A Harpy was a type of ravenous monster from Greek mythology that would attack people in order to steal their food, though they were not above kidnapping people as well - they were sometimes regarded as embodiments of the destructive nature of the wind and were considered spirits rather than true flesh and blood. Harpies were originally depicted as winged human females but over time became more associated with their current form as ugly bird-women hybrids, in most myths they retain their savage behavior regardless of form.
