When was the last time you saw a boulder roll uphill? [src]
  Hiccup worries as the Catastrophic Quaken rolls uphill  

The Catastrophic Quaken is a large Boulder Class dragon that first appeared in Dragons: Race to the Edge.

Official Description

The Catastrophic Quaken can smash into the ground and create huge shockwaves that can knock dragons out air.
As a Boulder Class dragon, the Catastrophic Quaken is literally what it eats — as it enjoys the consumption of rocks. This dietary preference is the cause for its tendency to reside in rocky terrain where it can roam afoot and pick up sustenance as it travels. Strong and hulking, this dragon relies on its size as the ultimate defense mechanism. When threatened, its immediate reaction is to enter protective mode and roll into a ball like a giant armadillo. Once secured into this position, it quickly takes the offense, smashing into the ground to create huge shockwaves they will knock dragons down whether they are on land or airborne. A lack of human interaction has made these dragons cautionary over time, but since Hiccup and the Dragon Riders have introduced them to humans they are slowly becoming less stony and more caring.
Catastrophic Quakens are known for their cruel attitudes. They don't let anyone get in their way, and they'll go out of their way to wreak havoc on their target.
Catastrophic Quakens eat more rocks than any other in their class! They also have a nasty habit of spitting up digested rocks at attackers in the form of hot lava!

For every healer, there is always a tank to help withstand the pressure of life's obstacles, take the heat and charge into battle with a mighty barrel roll. Who better to do that than the Catastrophic Quaken? Now on sale at the Trading Post today!
Strong, territorial, and incredibly loyal, this Boulder Class dragon has it all with the wonders of a symbiotic relationship with the Prickleboggle. We all know how protective it is to its healer last time, but did any of you expect the reverse to happen between these best of winged friends? Astrid certainly didn't, until she had to go looking for Dragon's Edge's popular healer yet again.
Just as Astrid and Stormfly were heading to Hiccup and the rest of the motley crew, they almost crashed right into the Prickleboggle! Understanding that it needed to guide them elsewhere, they quickly followed the Prickleboggle to Dark Deep, where they found the Quaken making a mess of the rocky terrain in an attempt to protect its nest from a band of dragon hunters.
After they made short work of those thieving Dragon Hunters, it took a bit of coaxing to get the Quaken and its eggs back in the safety of Dragon's Edge. Thinking that it's always better to work in numbers, though, Astrid felt that they need Trader Johann's help again in enlisting Vikings like you to be caretakers of this stubborn dragon's eggs. Are you up to the task? Stop by while the sale lasts!

Physical Appearance

In School of Dragons, the egg is a regular oval-shaped egg. It has layers of greyish brown and tan stripes on it and grey spots all over it.

In Dragons: Rise of Berk, however, a Catastrophic Quaken's egg is brown and whitish tan, the same colors as an adult Catastrophic Quaken. It also has several spikes on its shell similar to an adult's. There also seems to be yellow oozing smoke coming out of it, a little-added touch. The globular patterns splashed across the egg's face seem to resemble those of the Quaken's underwings. It is also coated in round black spots, just like the dragon itself. In addition to this, the egg is a more rounded shape than they regular oval.

Hatchling to Adult

As one of the biggest dragons to appear in the series, the Catastrophic Quaken has a somewhat stubby body, stocky build and short stature, with rather small wings. This dragon also has dark gray, bumpy skin, akin to that of the Gronckle and the Hotburple. It is covered with spikes all over. The Catastrophic Quaken's head, body, and tail are covered in short spikes. Its lower jaw can split in two, with a tongue on each jaw. They are larger than most other dragons in the Boulder class, including the Gronckle, but smaller than a fully grown Screaming Death.

Titan Wing Catastrophic Quakens in Dragons: Rise of Berk have a dark purple hide with longer spikes concentrated around their tail, neck, and snout. They are much larger than their adult counterparts and have bigger and sharper spikes.

  Dragons: Rise of Berk Battle Text  

Catastrophic Quakens, like most Boulder Class dragons, eat rocks. Their love for these geological materials derive from their habitat in rocky terrains where they roam afoot and pick up sustenance while traveling. They also can produce a magma slobber from their jaws. When fully unhinged, their trifold jaws can ingest a plethora of rocks, which it subsequently spews out in the form of a molten lava stream. This ability has yet to be seen.

