Karl Echo is a Nazi Were-Sloth.  He is married to Sophie Casterwill Echo and has two daughters.  He is a scholar in Historical Jesus studies and is secretly gathering research to prove that Jesus had two penises.  He claims he belongs to a group of super-powered were-beasts called The Deadly Sins whose mission is to gather the Seven Unusual Relics of Jesus for an unknown reason.  Sophie believes it’s all an outcropping of Karl’s damaged and immature imagination.
