Fishlegs: "The Smothering Smokebreaths build their nest out of metallic objects."
Tuffnut: "That doesn't sound too cozy. Or does it?"
Fishlegs: "It's not supposed to be. They do it to defend against attacks by bigger dragons."[src]

The Smothering Smokebreath is a small Mystery Class dragon that first appeared in the Dragons: Riders of Berk episode, Breakneck Bog .

Official Description

Smothering Smokebreaths are elusive creatures that prefer to stay hidden.
While not inherently aggressive, Smokebreaths will attack Vikings that intrude on their territory. Rather than breathe fire, these dragons instead exhale plumes of thick black smoke. Being communal creatures, these individual smoke clouds often combine into what appears to be a large fog bank. Many a Viking ship has been scuttled due to these dragon-made fogbanks, which suits the Smokebreaths just fine, as they scavenge the wreckage for bits of metal to use in building their nests.
The Smothering Smokebreaths' greatest hidden ability is actually their supernatural reputation. Entire Viking villages have cleared out at the sight of their unique black smoke, misattributing the haze to ghosts or fjord phantoms. With the village streets and homes empty, the Smothering Smokebreathes then have free reign to pillage for every bit of metal they can find.
Wondering where you left your favorite axe? It might have been snatched by this sneaky Mystery Class metal hoarder (hidden in a cloud of smoke).
Where there's smoke in battle, there might just be a fire-breathing Smothering Smokebreath nearby!

The Smothering Smokebreath likes to stay hidden. It pumps out smoke from its skin to create a thick cloak of fog.

Originally, the Smothering Smokebreath took on a more ghostly appearance, featuring a flatter skull, darker skins, and casts a larger ghostly, translucent, shadow-like smoke over themselves, as seen in early concept art. Artists also depicted them with more frills and spines, and the 'shadows' emitted a stream of smoke encircled by rings.

Physical Appearance

The egg of a Smothering Smokebreath is dark brown with several, large and small, brown bumps all over it, with a crack in the middle of the shell. There appears to be a strange purple color underneath the egg. The egg in Dragons: Rise of Berk is more spherical than the ones in School of Dragons which appear to be oval.

Hatchling to Adult

The Smothering Smokebreath is a bit larger than a Terrible Terror, with a flatter body, but it is entirely gray. The head and mouth are almost as big as its body, and it has no discernible neck. It has short, stubby legs and a wingspan equivalent to over twice its body length (though in its debut its body was longer than its wingspan). Its tail is long, thin, and very spiky.

Titan Wing

Titan Wing Smothering Smokebreaths have a shiny green and grey coat. Their snout, wing edges, and belly is green, while the rest of their body is grey. These titans have blue stripes on their wings, similar to those of a tiger. The spines on their back, neck, and tail are larger, longer and sharper too. Overall, this dragon has increased in size.



Smothering Smokebreaths can create a veil of smoke to hide from enemies or victims. They excrete this dense fog from their skins. In addition, their fire also tends to create a great deal of subsiding smoke as it is released.

Because of this ability, it was thought to be a kind of "Fog Monster" and became legendary, to the point that, although the Book of Dragons had information about it, Fishlegs believed it was just a myth. According to Valka, scratching a Smokebreath under the chin will cause it to produce large amounts of smoke.

The smoke of some Smothering Smokebreath individuals, such as Flutter-Fog, is said to smell like spring flowers, although all those who have tried to smell the smoke have ended up gasping for breath afterwards.


Although they usually breathe smoke, Smokebreaths can breathe a very hot fire, since it is capable of melting metal in a matter of moments. A large swarm may appear as a strange smoke cloud. The Book of Dragons in Wild Skies says the smoke is pumped out of their skin.


Smokebreath packs have the habit of collecting treasures and "shiny things" to merge them together to create their nests, in order to defend themselves from other dragons. They often go to extremes to collect treasure, as shown when

they all formed a cloud of smoke and chased the riders for their metal. When flying in groups, Smothering Smokebreaths make a noise similar to a bat sound to communicate with the other dragons.

