have as king over them the angel of the bottomless pit;

       His name is Apollyon.
