Dr. Alfred Prunesquallor: The castle's resident physician. He is an eccentric individual with a high-pitched laugh and a grandiose wit which he uses on the castle's less intelligent inhabitants. Despite his acid tongue, he is an extremely kind and caring man who also is greatly fond of Fuchsia and Titus. (Several times, Dr. Prunesquallor's first name is given as "Bernard", but this inconsistency is considered an error on Peake's part.) Although he appears at first to be foppish and weak, the doctor later shows himself to be both intelligent and courageous, and he plays an important role in defeating Steerpike.
