Armed Police Gravekeeper

I am an armed policeman. During a mission, I was seriously injured. After I died in the hospital, I was summoned to another space by a bald man, who gave me a new life and a heaven-defying talent. I can change the shape of my body at will. For example, my hands can turn into keys and my feet can turn into alloys weighing several tons. But my mission is to rob tombs!
