Speed Stinger

The Speed Stinger is a Sharp Class dragon that appeared in Defenders of Berk. They are flightless and hunt in packs and have a leader, the Lead Stinger. It appeared in the episode Frozen, and also appeared in School of Dragons, and reappeared quite frequently in Race to the Edge.

Official Description
"The Velociraptors of the dragon world, Speed Stingers are fast, aggressive and intelligent. They use coordinated attacks, moving in packs dozens at a time, all led by the Lead Speed Stinger. Speed Stingers have wings, but they are small and undeveloped, so this species is essentially flightless. Confined to land, they rely on ice bridges and glaciers to move from place to place in search of food. They are the fastest dragon on land. While other dragons such as Nadders and Night Furies, can outfly them, no one can outrun a Speed Stinger. A nocturnal dragon, this Speed Stinger expend so much energy after dark that they must sleep throughout the day. Typically, they seek shelter in caves or tunnels to avoid predators while sleeping. The Lead Speed Stinger is identifiable by its red wings and red stripes along his body (in contrast to the uniform green of a regular Speed Stinger). The regular Speed Stinger will follow the Leader anywhere, without hesitation. The Speed Stinger's chief weapon is its poisonous barbed tail. Even a single sting can render any human or dragon completely paralyzed for hours, even days.

Although Speed Stingers are incapable of generating flames, they make up for this deficit with several hidden abilities. Being nocturnal, Speed Stingers are blessed with amazing night vision. Additionally, when running at full velocity, a Speed Stingers dexterous feet allow the dragon to tread up walls and even run upside-down on ceilings and cave-tops for limited periods of time. Finally, these dragons have developed incredibly thick hides to protect them from the heat and friction when they race at top speed. This calloused skin renders Speed Stingers impervious to temperature extremes as well as traditional weapons like arrows and spears."

Egg
The Speed Stinger's Egg in School of Dragons and Rise if Berk have appear to have a swirly pattern that radiates from the middle. It is tan in color and has little stripes on each layer of the swirl. Because of the distinct segments on the swirl, it resembles the pattern of some sea shells.

Hatchling to Adult
The Speed Stinger is a swift, flightless dragon which resembles a featherless theropod Raptor/dinosaur. Even though it's flightless, with sail-like appendages on its head, back and legs, the Speed Stinger does have wings, these are very small and useless. Its name is derived from the barbed stinger at the tip of its tail (rather like a stingray's). All of them have red stingers and red eyes. Their small pupils resemble those of Terrible Terrors. They also have muscular back legs with webbed feet. Average Speed Stingers are green, while the leader has red stripes and highlights, and is slightly bigger than the rest of the pack.

Titan Wing
Titan Speed Stingers develop a second pair of small wings and their tail becomes thicker. Their skin turns into a deep shade of fuchsia and their fins, a hue of glossy dark blue. Instead of red, their eyes turn yellow.

Abilities
Although being flightless and lacking firepower, Speed Stingers are known to be one of the most dangerous and aggressive dragons.

Intelligence
Speed Stingers have shown to be very intelligent, as they work in packs and can plan attacks.

Keen Vision
Speed Stingers have excellent and powerful night vision where they can see perfectly at night and even through a minor snowstorm.

Paralyzing Sting and Accuracy
Young and adults of the Speed Stingers are very accurate to use their stingers on their prey though with the lack of understanding metal proof armor.

Adult
The sharp stinger on the end of its barbed tail contains a powerful venom that can paralyze a victim entirely in just one sting. The sting eventually wears off, some in hours, others in days, depending on the amount of venom injected.

Adolescent
An adolescent Speed Stinger's venom is not fully developed as it can't paralyze an entire victim on one sting. Instead, the venom only works around the area of the sting, leaving the rest of the body movable and operational.

Endurance and Stamina
Due to the high energy of their running, Speed Stingers have highly calloused skin that can protect them from fire and make them impervious to arrows and spears. Their speed produces plenty of friction, and heat, thus they have thick hides. Speed Stingers have high stamina, as they are able to run very long distances and hunt down their prey without any sign of fatigue.

Speed and Agility
Speed Stingers lack any flame usage. This is because all the internal flame energy goes to its powerful legs, which give it its speed, agility, and the capacity to jump high. With high speed on their side they are the fastest land runner of all dragons. As they fast enough to be almost invisible traveling at high speed. As one of the most agile dragons, their speed allows them to gain enough velocity to run up walls and even run upside-down on ceilings for a short period of time.

Hunting and Scavenging
In pack they will run large circle to trap their prey to make them unable to flee as they can strike the prey to make them paralyzed or they can attack for big ambush by running to the bushes or dark shadows to strike.

Stealth
Speed Stingers are very stealthy as they are able to use their speed to get around Vikings or dragons easily without being noticed, until they attack.

