Michael: Prince of the Heavenly Host. Tall, muscular, broad-shouldered, dark hair, big blue eyes... Looks and acts pretty much like Daniel Nastoya. XD
Rafael: Archangel of Healing. Shorter, slimmer, long reddish-brown hair, dreamy grey eyes. Gets scared really easily, but he's the supersweetest guy you'll ever meet, and will go to Hell and back to help someone.
Lucifer: Lord of Hell, once Archangel of Light. Tall as his twin brother Michael, but more slender. Long, dark hair, golden, slitted eyes, tends to wear a lot of leather. A playful and perverted demon-prince who can do really weird things with his tongue.
