Giese is a ghoul living in Los. He is one of only a few ghouls who is not hostile to humans, unlike many others from Blake's fanatical cult. In his past, he was a robot engineer for the Secret Vault, but when a conflict arose between the Vault inhabitants, he became one of those who was left outside the Vault. He is able to fashion weapons from pieces of junk and knows the location of Secret Vault. The Initiate could find a total of four pieces of junk to bring to him. The best weapon he could make from junk is a super sledge.
