So, in Rev. 20:1, we read of "an angel", "αγγελον", which is N-ASM (Noun - Accusative - Singular - Masculine) and has no definite article (no "the")
Rev 20:1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.

This is a messenger sent from JEHOVAH, the Ancient of days (Dan. 7:9,13,22 KJB), from "heaven" "down" towards the earth (implied) and paralleled in Rev. 9:1, see chart on past #5 -
Revelation 20:1-15 & the 1,000 years (aka Millennium) Bible Study and is bearing "the key of the bottomless pit", and "a great chain in his hand". At this point only this "an angel" is being discussed.
This "angel" is no ordinary personage of Heaven, and is not even among the created heavenly hosts, for it is none other than the Son of the Father (the 'angel (messenger) of the covenant'; Mal. 3:1b) holding these things, for notice in 1 Thes. 4:16 (paralleled in Jhn. 5:25,28-29 KJB, and in Job 14:15 KJB and context thereof):
1Th_4:16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
1Th 4:16 οτι αυτος ο κυριος εν κελευσματι εν φωνη αρχαγγελου και εν σαλπιγγι θεου καταβησεται απ ουρανου και οι νεκροι εν χριστω αναστησονται πρωτον
John 5:25 KJB - Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live.
John 5:28 KJB - Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice,
John 5:29 KJB - And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
The Son of the Father is called an "angel" in other places in the Revelation, such as in Rev. 10:1,5,8-10:
Rev 10:1 And I saw another mighty angel come down from heaven, clothed with a cloud: and a rainbow was upon his head, and his face was as it were the sun, and his feet as pillars of fire:
Rev 10:5 And the angel which I saw stand upon the sea and upon the earth lifted up his hand to heaven,
Rev 10:8 And the voice which I heard from heaven spake unto me again, and said, Go and take the little book which is open in the hand of the angel which standeth upon the sea and upon the earth.
Rev 10:9 And I went unto the angel, and said unto him, Give me the little book. And he said unto me, Take it, and eat it up; and it shall make thy belly bitter, but it shall be in thy mouth sweet as honey.
Rev 10:10 And I took the little book out of the angel's hand, and ate it up; and it was in my mouth sweet as honey: and as soon as I had eaten it, my belly was bitter.
The very symbolic description of this "angel" (messenger) for the Father, matches several other OT places, and even some NT places, for the description of the Son of the Father. For more details, see

When the other symbols ("key", "bottomless pit", "great chain", &c., such as the connecting resurrections of the righteous (saved) and finally impentitent (lost) mentioned in Rev. 20:4-6) are studied in connection with this "an angel" it will be more clear still.
Yet even still, throughout scripture, the Son has been sent down to the earth by the Father on numerous occasions, even beginning in Genesis, and continuing throughout. A few brief (non-exhaustive) mentions:
Gen. 3:8, "the voice of the LORD God", walking in the Garden of earthly Eden.
Gen. 11:5, "and the LORD came down"
Gen. 17:1, "the LORD appeared to Abraham"
Gen. 18:1,21, "the LORD appeared unto [Abraham]", "I will go down now"
Gen. 19:24, "the LORD rained upon Sodom and Gomorrah" (while standing on the earth, having left off talking with Abraham)
Exo. 3:2,4,6 "the angel (messenger) of the LORD (JEHOVAH the Father)", "... the LORD ... God ... out of the midst of the bush ...", "Moreover he said, I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob. And Moses hid his face; for he was afraid to look upon God."
Exo. 13:21, "And the LORD went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night:"
Exo. 14:21, "Exo_14:24 And it came to pass, that in the morning watch the LORD looked unto the host of the Egyptians through the pillar of fire and of the cloud, and troubled the host of the Egyptians,"
Exo. 23:20-21,23 "I (the Father) send an Angel (the messenger of the Father, the Son), before thee, to keep thee in the way ...", "... my (the Father's) name is in him (the Son).", "mine (the Father's) Angel (messenger, representative, the Son)
&c.
Jhn. 1:11, "He came unto his own ..." (1st Advent)
NT (throughout) - Jesus continually refers to the Father sending the Son down to the earth with the good news.
In Rev. He comes down in the 2nd, and yea, even 3rd Advents.
However, skeptics will always say:
Exo 4:1 And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice: for they will say, The LORD hath not appeared unto thee.
Even in Malachi 3:1, the Son is directly called the 'angel (messenger) of the covenant':
Mal 3:1 KJB - Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple, even the messenger (Heb. H4397 "ומלאך", "ûmal'akh'", "angel"; Grk. G32, "ἄγγελος", "angelos") of the covenant, whom ye delight in: behold, he shall come, saith the LORD of hosts.
Mal 3:1 HOT - הנני שׁלח מלאכי ופנה־דרך לפני ופתאם יבוא אל־היכלו האדון אשׁר־אתם מבקשׁים ומלאך הברית אשׁר־אתם חפצים הנה־בא אמר יהוה צבאות׃

Mal 3:1 Origen's Hexapla Greek - ἰδοὺ ἐγὼ ἐξαποστέλλω τὸν ἄγγελόν μου, καὶ ἐπιβλέψεται ὁδὸν πρὸ προσώπου μου, καὶ ἐξαίφνης ἥξει εἰς τὸν ναὸν ἑαυτοῦ κύριος, ὃν ὑμεῖς ζητεῖτε, καὶ ὁ ἄγγελος τῆς διαθήκης, ὃν ὑμεῖς θέλετε· ἰδοὺ ἔρχεται, λέγει κύριος παντοκράτωρ.
Jesus is often connected with "keys" as well. See Isa. 22:22; Rev. 3:7-8, and Mat. 16:19; & Mat. 11:52; & Rev. 1:18; see also Mar. 7:34; Luk. 3:21; Rev. 8:1, &c. More detail shall be studied, when coming to the phrase "key of the bottomless pit".
