Lucifer

Lucifer is the Emperor of Hell and a Fallen Angel. Before his defeat by Michael, his twin brother, he was Chief of the Seraphim and the Closest to God.
Initially, it was unknown what Lucifer's looked like, since the most of his body was always covered in his wings' feathers. He has six wings and seems to wear shoes with rather high heels.
He resembles a lot to his son, Camio.