Another of their characteristics described in the Book of Dragons is that they are very territorial. A group of them live in caves on an island called Breakneck Bog (which, in a group of five islands resembling a hand, is the thumb).

Speed and Agility

Smothering Smokebreaths are fast flyers, for they are able to easily evade and outmaneuver humans as well as other dragons.


Smothering Smokebreaths hunt in complete stealth. Hidden by the smoke, they surround their prey and close until it cannot see anything, so they attack.

A single Smokebreath by itself is relative of little consequence, but an entire swarm is powerful enough to tear apart a fleet of Berserker ships or bring the Isle of Berk to the brink of defeat by stripping it of nearly all the metal available.

Strength and Combat

Smothering Smokebreaths are much stronger than Terrible Terrors, as one was able to pull Hiccup into the air and carry him at great speed to catch up to its swarm. Entire swarms can lift whole ships filled with cargo out of the ocean and relocate them to great heights, provided the target is close enough to their home.


Pack Dependency

Their strength is through their numbers. One Smokebreath alone isn't enough to keep themselves concealed. They are also extremely vulnerable when they are by themselves.

Behavior and Personality

Tumblr mu44iijBDp1rfphnoo1 500.gif

Smokebreaths are social creatures. They live in large packs and work together as a team. Together they create nests out of materials, preferably metals, which they weld together with their flame. When traveling together they fly in groups and use their smoke to keep themselves concealed from potential predators. They are elusive and prefer to stay hidden. They are not aggressive, but they are territorial and will defend their homes from any threat, large or small, including Vikings. They won't hesitate to plunder the precious metals from Viking ships and nearby villages. Their method of concealment has given them an infamy, often referred to as a "Fog Monster", "Fjord Phantoms" and even ghosts.

Despite their pack behavior, some Smothering Smokebreath individuals, such as Smogger, are capable of surviving on their own.


Create a fancy nest, made of the best scrap metal you can find. Whether the Smokebreaths decide to move in or take it apart is up to them, though.

Comparative Statistics


How to Train Your Dragon

The Smothering Smokebreath makes its very first appearance in the movie, being visible for a slick moment when Hiccup is reading through the Dragon Manual.

Book of Dragons

A group of Smothering Smokebreaths can be seen in Book of Dragons short, once Gobber opens the book. (They are in the upper right corner just behind the big, gray, unknown dragon, which could be another Red Death).

Dragons: Riders of Berk

In the episode "Breakneck Bog", everybody believed that Breakneck Bog to be haunted by some kind of "Fog Monster". The Riders found an unconscious Trader Johann on a wooden plank. He says he was attacked by the "Fog Monster". When they investigate, they discover that Johann's merchant ship is on top of a tree. After the ship drops, the "Fog Monster" chases the dragons and their Riders. They are revealed to be Smothering Smokebreaths after the dragons used their wings to clear the smoke.

A little later they see the dragons welding metal objects along with their fire to build their nest and Hiccup is also present in the cave. Fishlegs says they do it to protect themselves from larger dragons. Using a bright gold necklace Snotlout had found at the ship to distract the Smokebreaths, Hiccup escapes and recovers the box that was on Johann's ship. The dragons and Riders chased them and threw all their metal objects that the Smokebreaths have taken and returned. A Smokebreath attacked Hiccup's Prosthetic Leg but Fishlegs attacked and turned back, but is still afraid of him. The Riders and dragons returned safely to Berk.

Dragons: Defenders of Berk

In "Smoke Gets in Your Eyes", Johann then bought a scrap metal pile from a Berserker, which he then sells to Gobber. Unknown to anyone, there was a Smokebreath nest in it, and soon the dragons took all the metal in Berk. Shortly after the village was almost completely stripped of its metal, including weapons, Dagur and his fleet were making their way to Berk. Fortunately, Hiccup and the other Riders were able to attract Smokebreaths to the vessels, where they took the metal, causing them to sink. After the metal was recovered, the Smokebreaths were later taken to Breakneck Bog, courtesy of Johann's ship.

