Now with your champion dragon, the fights are over before they start. [src]
  — The arena host talking to Ryker Grimborn about the Triple Stryke  

The Triple Stryke is a medium-sized Strike Class dragon that first appeared in Dragons: Race to the Edge.

Official Description

Vicious. Aggressive. Belligerent. These are only three of the words that describe the Triple Stryke in battle and the incredible fury it unleashes with its trio of braided tails. Displaying an ornery disposition from the beginning of their lives, Triple Strykes make the ideal champions in underground combat arenas. With their barbed hides that deflect attacks, their intense fire blasts that blind opponents, and their tail triad that braids into a single powerful weapon, a Triple Stryke wins most bouts on intimidation alone. But victory sometimes breeds vanity and exploiting this overconfidence is often the only way to defeat a Triple Stryke in battle. A Triple Stryke's braided tail is a force to be reckoned with, but each tail produces a unique venom: A sting from the first tail numbs combatants, the second disorients them with mild hallucinogens, and the third creates an agonizing of burning in your very blood.
This giant Strike Class Dragon's three tails can slash through its enemies or snake around its prey. When confronted by one, the best thing to do is turn tail and run! Beware of this Dragon, Vikings! Once it has you in its sights, it's nearly impossible to it shake off your tail.

The Triple Stryke was mainly based on scorpions in terms of appearance. A piece of concept art depicts the Triple Stryke with an underbite, a characteristic which was later dropped. The ear-like appendages were intended to be much larger and the dragon had much more spikes on its head.

Physical Appearance

Triple Stryke Egg.png


In Rise of Berk, Triple Stryke eggs are a dark red color, with almost black sections in the middle. They are smooth, shiny, and oblong shaped with some small nubs on them.

In School of Dragons, the eggs have the same appearance and color, but they more round, like most eggs in this game.

Hatchling to Adult

The Triple Stryke is a stockily built, arachnid-like, bipedal and seemingly digitigrade dragon with armored plates on its back that resembles an armadillo's and two legs. It has two large ear-like appendages on its head and a pointed nose. The most notable feature is its thick, braided tail that can unwind and split into three thinner ones. Each tail is made up of many round segments and is equipped with a scorpion-like stinger, though some individuals, such as Syringaca, have egg-shaped structures on their tail tips instead. Their forelimbs act as pincers, which also resemble that of a scorpion.

Titan Wing

Titan Wing Triple Strykes have two pairs of horns on their heads, as well as larger and sharper dorsal spines. Their tails have silver, gold and bronze tones, with details on its orange wings and different designs on their body and wings.


Triple Tails

The Triple Stryke has triple tails, all three with stingers at the end and all that can braid into one dangerous tail.

On the tip of each of the Triple Stryke's three tails, there is a stinger, each one producing its own unique venom: The first numbs opponents, the second disorients them with mild hallucinogens, and the third creates the agonizing sensation of your blood burning. Triple Strykes use their tails as their primary source of attack and defense, as they prefer not to use their fire as much, as it requires a lot of energy.

Some Triple Stryke individuals, such as Thorntail, posses unique toxins in their stingers that overwhelm their victims with the scent of flowers.

Tail Whipping

The Triple Stryke's tails can also be used as a whip if they are not in a position for stinging. When the tails are combined, they can effectively whip or smack the Triple Stryke's opponents. The Triple Stryke can whip a total of three Vikings with its tails, each is powerful enough to smack a Viking. Unlike stinging, which is mainly used for attacks, tail whipping is mainly used for defense, as seen when Sleuther was defending Dagur and Shattermaster from the Dragon Hunters in "Shell Shocked, Part 2". But they can also be used for offense, as when Sleuther smacked Stormfly in the face.

Prehensile Tail

The Triple Stryke's tail is prehensile, which makes it able to wrap around objects and grasp them with one, or more of its tails. This can be used to hold dragons, Vikings, or other objects. If only one tail is used to grasp an enemy dragon, Viking, or its prey, it can then devour them or use its other two other tails to sting them.

Defensive Plates

Layered on top of its scales, the Triple Stryke is armored from its tail to its head (other than its belly) with barbed, defensive and strong plates which deflect attacks, such as things like spines and arrows. These plates also increase its endurance of attacks, such as things like slashes or fire blasts.

Triple Strykes shoot intense, continuous streams of bright orange flames. They can release large jets of fire because of their wide jaws. They also appear to be highly concentrated in fuel, as the flame gives off a bright color. The flames can also be shot as short fire blasts that are more fit for destroying objects, as they have been seen to easily and quickly explode wooden shields. It is also said that the Triple Stryke's fire is able to blind its opponents.

