During the Second Great War, a Winged Nightmare aided in the defense of Skygeirr Platform against the attack by the Zerg Swarm. It was unsuccessful in stopping the attack on the labs.[1]
Game Unit[]
The Winged Nightmare appears in the mission "Hand of Darkness" in Heart of the Swarm, but only on the casual and normal difficulties. It uses the same model as the regular wraith unit.[1]
Unlike other members of the Royal Guard, the descriptor for the Winged Nightmare does not say "Part of Arcturus Mengsk's Elite Guard."
Data in the Galaxy Map Editor exists for the Winged Nightmare to have the Tomahawk Power Cell and Displacement Field upgrades, but they are absent in the final game.
