Interesting question. In particular for some of those demons that have split personalities…can’t think of any off the top of my head, but I know there are some crazy demons out there.
:-k I think it would be sort of up to the demon on the names changed, like a father naming his children. Of course if the demon isn’t that bright he might not think to do it and some sort of auto designation would have to occur. Perhaps like in DID (Disociative Identity Disorder-AK multiple personalities) where each personality has a name, Sybil, Vickie, Peggy so maybe Sybil Prime, Sybil-Vickie, Sybil-Peggy Although one should hope for better demon names. Sybil is good, but a demon named Peggy? That’s about as ridiculous as a demon named “Tom” These new demons, they have no respect for the old naming conventions like my old friend Astaroth Nesferith Giger Prometheon or Buford Terrence Malachai Ezekiel…those were names…and easy to split up when their personalities finally broke down after a couple millenia of torture…
