Official Description 

Fiercely territorial, Singetails don't just breathe fire—they send it blasting out of their jaws, gills and tails. First discovered by Spitelout when he colonized Storehouse Island, the elusive Singetails prefer to scare away their enemies with long-range attacks, like hurling fireballs from their tails. However, Singetails also pose a danger in close-quarters combat by shunting jets of flame from their gills lining their exposed underbellies. No dragon or rider can ever get the drop on a Singetail due to its articulated eyes—they swivel to the sides and back of its head and give the Singetail a 360-degree lay of the land. Since it can look at two directions at once, the Singetail can act as its own tailgunner. It's best not to get in a Singetail's way. These territorial Dragons can blast fire out of their jaws, gills, and tails! Sneaking up on a Singetail is hard enough, but finding its weak spot during battle is nearly impossible! 

Physical Appearance 

In Dragons: Rise of Berk, the eggs look more like a flaming bush, with frill-like fins lining across its length and a color scheme of red, orange, and yellow. 

Hatchling to Adult 

Singetails have a wide, flat body and a long tail. They have four wings, like a Thunderdrum, but with the bigger pair being set lower on its back. They have a spiky face with chameleon-like eyes that allow it to see in multiple directions, as well as several big, sharp spikes along their backs and tails. They have eight extremities (four wings and four legs), two more than most other dragons and with the rearmost pair seemingly a modified pair of extra hind limbs unlike the Stormcutter, which has all four forelimbs as wings. 

In the series, they are red without stripes, unlike the ones in Rise of Berk. 

Abilities Endurance and Stamina 

Singetails can fly for long distances without showing any signs of exhaustion, while also carrying the extra weights of humans and metal chains. They can receive continuously beating from a whip without losing any stamina. One individual was able to survive being buried under many trees, showing no injuries. Singetails can take powerful shots from other dragons, such as a Night Fury and a Rumblehorn, without receiving too much damage. When in the air, they can recover easily after being shot and barely unbalance for a few seconds. 

Speed and Agility 

Singetails can fly at great speeds, as they can keep up easily with other fast dragons, such as Night Furies and Deadly Nadders. Singetails are very agile dragons, able to dodge attacks from their foes. Thanks to their double set of wings, Singetails can do tight turns and easily maneuver through tight places. 

Eye Movement

The Singetails' eyes can move independently one from the other, which allows the dragons to see two different directions simultaneously. Their eyes can also swivel to the back and sides of their heads, giving them a 360-degree view which resembles that of a chameleon.

Social Nature

Singetails will call others of their kind by spreading fire all over their current locations. 

Singetails can shoot fire from not only their mouths but from their tails and bellies as well. Their stomach fire is achieved due to the gills that line their underbellies. They often use this as a defense from those attacking underneath, as is demonstrated by Krogan's Singetail. The fire that the Singetail produces is scarlet and can be used to mark their territories or as a signal to call for reinforcements from its own species. Singetails can also use the fire from their bellies to temporarily boost their speed like a rocket. The heat from the fire of some Singetail individuals, such as Sear, can be felt from 10 feet away and others, such as Infernier, can immediately light on fire any nearby torch, hearth, or furnace with their flames. 

Strength and Combat

Singetails are a very strong species of dragon, as they can carry humans and metal chains on their back with little to no effort at all. This is most likely due to their bulk and large frame.

Singetails are fearsome adversaries in battle, for they are more than capable of taking on a Night Fury amongst other species with little struggle. They are competent fighters, capable of sparring with multiple dragons at once, and even overpowering them. Even if they are losing a battle, they can summon other Singetails with a distress signal of fire.

Sagefruit Immunity 

As shown by the Mother Singetail, Singetails are unaffected by the calming effects of sagefruit due to their carnivorous diet, and will spit it out if consumed. 

Weaknesses Altitude 

Spitelout Jorgenson discovered that Singetails cannot fly at high altitudes, not even Titan Wings. This serves as a route of escape if being pursued by one. The reason for this is likely because the higher up birds go, the denser the air becomes and requires more physical effort to keep flapping their wings, so the Singetails with their large body and double the number of wings of most dragons and the positioning of their wings may make it harder for them to fly. 

Fog 

Singetails are shown to be very reluctant to fly into a heavy fog in "The Wings of War, Part 1". This is presumably because they cannot see where they are going, even though other dragons seem to be able to sense their direction. However, this weakness does not seem to affect all Singetails, as Krogan's Singetail had no problem flying through the fog. 

Neck 

When their necks are pinched in a certain spot, Singetails fall unconscious/asleep. This was shown in "Living on the Edge" when Krogan subdues an Ambered Singetail. 

In ancient times, the Singetail was one of the most feared dragons. However, there was one dragon whose powerful blasts could neutralize the Singetail's fire. The Singetail's only predator: the Skrill.  

In "Triple Cross", Viggo uses a Skrill to counter the Dragon Flyers' Singetails, knowing that the Skrill is the Singetails' natural predator and the Skrill's electric blast can neutralize its fire. 

Flower Vapor 

As mentioned in Stoick's description in Dragons: Titan Uprising, a Singetail can be put into an inebriated slumber by letting it breathe in a pleasantly perfumed vapor created by slowly cooking fragrant wildflowers with its own body fire. While in this sleep state, Singetails are completely harmless, with Vikings being able to approach, touch, or even sleep with their head resting on the dragon with no danger of being attacked. 

Behaviour and Personality

Singetails are fiercely territorial and will fight any dragon or human that they consider a threat. They are aggressive towards any dragons that are not their kind.

When they are not busy fighting or marking their territory, Singetails can be very lazy. They eat and sleep all day if they are not disturbed.

Singetails are exclusively carnivorous, their favorite food being the Ice-tailed Pike. They also prefer to live on non-volcanic islands.
