Michael

The only holy angel other than Gabriel named in the Bible, and the only one called “archangel.”

Scriptural evidence indicates that the name Michael applied to God’s Son before he left heaven to become Jesus Christ and also after his return. Michael is the only one said to be “the archangel,” meaning “chief angel,” or “principal angel.” The term occurs in the Bible only in the singular. This seems to imply that there is but one whom God has designated chief, or head, of the angelic host, if the designation “archangel” applied, not to Jesus Christ, but to other angels, then the reference to “an archangel’s voice” would not be appropriate. In that case it would be describing a voice of lesser authority than that of the Son of God.

The book of Revelation (12:7, 10, 12) specifically mentions Michael in connection with the establishment of God’s Kingdom and links this event with trouble for the earth: “And war broke out in heaven: Michael and his angels battled with the dragon, and the dragon and its angels battled. And I heard a loud voice in heaven say: ‘Now have come to pass the salvation and the power and the kingdom of our God and the authority of his Christ, because the accuser of our brothers has been hurled down. . . On this account be glad, you heavens and you who reside in them! Woe for the earth and for the sea.’”

He is also Lucifer's eldest brother.