Curling into a Boulder

Catastrophic Quakens can curl up into boulders and roll into their intended targets in a form of attack or defense. They can also smash into the ground with powerful strength and create a shockwave strong enough to knock both dragons and humans off their feet, or out of the sky.

Strength and Jaw Strength

Catastrophic Quakens are very strong, considering their size and armor. They could easily break a boulder with their tails and cause rock slides by slamming their bodies to the earth. They are also the only dragons able to break a marble block. Their jaw strength is more powerful than that of a Gronckle.

Endurance and Stamina

CQ's Endurance.gif

Catastrophic Quakens are incredibly tough, as they are able to withstand many attacks, especially when curled up. Even a Night Fury's plasma blast couldn't stun or harm them when rolling. They are able to roll through the ground for a long period of time without showing any signs of exhaustion. They are also able to crash through thick marble walls and have no adverse effects from this.

Quakens are smart enough to use tunnels that are big enough for themselves to curl up into boulders to attack their enemies or to use their strength to cause rock slides. They are also smart enough learn to respond to vibrations and to understand that by releasing the volcano pressure, they could stop the lava from flowing.

Speed and Agility

Quakens can travel in greater speed when they curl like boulders. They are also able to walk on their hind legs.


As Boulder Class dragons, Catastrophic Quakens are able to seek out specific rocks and minerals and dig for them. This is evidenced in Dragons: Rise of Berk where the individual named Aurum can mine for gold.


Most Catastrophic Quakens are various shades of brown and grey, and altogether very rock-like. They blend in well with rocky surroundings, especially when remaining motionless. A few individuals are more brightly colored, however, such as Melonquarry whose color resembles that of a watermelon

Due to their massive size, Catastrophic Quakens can get easily trapped in tight spaces, as shown in "Between a Rock and a Hard Place", when a Quaken couldn't move at all when it fell between two walls of rock with little space between them.

Behavior and Personality

CQ The bully of Dragons.gif

This dragon is described to be the 'bully of the dragon world'. Extremely lonely and cautious towards humans due to a lack of interaction with them, Quakens are unlikely to bond with just anyone. They tend to have very limited contact with humans and other dragons, making them distrusting and destructive. However, their loyalty can be earned by slowly and calmly introducing it to humans and other dragons. Once you do that, it becomes quite an agreeable animal, and as with most dragons, will not hesitate to look after you and return the favour.

The simbyotic relationship between CQ and Gronckles.gif

While they can be rather hostile, this dragon appears to be rather friendly and loyal at times. According to School of Dragons, Catastrophic Quakens have formed a symbiotic relationship with Prickleboggles, with the Catastrophic Quaken protecting the Prickleboggle from harm, and the Prickleboggle healing the Quaken if it is injured during a fight.

The Catastrophic Quaken have also a symbiotic relationship with Gronckles as stated in "Living on the Edge".

According to School of Dragons, these dragons surround their nests with large boulders in order to protect them from other dragons, rather like a fort barricade.


Due to their reclusive behavior, Quakens are hard to train. However, once a trainer asserts a certain level of trust with

the dragon, as well as befriends them, Quakens are easy to train and will not hesitate to help the trainer too. They are also professed to be extremely loyal once their trust has been earned.

In addition, Quakens can be easily trained in the face of an authority. This can be shown when a Dragon Hunter and Fishlegs could command, or rather, instruct, two Quakens with a giant hammer. This higher authority, however, must be based on mutual respect and trust, instead of a strict demanding force, or the Quaken will simply ignore any commands.

Comparative Statistics


Dragons: Race to the Edge

Season 1

Main article: Tormentor

In "Quake, Rattle and Roll", Hiccup and Fishlegs visit Dark Deep upon learning about the existence of this dragon via the Dragon Eye. When they visit the island, they were faced by hostile wild Gronckles. Following that nasty encounter, attacked by a new species of dragon which Fishlegs dubbed the 'Catastrophic Quaken'. Fishlegs then attempts to train the Quaken alone. Meatlug immediately steps up to defend him and make friends with the Quaken. Eventually, with more contact with humans, the Quaken starts warming up and befriends the Gronckles on Dark Deep.

