Archangel Michael is the only angel called 'archangel' in the Bible. Some faiths also refer to him as 'Saint Michael'. In the Book of Revelation Michael is the leader of God's angels against Satan's forces, where during the war in heaven he defeats Satan. He is often represented as an angelic warrior, fully armed with helmet, sword, and shield. He may be standing over a serpent, a dragon, or the defeated figure of Satan, whom he sometimes pierces with a lance.
