The Winged Nightmare is an unused unit from Galaxy Map Editor files for StarCraft II: Heart of the Swarm. The Winged Nightmare is a powered-up wraith, with higher HP and power. The files indicate it was to be part of the Elite Guard fought on Korhal in the final mission, but they are unimplemented in the final product. Unlike the other members of the Elite Guard, the Winged Nightmare uses the same model as its base unit.
