Beast = Anti-Christ = Azazel = Abaddon = Apollyon
The Beast is from the bottomless pit and the bottomless pit is opened at the fifth trumpet.
Revelation KJV Chapter 9:1-12 Fifth Trumpet
1: And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the Bottomless Pit.
2: And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
3: And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power.
The bottomless pit is also near the Euphrates River in Iraq
Revelation KJV Chapter 9:13-16 Sixth Trumpet 4 angels
13: And the sixth angel sounded, and I heard a voice from the four horns of the golden altar which is before God,
14: Saying to the sixth angel which had the trumpet, Loose the four angels which are bound in the great river Euphrates.
15: And the four angels were loosed, which were prepared for an hour, and a day, and a month, and a year, for to slay the third part of men.
16: And the number of the army of the horsemen were two hundred thousand thousand: and I heard the number of them.
Some of Satan's fallen angels did unspeakable acts with human women to try to corrupt the Seed of Woman in an attempt at thwarting the messianic prophecy of Genesis 3:15. These angels and other demons who were initially free are now permanently confined in Tartarus (a section of Sheol or Hades). Other demons are temporarily confined to the Abyss (another section of Sheol or Hades) before they are released to roam free again. The bottomless pit!
1 Then said the Most High, the Holy and Great One spake, and sent Uriel to the son of Lamech,
2 And said to him: 'Go to Noah and tell him in my name "Hide thyself!" and reveal to him the end that is approaching: that the whole earth will be destroyed, and a deluge is about to come upon the whole earth, and will destroy all that is on it.
3 And now instruct him that he may escape and his seed may be preserved for all the generations of the world.'
4 And again the Lord said to Raphael: 'Bind Azazel hand and foot, and cast him into the darkness: and make an opening in the desert, which is in Dudael, and cast him therein.
5 And place upon him rough and jagged rocks, and cover him with darkness, and let him abide there for ever, and cover his face that he may
6,7 not see light. And on the day of the great judgement he shall be cast into the fire. . . .
8 . . . the whole earth has been corrupted through the works that were taught by Azazel: to him ascribe all sin.
(The Apocrypha and Pseudepigrapha of the Old Testament enoch 10, R.H. Charles)
Leviticus 16
10. But the goat, on which the lot fell for Azazel, shall be set alive before Jehovah, to make atonement for him, to send him away for Azazel into the wilderness.

Other interesting notes
"When Saddam Hussein's mother encountered difficulties in her pregnancy and doctors recommended an abortion, she traveled to Baghdad for medical care and stayed with friends in the Jewish community. Eventually, a healthy boy was delivered, whom she named Saddam, or "destroyer"," for the pain the pregnancy had caused."
The prophecy states that the leader over the army that would cause the sun and the air to be darkened by smoke would be called "the destroyer."
A king over them whose name is the destroyer
Revelation 9:11 "And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon."
The word Abaddon is Hebrew for "the destroyer." The word Apollyon is Greek for "the destroyer." Two Bible translations actually translate this passage "the destroyer" (The Emphasized New Testament by Rotherham and The Twentieth Century New Testament).