Season 3

Main article: Enslaved Quakens

In "Between a Rock and a Hard Place", the Dragon Hunters then captured a pair of Quakens and used to acquire shipments of marble rock from island. They were able to control the Quakens by using hammers to command them to break up the marble quarry. This brainwashed them into be willing slaves of the Dragon Hunters. They were also able to force them to fight Hiccup, Toothless, Fishlegs, and Meatlug and return to the Hunters. However, Fishlegs saw that they were friends and was able to use one of the hammers to convince them that he and Meatlug were their friends. Together, Fishlegs and the other riders led the Quakens to Dragon Hunter Island where he told them to demolish the Hunters' marble fortress. They were then taken to Dark Deep. In "Last Auction Heroes", the Dragon Hunter chieftain Viggo Grimborn had a Quaken in a cage for his Dragon Auction. However, it was freed by the Dragon Riders.

Season 4

In "Gruff Around the Edges", a Quaken is sleeping in a cave, only to be accidentally roused up by Gruffnut Thorston.

Season 5

In "Living on the Edge", the Dragon Riders inadvertently have the three Quakens in Dark Deep helping them in preventing lava from destroying Dragon’s Edge.

Season 6

In "King of Dragons, Part 2", Catastrophic Quakens and thousands of other wild dragons are summoned by the Berserker Bewilderbeast to defeat the Dragon Hunters.


Dragons: Rise of Berk

This dragon appeared in Rise of Berk, along with two other individuals, Tormentor from Dragons: Race to the Edge, and Spikeback, an extremely unique looking Quaken with purple quartz-like spikes. Later, other characters such as Aurum, Melonquarry, Champion Catastrophic Quaken, Four-Man, Blawberry, and Liberated Trolboulder were added to the game as well.

School of Dragons

This dragon became available in School of Dragons as a rideable and customizable dragon in September 2015.

Catastrophic Quakens also appear in the maze activity "Loki's Mirage", where the dragons roll up into a boulder and roll down tunnels that the player must avoid.

Dragons: Titan Uprising

The Catastrophic Quaken was released as a playable species in this game in March 2021. Five characters were introduced to represent the species: Glaciated Quaken, Ice-Tongue Quaken, Cryoconitemare, Meltwater Kryal, and Lethiferous Cromlech.


  • 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 Dragons: Race to the Edge. Based on the Model Sheet for the Catastrophic Quaken along side other known dragons in the series such as Meatlug, this dragon should be 45 feet (13.72 meters) long and have a wingspan of 63 feet 7 inches (19.38 meters).
  • This dragon used to be known as the Catastrophic Quake, but, for some reason, an extra "n" was added to the end of this dragon's name. This may have been to make the dragon's name sound like "Kraken".
  • Like the Hotburple and the Groncicle, the Catastrophic Quaken is closely related to the Gronckle.
  • The Catastrophic Quaken was named by Fishlegs, but it was often referred to as just the Quaken.
  • The Catastrophic Quaken, as a species, was confirmed to have existed way before production on Dragons: Race to the Edge even started. Its design was based off of Nico Marlet's concept art for Skullcrusher in How to Train Your Dragon 2.
  • It is possible the purpose of the Catastrophic Quaken's spines is to protect itself when it is curled in a ball. The spines could keep anything curious enough to touch it away, or they are just an adaptation. The purpose of the spines could also be to dig into the ground so the Quaken doesn't lose control, or to help it get a grip to roll uphill, as seen in "Quake, Rattle and Roll".
  • The Catastrophic Quaken has a large spine, like a bee's stinger at the end of its tail.
  • According to School of Dragons, despite having a rock diet, Catastrophic Quakens are still affected by the dragon root arrows.
  • Among real-life animals, the closest to that type of jaws is the snake. Although the snakes don't appear to have triple split jaws, their mandible is divided in to two and each can move independently and this is why they can swallow large prey.
