Diatryma is a huge, flightless, meat-eating bird; a Gastornis. She has a scare on it's leg and so she cannot hunt for her self. Thats why she made an unsteady alliance with Adapis, leader of Tree runners that they bring her food, while in return, she will protect Tree runners clan. Adapis tried to sacrifice Icaron's colony to the bird but Dusk realizes this and saves the whole colony, leaving the bird hungry. Diatryma appeared in Darkwing.
