2Right, I don't know which vengeance angel Apollyon ranks among the fallen angels. An Old Testament name that appears in Old Testament battles with Jehovah. The official language in this section overwhelmingly supports the evil spirits behind evil governments. Describing these locusts is the Old Testament language of political economy. But at the same time, Satan typically maintains his armies. The apocalypse is decidedly against totalitarian governments, which cease to exist. There are topics in Revelation where some critically comparing these conflicting images with modern war tactics is nonsense. For an angel is mightier than a modern army. 

 If you look at Old Testament images of angels, they serve as spirits to gentle saints. Angels described in the Old Testament destroyed entire cities. Our prayers, which David reliably conveyed to us, are a message of vengeance. Angels to subdue our formidable enemies.Angels can astound people's minds, not just physically destroy them. Angels create significant confusion in wicked men. Angels can gradually destroy a man with his thoughts. All of these images when Christ came to earth in Old Testament word forms. Words used throughout the Psalms.
