Unknown Dragons (Franchise)

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, How to Train Your Dragon 2 and How to Train Your Dragon: The Hidden World 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 discovered many new species of dragons. He has recorded the location of these dragons on 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 1

 * This dragon is based on early concept arts of Cloudjumper.

Dragon 2

 * This dragon is based on early concept arts of the Deadly Nadder.

Dragon 3

 * This dragon's name was revealed by a piece of concept art seen in the Making of How to Train Your Dragon 2.

Dragon 5

 * This dragon may be the Songwing, the dragon that inspired the Death Song.

Unnamed dragon species from the Films
Apart from the Bewilderbeast, Stormcutter, Rumblehorn, Hotburple, Scuttleclaw, Seashocker, Hobblegrunt, Snafflefang, Raincutter, Thunderclaw, Windstriker, Thornridge, Snifflehunch, Shovelhelm, Threadtail, Windgnasher, Tusslefang, Bristleback, Hornsneaker and Fogcutter have been seen in How to Train Your Dragon 2. These dragons were created using a modular system to mix and match preset body parts onto 2 basic models. the Tusslefang, the Bristleback, the Snafflefang, the Thunderclaw, the Shovelhelm, the Windgnasher and the Snifflehunch are all created from the same body. the Hornsneaker, the Fogcutter, the Thornridge, the Hobblegrunt, the Raincutter, the Windstriker and the Threadtail are all created from the same body.

There is a dragon species name that surfaced as leaked info for How to Train Your Dragon 2. This name was copyrighted prior to the release of the movie: Cloudcutter.

The same unnamed dragons in How to Train Your Dragon 2 also appear in How to Train Your Dragon: The Hidden World.

Tusslefang (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.

Dragon 5
Hazy images of a dragon with the body type of the Snifflehunch appear in the background of How to Train Your Dragon 2. It has a large, rounded sail on its back and a tail ending in a fork. One fan theory suggests it is an animation error for a Snifflehunch. However, it has a forked tail and all these dragons are designed with interchanging parts such as a sail back and forked tail. Another theory suggests it is a Snifflehunch with the ability to expand and hide a sail, though this is not mentioned anywhere officially, or on other media such as Dragons: Rise of Berk, where the Snifflehunch appears. This dragon slightly resembles a Mudraker.

Dragon 6
In How to Train Your Dragon: The Hidden World, transparent and glowing dragon eggs are seen in the foreground of the Hidden World of dragons. Only the developing dragons are seen inside, and there is no indication what species they might be. Certain body parts of the dragons in the eggs indicate they might be Light Furies.

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.

This dragon was later found to be yet another piece of Red Death concept art.

Dragon 3
This dragon has a very long snake-like body. It appears to be brown or white in color and has a very long snout, similar to the Shivertooth. Its body and face appear to be covered in spikes. It has only two legs with four finger on each, two little wings and a very long tail.

This dragon appears on various concept arts for How to Train Your Dragon 2.

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.

Dragon Racers: The Dragon Berry Dash
Two varieties of dragon are seen as enemies in the game. They race against Hiccup and Toothless in the main game and carry power ups in certain minigames.

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.

Tormentipede
According to Richard Hamilton, the graphic novel The Fire Tides was to include a new dragon species named the 'Tormentipede'. Unfortunately the graphic novel project was scrapped due to delays with previous graphic novels, and before an artist was assigned to it. Therefore no concept artwork or concrete description exists for this dragon other than the name.

Three-Eyed Dragon
In The Dragon Sheep Chronicles, "The Secret Sheep Society", the Sheep of Berk express their distress at the increasing number of dragons surrounding them. In the images of a group of hapless sheep surrounded by various types of dragons, there are two dragons that appear with three eyes, three striped horns on their face, and Zippleback-like rounded spines running down their backs. At least two rear legs are seen in the image, but it is unclear if they have forelegs or not. They do have a pair of small wings.

Unidentified 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". Another skull is worn as a head cover by Skuld the Sorceress in "The Endless Night". Several skulls were seen on The Reaper, with two unknown skulls 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. Another 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.
