The "beast" and "false prophet" are ROLES that the "dragon" will play at the end.
Davy, the beast (king) and the false prophet are two humans, two Jews. They will be cast alive into the lake of fire at Jesus's return. Diffently, at that time, Satan will be cast into the bottomless pit.
Satan, during his final time, times, half time after being cast down to earth - will indwell the statue image of the beast king, placed on the temple mount. And thus be worshiped, unknowingly, by anyone who worships the image.
When Jesus returns to stand on the Mt of Olives directly across from the temple mount, He will stare down the statue image, that speaks and breathes, turning it to ashes. Exposing Satan there on the temple mount for everyone present to see him. And the angel in Revelation 20:1-3 descends with a chain, binds Satan, and he is cast into the bottomless pit.
Where I get the information about the statue image turned to ashes is from Ezekiel 28:16-19 which is about Satan's end as being a terror.
16 By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
17 Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness:
I will cast thee to the ground, I will lay thee before kings, that they may behold thee.
18 Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick;
therefore will I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee.
19 All they that know thee among the people shall be astonished at thee:
thou shalt be a terror, and never shalt thou be any more.
Here is a graphic I made of that day.