Strength and Combat

Tumblr p85e3m2LrZ1u1x8wgo1 540.gif

The Triple Stryke has shown a lot of strength, especially in its tail. The lifting power of the Triple Stryke is strong enough to handle the weight of Toothless using only one tail without any struggle while grabbing him in the air. The Triple Stryke has also demonstrated this lifting power by using the combined strength of all its tails which acted like a hook to pull out a metal cage with a Razorwhip and Heather in it from the water and lift it out into the air during the events of "Sins of the Past".

The Triple Stryke is one of the few dragons shown to be able to take on a Night Fury even in a ring as small as the old dragon arena on Berk. According to the ringleader from the Dragon Arena, the Triple Stryke is able to defeat dragons in under five minutes. It was shown to have even beaten a Speed Stinger.

Speed and Agility

Sleuther's playfull side.gif

As a Strike Class Dragon, the Triple Stryke is an incredibly fast dragon. It shows great aerodynamics and agility during flight, being able to fly upside down and do flips.


The Triple Stryke has a barbed hide, which protects it from attacks. As it was able to take the attacks from Toothless, it was able to fight for a long period of time and able to fly a long distance with him.


Being in the Strike Class, Triple Strykes are highly intelligent, as shown when Sleuther follows the hand commands of Dagur. He was also able to understand Dagur's whistling command. He even went to his rider's side when Snotlout mocked Dagur's name, rattling his tail to tell Snotlout to back off.

Defense Roll

Tumblr p2y3vudSBR1vpniolo4 400.gif

The Triple Stryke has been seen to often perform a fast spinning roll as it comes into battle, similar to Hideous Zippleback dragons. The roll can be used for defense as it has a thick hide, and its underbelly won't be exposed.

The Triple Stryke can also use this for an ambush attack, as its spins really fast before landing and striking its opponents with its tails, without being noticed or harmed. It can also be used if the Triple Stryke needs to get near its opponents without getting injured.

Tail Rattle

Triple Strykes have been shown to be able to make a rattle with their tails, similiar to that of a rattle snake. This was first only thought to be able to be done by Syringaca In Dragons: Rise of Berk , however, it was confirmed to be a natural ability, as shown by Sleuther in "Something Rotten on Beserker Island", after Snotlout teased Dagur about his name, and Sleuther frightened him off.


The Champion Triple Stryke seems to be able to both breathe acid mist and to shoot the same mist from their tails. It is unknown if other Triple Strykes can do this. It is possible that the mist from the tails contains the typical venom in the stingers of other Triple Strykes.


Some Triple Stryke individuals, such as Thorntail, have specific coloration on their body that enables them to blend in with the spring flowers around them, enabling them to bide their time while waiting for their prey.


Triple Strykes can be very vain and over-confident, and these can result in their own downfalls during combat.

As seen in "Blindsided", the Triple Stryke makes a clicking sound with its tail right before it attacks. Those who can hear the sound can anticipate the Triple Stryke's next move (considering that it is an attack with its tail).

The Triple Stryke's underbelly is weaker than the rest of its body, meaning that an attack on the underbelly could result in serious injury.

Behavior and Personality

Triple Strykes are merciless and formidable, stopping at no cost to destroy their opponents. Their sheer confidence and intimidating stature are enough to scare other dragons. With its incredible skills, these dragons are arrogant and sometimes over-confident, loving to flaunt its abilities. These dragons are vicious and relentless, as displayed when it continuously attacked Toothless, and attempted to kill a Dragon Hunter. They are also rather scrappy, willing to pick a fight with any other dragon. As shown by Sleuther, they don't give up easily and refuse to accept defeat constantly coming back to sprawl.

These dragons, however, are quite misunderstood. While seemingly merciless, these dragons do repay their debts and are incredibly grateful. They will stop at no cost to express their gratitude and respect. This is shown when Sleuther was spared by Toothless. Instead of killing him, he stood up and cast a seemingly confused yet thankful look. When the Hunters broke in, he immediately prepared to defend Toothless, but when the latter told him not to kill a hunter, Sleuther obeyed with respect.

  Astrid, upon noticing how hard it was to train Sleuther  

These dragons are fierce and vicious, thus they are extremely hard to train. However, these dragons do repay their debts. If shown mercy and kindness, the dragon will treat you with respect and compassion and will stop at nothing to protect you.

As seen in "Blindsided", the Triple Stryke can also be trained by clicking and clacking objects together, as it sounds like the click that the dragon itself makes. As Triple Strykes usually do not welcome humans near them, the tricky part is getting close enough to one to train it. Clacking the objects ensures that the Triple Stryke will calm down and allow the Viking to come closer and to touch its head.

Tumblr odr0w0QEOY1uafym8o1 r1 540.gif

In "Stryke Out", a Triple Stryke was the champion of a Dragon Fighting arena owned by the Dragon Hunters. However, fans got tired of the Triple Stryke's constant quick wins and attendance began to drop. Ryker demanded that the manager find a way to make the fights entertaining again. It was rescued by Hiccup and Toothless later on, returning with them to Dragon's Edge
