In Revelation chapter 12, the angel Michael leads the heavenly battle against the dragon. Revelation 12:7 describes Michael and his angels fighting the dragon and its angels in heaven.
The chapter presents the dragon as a cosmic enemy associated with Satan. After the conflict, the dragon is defeated and cast down from heaven, along with the angels who follow it. The passage identifies the dragon with “the ancient serpent,” the Devil, and Satan.
Michael is not a major recurring figure throughout Revelation. In fact, chapter 12 is the only place in the book where he is explicitly named. His role here matches the broader Jewish and Christian tradition of Michael as a powerful defender and commander among the angels.
The chapter also includes the woman, her child, and the dragon, making it one of Revelation’s most symbolically dense visions. Interpretations differ over the identities of those figures, but the angel leading the battle is named directly: Michael.
