The Thornridge is a large Sharp Class dragon that first appeared in How to Train Your Dragon 2.

Official Description

These Dragons are the silent but strong type. They're more comfortable in the background, but are always ready to swoop in when someone or something they care about needs help.
As in life, the Thornridge prefers to stay back and fight from the shadows. It will only go to the front lines if it senses a comrade in danger.
  Dragons: Rise of Berk  


The Thornridge was created using a modular system to mix and match preset body parts onto different dragons. It was created from the same base that was used for the Hobblegrunt, Raincutter, Threadtail, Windstriker, and two other unknown dragons.

Physical Appearance

Thornridge eggs look like an upside down triangle as it has a smaller base and a wider top. They have rows of spikes that run down vertically. The spikes closer to the top tend to be larger than those closer to the bottom. The egg looks very similar to a Singetail's, although they don't really share any further features.

Hatchling to Adult

Thornridges are a long and slender dragon with short limbs and big wings. They have long tails and long necks. They have a twin nose horn that makes a "V" shape, and a solid crest with spiral horns. They have a pair of big eyes at the front of their skulls. They come in all sorts of colors with blotchy markings and paler underbellies. They have a few spines running down from their necks to tails and their tail splits slightly at the end.

Most Thornridges breath orange-yellow fireballs, however some individuals like Thornshade have displayed unique thick streams of yellow-green fire. Thornridges are also capable of holding fire in their mouths to illuminate dark places.

Strength and Combat

Thornridges are able to carry humans on their backs and longboats that are loaded with a multitude of objects without any signs of struggle.

Behavior and Personality

How the trap works.gif

The Thornridge is an incredibly shy and quiet dragon, preferring to remain in the background. This dragon hates getting involved with activities and fights, but will readily help if it means saving its home and friends.

Despite this shy personality, some Thornridge individuals, such as Warywing, are quite social with other dragons, even different species. Even so, Warywing is still scared of Vikings, children, and sheep.

Thornridges were seen in abundance in Valka's Mountain, one of which greeted Hiccup and Toothless when they arrived. They later fought in the battle against Drago's army. A Thornridge was caught in a dragon trap, but was fortunately freed by the Dragon Riders. After Drago's Bewilderbeast defeated Valka's, all the Thornridges fell under its control and bowed to their new Alpha. After they were freed by Toothless from the Bewilderbeast's control, they fought against the giant dragon. In the aftermath, they bowed to Toothless, acknowledging him as their new Alpha.

How to Train Your Dragon: The Hidden World

When the people of Berk decided to move to the Hidden World, all the Thornridges of the island began the journey too, carrying different things, such as ships. They eventually arrived at New Berk, where they settled down for a while.

Many wild Thornridges were among the myriad of dragons in the Hidden World who bowed down in front of Toothless and the Unnamed Light Fury, showing respect for their Alpha.

After Grimmel the Grisly captured Toothless, all the Thornridges from Berk, along with the other dragons, came to their Alpha's help. However, Toothless ordered them to stop when Grimmel threatened to kill the Light Fury.

Fortunately, the Dragon Riders began an attack on Grimmel's ships and freed the Thornridges, along with the other dragons, which returned to New Berk.

When the battle ended, Hiccup realized that the only way the dragons can be safe from humans was for them to go to the Hidden World. After Toothless gave the command to the dragons of Berk, all of them, including the Thornridges, said their farewells to the Vikings and flew off to the Hidden World.
