Night Terror

"It's not one big dragon, it's tons of little ones!"

- Hiccup discovering the Night Terror flock.

The Night Terror is a small Stoker Class dragon that flies in overwhelmingly large packs which appears in the series Dragons: Race to the Edge.

Egg
Night Terror eggs are small and dark in color in "Rise of Berk". They have a wavy, thick, dark green fin surrounding the egg and it resembles the shape of the Night Terror's Tail. They have patterns similar to its fin on its shell. The purpose of this fin is unknown. Alpha Terrors' eggs are white in color. In School of Dragons, however, they are completely white, with rough scales.

Hatchling to Adult
Night Terrors are small dragons that are slightly larger than the Smothering Smokebreaths and the Terrible Terrors. Each individual Night Terror is black in color, except for the alpha. When they group together, especially at night, they appear to be all black in color and they form the shape of any large dragon. They have small teeth and a rounded tongue. They have two small horn-like ledges on top of their nose. They also appear to have a short tail with four, short, thin spikes on the tail.

The alpha is white and slightly larger than the others. It appears as an eye of the large dragon shape in the swarm of themselves or other dragons.

Titan Wing
Titan winged Night Terrors have grown larger and their main body remains black while the horns and the end of their tail become blue. The ledges on top of their snout is longer and more wrinkly. Blue horn-like structures grow out of their neck and head and their claws grow sharper. Also, their whole tail is longer and appears to be sharper.

Flying Together
Night Terrors are able to fly closely together in order to form the shapes of larger, more terrifying dragons for protection. This behavior resembles that of European starling or certain schools of fish, who fly or swim together in order to appear larger so as to scare off predators. Also, each swarm has an alpha. The alpha is able to control its fellow dragons and instruct them to form certain formations and often takes the spot of the dragon's eyes.

Their formations don't only show remarkable space awareness, but also incredible coordination as larger forms are able to do certain actions like flap their wings, move their body part etc., reflecting the Night Terrors' ability to move collectively.They have been shown forming a Night Fury, Fireworm Queen and a larger Night Terror.

Speed
Night Terrors are incredibly fast and strong fliers, especially when they are together in a swarm. This makes sense as moving in swarms, especially that of the shape of a dragon, which as a streamlined body, reduces air resistance and allows these dragons that form the body instead of the head, to travel faster.

Dragon Controlling
The alpha Night Terror can control smaller Night Terrors, organizing them into a formidable flock that appears to be a larger dragon when posed with the threat of oncoming predators. Without the Alpha, these Terrors are susceptible to other dragons like Changewings as they cannot function as a team.

Fire Breathing
A single Night Terror breathes an admittedly tiny fire blast. However, when a swarm of these dragons fires, the little shots can turn into a massive fire ball.

Intelligence
They are able to form the shape of other dragons, making themselves look bigger. They even figured out their own way to get rid of the Fireworms by forming themselves into the shape of a Fireworm Queen. It is possible they had never seen a Fireworm Queen before, but they had the idea to make themselves look like Ia large Fireworm, hoping they would be followed by the smaller Fireworms.

Behavior and Personality
Because Night Terrors have a bit of the personality of bats, they fly as a colony and are nocturnal. They also have a great respect for their Alpha.

Albino Night Terrors could become very possessive as seen with Fishlegs Ingerman. These albino Night Terrors have shown to be cave dwellers as they lived in the dark cave to avoid daylight and come out at dark.

Weakness
Night Terrors are incredibly weak on their own, as they have very small fire blasts, not much strength and are very scatty and jumpy without their leader, so by capturing the Alpha Night Terror you could probably take down the whole flock.

The Night Terror's disguise as a larger dragon would easily fail during the day, as a predator saw the white of the Alpha and the outlines of all of the other Night Terrors in the daylight. This is why Night Terrors are nocturnal.

Albino Night Terrors are afraid of the sunlight as they are cave dwellers. They were also unable to withstand clanging sounds until they got used to them.

Season 1
In When Darkness Falls, the gang found a new island to call their own outpost. That night, Tuffnut wakes up in the middle of the night to see a gigantic dragon. They decide to chase down this mysterious dragon and eventually, find out that the dragon is not a single dragon but multiple dragons, tiny ones forming the shape of a larger one. They capture the leader and named it Smidvarg and the species Night Terrors. That night, Changewings attack the Night Terrors. They quickly release Smidvarg so that he can command the Terrors to form a larger dragon to scare off the Changewings. Eventually, the riders decide to share their island with the Terrors.

In Gone Gustav Gone, Gustav was harassing Smidvarg and the gang. When Hiccup settled them down and sent Gustav off, Smidvarg roared angrily at him.

In Reign of Fireworms, The Terrors saved the island from migrating Fireworms burning it to ash. The Terrors form the shape of the Fireworm Queen to draw the Fireworms away onto a barren island, where they have nothing to burn.

Season 2
In Team Astrid, Astrid and Hiccup catches the twins playing with Night Terrors even though they were supposed to be on duty. Tuffnut taught them to fetch sticks, which Hiccup failed to understand how that skill served in battle. In the Edge to Disaster part II, Ryker shot down a Night Terror on guard with a poisoned arrow.

Season 3
In Follow the Leader, Fishlegs found a colony of Albino Night Terrors in a cave at the Edge. They were living in isolation, making use of the supplies left behind by an ancient civilization. Thus, they were very scared of light. They treated Fishlegs as their leader and refused to let him leave. However, one Night Terror, Darkvarg, treated Fishlegs with respect and allowed him to leave by stopping the other Terrors. Though it seems likely that many years ago before it was discovered by Fishlegs this cave belonged to someone else that was the original leader of the Albino Night Terrors as they found ancient language and sword with writing on it as Fishlegs was unable to read it.

Dragons: Rise of Berk
Night Terrors became available in Rise of Berk promptly after the episode aired. The individuals Smidvard, Darkvarg, Nightwatch and Hotshot also became available and were given unique personalities.

School of Dragons
The Night Terror also appeared in School of Dragons.

Trivia

 * Originally, Tuffnut wanted to call the dragons "Smidvarg and the Gang".
 * Their ability to fly in a large group is similar to Scarers.

 * According to Rise of Berk, Night Terrors are extremely elusive. This may be because of their skittish tendencies and the fact that many a Viking could be scared off by them while thinking they were a larger dragon.
 * The Night Terror is the third black dragon to be seen in the franchise after the Night Fury and the Sword Stealer.
 * Night Terrors are very similar to Speed Stingers.
 * Both hunt in packs.

 * They are both nocturnal.
 * Both can move extremely quick.
 * Both don't know what to do without the leader.
