The Ship of Theseus is a philosophical question, which questioning is the object stays the same if all of the original parts replaced? My thoughts about this dilemma of Vox I placed in the comment section below. I thought a lot about self-identity as fanons. At first, I have a fanon about Vox as a biomechanical creature, who can change any of his parts. Digging deeper, I think that he appreciate yourself in mortal life, but got a new form in the Hell, very different from the humans and his self.He can change his body parts, head too, when it breaks. I like to think that as a human before, it is hard to him to accept yourself and associate with something different, not usual and new, that became more and more different from every replacement from his original form.
