First Appearance: Fright of Passage
Last Appearance: Fright of Passage

The Flightmare is a Mystery Class Dragon that appears in Dragons: Defenders of Berk. It appears in the episode Fright of Passage.


The Flightmare is a medium-sized dragon that has a very ghost-like appearance. Its body is covered in small spots that almost resembles the night sky. It slightly resembles a mix between a Skrill, a Night Fury and a Fireworm, with glowing scales.


From what has been seen, the Flightmare is a very aggressive and territorial dragon, being very protective of it's territory and food sources. Seeing how Flightmares are build for speed and defense, they usually avoid fights with bigger and stronger dragons. Flightmares have been shown to be quite determined, as the Flightmare in Fright of Passage kept chasing his opponents, and was willing to search food over long distances.


The Flightmare's body glows by eating algae that shines along with the Northern Lights. It can strike with a mist that paralyzes its prey to give itself enough time to return and finish it. Flightmares have shown to be quite fast and agile, as the specimen in Fright of Passage was able to catch up with Toothless with ease.

Defenders of Berk

The Flightmare first appeared in Fright of Passage, terrorizing Berk every ten years. Last time, Astrid's uncle, Fearless Finn Hofferson, faced the dragon and seemed to be frozen by fear, shaming her family's name. Astrid and Hiccup set out to find the Flightmare, where Astrid tried to fight it, but was frozen by the dragon's mist. They learned that victims of the dragon were not frozen by fear, but paralyzed. They soon discovered a stream of glowing algae that gives the Flightmare its glow, as well as other dragons (as discovered by Toothless). Realizing that the Flightmare only attacked Berk because it thought the Vikings were threatening its food supply, Hiccup, Astrid, and Fishlegs created a new channel for the algae to flow into the sea, and the Flightmare left Berk. Hiccup explained to the village what they learned about the dragon and that Finn Hofferson truly was fearless, restoring honor to Astrid's family.

Notable Flightmares

Wild Flightmare (see Fright of Passage)


  • In order for the Flightmare to kill its prey with its mist, it needs to spray its prey for about 5-6 seconds to let its victim freeze to death when the temperature is about -20 degrees.
  • The Flightmare's wings are slightly transparent.
  • The Flightmare is the only known dragon that appears once every 10 years.
  • The Dragon Tracker Part 3 special feature on the DreamWorks Dragons:Defenders of Berk Part 1 DVD (released 3/25/2014) reveals that the Flightmare is a Strike Class Dragon. [1] Oddly enough, the new book Guide to the dragons reveals the Flightmare to be a Mystery Class dragon.
  • The Flightmare's design is similar to that of the Skrill, resembling that of Pelican eels.
  • It is the only dragon that glows other than the Fireworm, and both glow via eating something.
  • The Flightmare's mist can paralyze people and animals for about 1-2 minutes, which is pretty short, but it gives enough time for the Flightmare to get an easy kill.
  • The Flightmare is an omnivore, because it eats glowing algae which is filled with hundreds of tiny fish.
  • When the Flightmares was first seen in the Defenders of Berk trailer, many fans thought it was a Skrill.
  • The Flightmare is the only known dragon that doesn't have a forked tongue.
