This page contains dragon species that are, as of yet, unidentified. These dragons come from many different sources, from concept art to dragons that aren't named in the films. These dragons are all listed below.

Concept Art Dragons

Many concept art dragons that were made for How to Train Your Dragon and How to Train Your Dragon 2 can't be connected to any of the dragons that appear in the movie. These dragons have never been seen outside of these pieces of concept art (so far).

Dragons from Hiccup's map

During his travels, Hiccup has found many dragons. He has recorded the location of these dragons in his map. In the poster that comes with Guide to the Dragons a lot of new dragon species can be found. Some of these dragons were previously seen in concept art for the movies.

Dragon from Fishlegs cards

Fishlegs is a big fan of dragons and as such he has crafted a set of cards that he carries with him all the time. These cards show information about all the dragon species he knows about. In How to Train Your Dragon 2 an unknown dragon species can be seen during a brief moment when Fishlegs is reading his cards. According to the symbol on the back of the card, this dragon is a Mystery Class dragon, but nothing else is known about it. Although it looks similar to a Timberjack and its name could be read as Timberjack too.

Yet to be named dragon species

Apart from the Bewilderbeast, Stormcutter, Rumblehorn, Hotburple, Scuttleclaw, Seashocker, Hobblegrunt, Snafflefang, Raincutter, Thunderclaw, Windstriker, Thornridge, Snifflehunch, Shovelhelm, Threadtail, and the Windgnasher, 4 other unnamed dragon species have been seen in How to Train Your Dragon 2.

This name was copyrighted prior to the release of the movie:

  • Cloudcutter

Dragon 1

  • A bipedal version of Dragon 1 also appears to be the basis for the HTTYD Toy set "Toothless & Hiccup Vs. Armored Dragon Figures". Visit Amazon to view a purple version and a light green version.

From The Serpent's Heir

The back of this dragon was seen in The Serpent's Heir. It's a member of the Tidal Class, but nothing else is known about it as of now.

From Book of Dragons

Three unknown dragons are seen during a scene in the short film Book of Dragons.

Dragon 1

This dragon is very large and is entirely grey. It has several bumps on its back that look somewhat like plant buds. It seems to have two frills on either side of its head. This dragon has many eyes. Some are on its head, while others are on its two frills. This dragon's horns appear to have leaves on them. Its body seems to have a fur-like covering. Its neck and tail seem to have some kind of vine hanging down from them. This dragon has enormous wings. Its wings appear to be old and haggard, as several rips can be seen all along the wing's length.

Dragon 2

This dragon is mostly bluish in color and has a rotund body. It has two, long, thin, blue wings. This dragon has a wide mouth filled with many teeth. The teeth go all around this dragon's mouth. This dragon has what appears to be moss growing up its back. This moss grows from its neck to the start of its tail. This dragon also seems to have little plants growing off of the moss. This dragon has four, short legs and a long tail.

Dragon 3

This dragon is very long. It appears to be brown or white in color and has a very long snout. Its body and face appear to be covered in spikes. It has two legs with four finger on each, two little wings and a very long tail.


School of Dragons

The face of an unknown dragon appears as one of the targets in the minigame Fireball Frenzy. The dragon's face is dark in color. It has yellow eyes and slitted pupils. Its mouth is lined with sharp teeth.

Dragons: Rise of Berk

A toy of a bipedal green dragon with yellow belly is an item that can be found with Toothless in explorations during Snoggletog.


Hiccup's Toy

Hiccup's toy doesn't match the appearance of any known dragon species. It looks like a Night Fury, but with Deadly Nadder horns and frill spikes.

Unknown Dragon Skulls

Several unknown dragon skulls are seen in the series. One is placed on the bow of all of the Outcast Tribe's ships. It appears similar to the head of a Moldruffle and may even be of the same species. Strangely, a different skull is seen on the bow of the Outcast ships in Dangers of the Deep and three more are seen on other Outcast ships in The Legend of Ragnarok. Several skulls were seen on The Reaper, with three being inside dragon cages and three more being seen outside the cages. Another skull is briefly seen on the outside of Viggo Grimborn's tent. The final skull is seen inside Viggo's tent. It has the facial bumps and frill of a Windgnasher but has massive horns, a trait which the Windgnasher lacks. Two more unknown dragon skulls are seen on Drago Bludvist's ship, The Conqueror, in How to Train Your Dragon 2. Another unknown dragon skull is seen on a hideout decoration in School of Dragons, while another is seen as an object for the reader to search for in Look And Find: How to Train Your Dragon. In the game Dragons: Rise of Berk, there are skulls of unknown dragons decorating some dragons' roosts.

Look And Find: How to Train Your Dragon

In the first picture of this children's "Look and Find" book, the dragons are attacking Berk and stealing Sheep. All the dragons are recognizable as one Night Fury, Hideous Zipplebacks, Monstrous Nightmares, Gronckles, and Deadly Nadders, except one. This one has the color of Nadders in the picture, but has orange stripes and a single row of spines on the back of its head. Its head is shaped differently and appears to have front legs. 

Another unknown dragon appears later in the book. It is seen as part of the drawings in Hiccup's workshop. It is depicted wearing a saddle. It is unknown what kind of dragon it is, but it does share parts of the Night Fury and the Deadly Nadder.
