Arkham City: The Order of the World (2021-) #6

Dr. Joy has reunited with her missing patients. Now all the survivors of Arkham Asylum's destruction are together again under one very, very nice and normal roof. But they are not alone in this strange reflection of their old home. For there is a specter with them, one of flame, flesh, and righteous fury-the angel Azrael, and he is very, very angry.
