When interviewed by a catholic researcher as to why he had killed them he said "Because only the Catholics may prosper".He has claimed that he was "summoned" thousands of years ago by the a cult that tried to make him fight the church but he saw the "flaws" in the cult and killed them all and joined the first crusade where he claims he found "His purpose". Sir Joseph was found in Jerusalem Israel causing havoc.He is thought to have mind affecting ability's as when he was found in Jerusalem there were other people joining him and causing more havoc and he can sense what people believe. If Satan is brought up to Joseph he will become distressed and jumpy.
It is known that he is not human under his Armour as he has openly stated but has always refused to take off his Armour however when the foundation tried to use thermal images to see who was under the Armour there was no heat signature given off and it is unknown if he is cold blooded or non organic.If anyone damages his Armour he can either go into a berserk or complain about how expensive Armour is and fine whoever damaged his Armour. He is aloud to go into public every Sunday as he will go to church.When he goes out to church he often goes shopping for food on the way back and goes to get his Armour repaired at a location he refuses to share with personnel. He never kills on Sundays as it is a day of worship however if he does not go to church on Sunday the next day he will kill everything he can see in an attempt to escape witch has caused the death of 15 MTF squads.