Lead Speed Stinger Abilities
The Lead Speed Stinger is the largest Speed Stinger is a pack. It has been known to be the most aggressive, agile, strongest, and intelligent, and has dominance over the rest of the pack. A Lead Stinger has been seen to go against a Night Fury, which shows its aggression. It is able to dodge a Night Fury's attacks with its speed and agility.

Water Running
It is said by Fishlegs in Race to the Edge that the Speed Stingers living on an island near to Dragon's Edgehad developed webbed feet. This implies that the trait was either undiscovered before now or is only intrinsic to that group of Speed Stingers, as Hiccup later says it's proof of dragon evolution by adapting to their environment being very wetted and surrounded of the ocean, implying that the Speed Stingers in Defenders of Berk did not have this trait. This makes sense, as they only found Berk through use of an ice bridge, while the Speed Stingers in Race to the Edge had managed to track the riders all the way back to Dragon's Edge. Furthermore, the readiness of the Speed Stingers to cross the ice bridge implies that they knew there would be food upon crossing, meaning they could have known of Berk's existence for quite some time but had no access to it.

Behavior and Personality
The Speed Stinger is described as the Velociraptor of the Dragon World, being extremely intelligent and cunning. These dragons are ravenous scavengers, that will often steal from other dragons and Vikings but they probably also hunt. They live in packs, led by a Lead Stinger, and have a hive-like mindset. They hide under the shadows of the sun. The Lead Stinger decides everything, and the pack follows wherever he goes; without him or her, the pack becomes useless. When attacking, they leap in the air and use their stinger to paralyze their victims. Any member of a Speed Stinger pack would be very loyal to their pack, and protect them at all costs, even from its own kind, or previous pack.

As nocturnal dragons, these creatures sleep in dark, remote caves through the day, and wake up the moment the sun sets. These pack dragons sleep in large numbers, mainly for defense. Like the Stormcutter and Night Fury, Speed Stingers are able to hang themselves or sleep upside down like a bat. Due to their high metabolism, they sleep throughout the entire day to conserve energy as they expend close to all of it when they hunt.

These dragons are incredibly aggressive, seemingly untrainable. They are resistant to the technique of approaching them slowly and then placing a palm against their snout. These dragons, due to their speedy reflexes and hostile nature, are very unpredictable. It is nearly impossible to tell when they will strike.

However, they do have a softer side. They are incredibly protective of their leader, young and other pack members. Often displayed when the pack goes great lengths to save a downed leader, and the latter likewise. They even go in search of their missing young across several islands. But these dragons have been shown to respect their pack's opinions. If a member chooses to side with an opponent, or leave the pack, the leader and the rest of the pack will come to a unanimous decision to let him be.

Training
Speed Stingers were said to be too aggressive to be trained. However, in School of Dragons, it is revealed they can be trained, though only at a young age.

During an Icestorm Island quest, the Headmaster decides to train a Speed Stinger since they can't fly. He is unable to do so, even though the player does earn the trust of the pack from a previous quest. Another Icestorm Island quest reveals that Speed Stingers will not be aggressive if one earns their trust, such as returning a lost juvenile of their kind. In The Next Big Sting, Hiccup trained an adolescent Speed Stinger, Speedy for a short while before he returned to his pack.

If trained, Speed Stingers will stay to protect its trainer, even if it means leaving their old pack. Any friend of its trainer would be considered a pack member, and even when a trained Speed Stinger does not like an individual, for example Speedy to Snotlout, the Speed Stinger would remain to protect the individual if he/she is considered as a pack member.

It is also quite possible that, if they are found as an egg, the Speed Stinger can be trained like any other hatchling dragon, as they will believe you are their parent or their alpha.

How To Train Your Dragon
The Speed Stinger is found in the Dragon Manual when Hiccup was searching for information on Night Furies.

Dragons: Defenders of Berk
The Speed Stinger made it first physical appearance in Frozen, when an extreme blizzard that froze the ocean. While Hiccup and Toothless were searching for Trader Johann, they could see a pack of these dragons running beneath them, on the frozen sea. It later turned out the Pack had taken over Berk, and paralyzed most of its citizens, including Stoick, Snotlout, and Meatlug. Ultimately, Toothless and Hiccup managed to lure the Stingers away from Berk, by capturing their leader, the Lead Stinger, luring it back along the path and forcing the other Speed Stingers to follow until Hookfang- ridden by Snotlout with Gustav Larson acting as his arms due to his paralysis- was able to melt the path and leave them trapped.

