Nurse Asclepius was the presumed Greek God of Medicine and Healing mentioned in the story "A Special Creature: The Pink Merdog," set in the Trauma Center continuum, which was dealt with as a mission by Agents July Flame and Library.
Because Asclepius was found within a dream of the Mary Sue creature, he was recruited due to his preference to remain unharmed and not be stuck there. Once at HQ, he joined Medical, which has made him happier than he'd ever been before. He remains grateful to July and Library.
Asclepius is blond and may have some powers due to being a godlike entity: he was able to repair JF's concussion while she was on fire after July tried to kill her.
