Aptronyms: Meet Mrs. Fussbudget and Father Sin
Although it's a bit heavy handed, you can give fictional characters personality by using aptronyms: names that suit the owner's traits or profession. A fallen priest may be Father Sin or a persnickety woman may be Mrs. Fussbudget.
For laughs, publications sometimes print names of real people whose names are strangely suited to their professions, such as a dentist named Dr. Driller or a builder named Mr. Nail.
