Undead dragons are the remains of fallen dragons that have risen and/or been withered through necromancy or other means and originated from the different dragonflights. They can appear usually as reanimated bones. Some are controlled by the Scourge under the Lich King, while others are raised or controlled by other powerful individuals.
- Emberwyrms, raised by necromancy from red wyrms of the red dragonflight.
- Fel dragons, raised by fel magic, presumably from dragons of any dragonflight.
- Frost wyrms, raised by necromancy from wyrms of various dragonflight.
- Magmawyrms, raised by necromancy from black wyrms of the black dragonflight.
