- "It's a myth, it doesn't even exist!"
- ―Stoick talking about the Boneknapper
Sometimes, this bone armor can be essential for the dragon to perform basic actions, such as roaring. The Boneknapper will often go to extreme lengths to find the bones it seeks, hunting down the fragments for years. However, the dragon does have a docile side to its nature as well, as with most dragons around Berk.
A member of the Mystery Class, Boneknappers are built in a similar birdlike manner as the Deadly Nadder, albeit much larger. Their natural coloration seems to be a dull olive-green and gray, though it can be hard to see under their armor of bones.
Unlike most dragons, which have hard scales to protect themselves from enemies, Boneknapper scales are thin and soft. To counter this weakness, Boneknappers cover themselves in the bones and horns of dead dragons and other animals. As a form of defense, they can use a huge concentration of bones, forming a club at the end of their tail to disarm or injure opponents.
- "It searches for the perfect bone for its bone armor."
- ―Hiccup, in Legend of the Boneknapper Dragon, realizing the Boneknapper found the perfect bone on Gobber's belt.
The Boneknapper's main objective is to collect bones to protect itself. Gobber's Nemesis is special, since he will do what ever it takes to get the Terrible Terror pelvic bone, even if it means that he has to risk his own life to get it.The Boneknapper is known to create skeleton armor from the bones of other dragons. As their armored body can protect them from attacks for great defense. They are able to create a club tail out of bones for smashing their opponents. It is also confirmed that as long as their objectives to collect perfect bone pieces is fulfilled, Boneknappers can be very calm and friendly towards human beings. Boneknappers seek the strongest bones for their armor. So every year they discard their old bones and find newer, stronger bones to use for their armor.
They can breath bursts of fire that are as large and powerful as that of the Red Death. It does not appear to be very hot as the gang was shown to be able to stay very close to it and the dragon ribcage that got burned was not charred.
Their stamina, as shown in The Legend of the Boneknapper Dragon, is very high to be able to fly and run well for long distances and show no sign of struggle.
Strength and Endurance
Their size is large and they have shown amazing strength to be able to hold many Vikings on their body and travel while also wearing its bone armor.
They even have the ability to make a powerful roar that needs a special piece of bone, acting as a throat bone on its body in order to be released. This roar can also used as a mating call that can attract others of their kind.
Without their bone armor, the Boneknapper is as weak as a boneless chicken and is vulnerable to their enemies attacks.
According to Dragons: Rise of Berk, the Titan Boneknapper has orange, pinkish skin with many brown dots on its wings. They still retain their bone armour and most bones remain the same. However, the clubbed end of its tail becomes a smaller, sharp dragon skull.
The Boneknapper makes a brief appearence in the How To Train Your Dragon film. After Dragon Training, Hiccup reads through the Dragon Manual in order to find information on the Night Fury and ends up finding a page about the Boneknapper as he flips through the book.
The Boneknapper appeared as the main antagonist in Legend of the Boneknapper Dragon, a 15 minute short created for the release of How To Train Your Dragon on DVD. Originally having hunted down Gobber since his teen days numerous times, the Dragon made its first physical appearance on a distant island after Gobber, along with Hiccup and his friends, set out to capture it. Hiccup realizes that Gobber's belt buckle is the piece of bone that the Boneknapper wants, which is missing from its neck. Reluctantly, Gobber gives the piece of bone back to the dragon, where it suddenly becomes quite docile and playful. As a thank you, the Boneknapper lets Gobber, Hiccup and the others ride on its back to get home. With its armor complete, the Boneknapper let out a triumphant roar, drawing other female Boneknappers to follow its mating call back to Berk.
The Boneknapper and its abilities were mentioned in Book of Dragons.