Dragons: Race to the Edge
In The Next Big Sting, the gang found an injured adolescent Speed Stinger. After much consideration, the gang decided to bring it back to Dragon's Edge. After Fishlegs nursed it back to health and trained it, the Speed Stinger grew close to the gang, except for Snotlout and Ruffnut. The riders named the Speed Stinger 'Speedy'. Fishlegs then learnt that Speed Stingers evolved webbed feet to travel from island to island. Meanwhile, Speedy's pack hopped from island to island in search of him. Ruffnut and Snotlout, enraged by Speedy's aggressive behavior towards them and stinging their dragons, decide to kidnap and abandon him. Fortunately, the rest of the gang caught up, only to see that Speedy's pack had arrived. After defeating them, Speedy grew closer to the entire gang. He reluctantly left the riders and joined his pack after some persuasion.

In Last Auction Heroes, the Dragon Hunters also captured several speed stingers for their Dragon Auction on their Island. All of them were freed when Hiccup and the gang arrived.

In Defenders of the Wing, Part 1, Mala told Hiccup that she would only trust the dragon's judgement of him. Throk then pushed him into a nest of Speed Stingers. He attempted to train them by reaching his hand out, but the Speed Stingers attempted to strike him and cornered him. However, Toothless swooped in and blasted at the Speed Stingers, sending them scuttling away.

School of Dragons
The Speed Stingers in this game can be found on Icestorm Island, running in packs. Later, these dragons were available for riding.

Trivia

 * The Speed Stinger strongly resembles the Stinger Dragons from the How to Train Your Dragon Arena Spectacular. The resemblance and name similarities are notable enough to hint that the dragons may be the same species just in different forms of telling the story of the How To Train Your Dragon Universe.
 * The Speed Stinger's roar uses the same sound effects as the "Velociraptors" in the Jurassic Park films. This is most likely due to their resemblances.
 * The Speed Stinger's tail resembles a scorpion's stinger, or to be more accurate, a stingray's tail.
 * Although it did appear in the dragon manual in the movie, it did not appear in the short Book of Dragons. The image may have been put in the book to fill in space, but was later embraced in Defenders of Berk.
 * The Speed Stinger is one of the very few dragons that does not have a horn on its nose or a horn-shaped nose.
 * Speed Stingers are the only dragons that do not have a fire type, however, in School of Dragons, they shoot a type of acid. This is most likely due to many feature in the game require a dragon's firepower. This is also a reason to the fact that Speed Stingers use internal energy for their leg muscles, while fire breath requires a lot of energy, acids do not.
 * The Speed Stinger is the first dragon in the series to be flightless. The second being the Bewilderbeast, and the third the Cavern Crasher.
 * Despite Fishlegs saying one drop of their venom can freeze a human or dragon in an instant, it took six Stingers to paralyze Stoick. This could mean their poison can be counteracted by either sheer adrenaline, body size or both, although this might just mean it took six dragons before one of them could sting him. The latter is most likely the right one. This dragon's venom may act a bit more slowly the bigger the animal or person its acted upon. Such as when Stormfly received a single sting, it took a few seconds to paralyze her completely. Also when the first Speed Stinger attack happened, it took four Speed Stingers to instantly paralyze Flystorm, a Deadly Nadder that they had cornered.
 * They are one of the fastest dragons in terms of their overall speed, 13, and are also excellent at stealth.
 * Although this dragon is not the first dragon unable to breath fire, it is the first to have no ranged attack.
 * It looks like a combination between a Velociraptor, a shark, and a scorpion.
 * Their teeth reach further back when compared to other dragons.
 * The Speed Stinger resembles the fictional dinosaur species Acceraptor from the TV Show Terra Nova, since they both have sharp weapons at the edge of their tails.
 * While Speed Stingers are untrainable full grown, they can be trained at a young age.
 * While clearly based on "Raptors", the Stingers forearms resemble those of a T. rex.
 * The official stats for the Speed Stinger are most likely inaccurate, such as its speed 30, which most likely means the speed on land (since it only moves on land), although this has never been seen before, it is not as fast as a Night Fury and a few other dragons. Meaning that the speed 13 from the Cartoon Network stats would be its overall speed.
 * The stealth 30 is also another issue. Even though it has excellent stealth, they have not yet been proven to be better at stealth than a Changewing.
 * Speed Stingers can adapt to live in cold environments such as the Arctic. A pack of Speed Stingers were encountered in Icestorm Island.
 * Speed Stingers are very similar to Night Terrors.
 * Both hunt in packs.
 * Both are led by a leader.
 * Only the lead dragon has a distinct appearance.
 * They are both nocturnal.
 * Both don't know what to do without the leader.
 * The Speed Stinger egg looks very similar to a snail shell. They could also be based on ammonite fossils.
 * The Speed Stingers from Race to the Edge are quite possibly a second subspecies to the Speed Stingers seen in Defenders of Berk due to their water running ability and being slightly smaller than the ones in Defenders of Berk.
 * When the Speed Stingers were first released in School of Dragons there existed a glitch in which you could make them fly.
 * A Speed Stinger's tail strike is strong enough to break bones, as seen in Defenders of the Wing Part 1.
