Adam is the first man. He is as old as the Earth. He claims he's the original dick and that every human comes from him. He thinks he's better than everyone else except for archangels and seraphim angel, which are his bosses. He think he had never made a mistake in his life.   
After becoming an angel, he became the commander of his private military force known as Exorcists which killed demons/souls in hell. Loves killing demons. He is cruel, sadistic, sexist.