Dragons: Race to the Edge

Season 2

Main article: Dustbrawler

When Bandit stole Snotlout's axe in "Snotlout Gets the Axe" and placed it on its back, Snotlout decided to get it back with some help from the Smokebreaths. A group of them that lived on a nearby island (possibly Breakneck Bog) followed Hiccup, Astrid and Snotlout to Iron Isle and tore the armor off of an Armorwing. When the situation got out of control, the Riders lured the Smokebreaths away with one giant melded piece of metal.

Season 6

A group of Smothering Smokebreaths was summoned by the Berserker Bewilderbeast during the final fight in "King of Dragons, Part 2". They can be seen lifting a Dragon Flyer from his Singetail before throwing him to the ocean.


DreamWorks Dragons: Wild Skies

The Smokebreath is one of the Mystery Class dragons in Wild Skies, along with the Changewing. They are also the only Wild Skies dragon to be displayed in groups. They can be found in the Monstrous Nightmare's lair on Lava-Lout Island when offered mutton or crabs. Training this dragon unlocks the 'Pickpocket' achievement.


Dragons: Rise of Berk

The Smothering Smokebreath and its Titan Wing form appeared in Dragons: Rise of Berk. Later the Exotic Smothering Smokebreath followed. Exclusive individuals were also released: Rattling Smokebreath, Dustbrawler, Gritpicker, Smogger, and Flutter-Fog.

School of Dragons

The Smokebreath also became available in this game, and there is a Viking jacket inspired by its design. They also appear in the quest "Honey, I Stung Snotlout" in which Valka uses one to smoke a beehive for honey.


  • Asterisk-Transparent.png The official measurements given by DreamWorks Animation do not appear to be realistic when considering the relative sizes the viewer sees within the TV series. Based on the Model Sheet for the Smothering Smokebreath along side other known dragons in the series such as Toothless, this dragon should be 10 feet (3.05 meters) long, 1 feet 7 inches (0.5 meters) tall, and have a Wingspan of 9 feet 3 inches (2.82 meters).
  • The Smothering Smokebreath is similar to both a bat and a magpie, because a bat likes to live in caves and in large groups, and magpies like to collect shiny objects to build their nest.
  • The original image of the old Wild Skies Smokebreath looks much like a Monstrous Nightmare, but when the dragon was released the game's image in the book was changed to coincide with the dragon. It is possible that this was concept art, but the designers decided to change it because it was too similar to the Monstrous Nightmare.
  • Smothering Smokebreaths are similar to the Terrible Terror, as they travel in groups, are smaller than most dragons, as well as bringing objects together. This is seen when two Smokebreaths try to snatch Tuffnut.
  • While a whole group of them appeared in both of their episodes, the Smothering Smokebreath is one of the few known species not to have any differences in color.
    • In Wild Skies, however, they are black in color instead of smoky gray.
  • These dragons may have been the reason for the fog around Dragon Island, but this was not confirmed.
  • Even though the Smothering Smokebreath is seen breathing smoke, the Dragon Tracker Part 2 claims that the smoke comes from its skin.
  • In Rise of Berk, the Smokebreath baby is slightly larger than the adult version.
  • It is possible that Smothering Smokebreaths used to gather raw ore to make their nests. With the arrival of Vikings to the archipelago 300 years earlier, they may have then adapted their behavior to also scavenge Viking metal as it would be easier to collect.
  • According to Dragonpedia, the Smothering Smokebreath's smoke contains extremely hot air, which makes the smoke itself extremely hot.
  • The concept art of the Smothering Smokebreath and their shadows looks very similar to the Night Terror flocks.
  • Smothering Smokebreaths and Armorwings appear to be natural enemies, as they fight over and steal scrap metal.
