The Windwalker is a Sky Dragon that is used as a riding dragon in the How to Train Your Dragon Book series.

Physical Appearance

Windwalkers change quite a bit as they age. Infant Windwalkers are covered with both fur and feathers, and are a bit of an ugly duckling.

A newborn Windwalker is a rather extraordinary ball of feathers and fur and looks remarkably like a cross-eyed duckling mixed with an anxious wolf cub.

When young, the fur slows the dragon down and its ankles and wing joints are wobbly and bendy. However, as it grows the Windwalker slowly loses the fur and grows more sleek, and its flying ability improves as its joints firm up. If referencing the cover of How to Steal a Dragon's Sword, Windwalkers seem to take on a somewhat crocodilian appearance as they age.

At a young age, Windwalkers have larger eyes and ears, small horns, 5 curved claws on each foot, and small protruding saber teeth. They are covered with both fur and feathers, and are a bit of an ugly duckling. As an adolescent, the Windwalker begins to lose the fur and grow sleeker. It has not yet mastered flying, but still can carry a person and move swiftly on the ground. As an adult, the Windwalker grows a longer neck, darker scales, wickedly sharp, curved claws, and its maw now resembles that of a crocodile, with many of its teeth showing. The nose horn grows longer and its ears are smaller than when it was young. It can now seat 3 people whereas it used to have slight trouble carrying one. The Windwalker is truly impressive on maturation.

According to The Incomplete Book of Dragons, Windwalkers form a chrysalis at the age of seventeen years and emerge in six to seven months. The reader is left wondering what magnificent form the Windwalker has taken after this transformation. Because of this development timeline and the fact that Hiccup's Windwalker has not yet reached his Chrysalis stage, it would seem Hiccup and his Windwalker are roughly the same age — early to mid-teens — during the Book series.


High-altitude flying: Windwalkers are one of the few dragons able to fly into the thin upper atmosphere, and as an older adolescent can almost match a Silver Phantom in flight. As a mid-aged teenager, Hiccup's Windwalker "had turned into one of the swiftest, most maneuverable dragons in the Archipelago." It also has an advantage in flight, being small and sleek as it can execute sharp turns impossible for any other larger dragon.

Enhanced Senses: Windwalkers have excellent hearing and sight. Their nictitating membranes (third eyelids) are transparent, allowing the dragon eye protection but not compromising sight. They are able to speak Dragonese, though Hiccup's Windwalker is portrayed as mute. The Incomplete Book of Dragons also indicates that a Windwalker can produce either electricity or lightning bolts.

Speed: Windwalkers are faithful and fast, siding with humans during the Dragon Rebellion.


How to Twist a Dragon's Tale

The book introduces Hiccup's Windwalker, the only Windwalker seen in the series. He is still a juvenile and traumatized from being a slave on Lava-Lout Island.

How to Break a Dragon's Heart

Hiccup's Windwalker transports Hiccup Horrendous Haddock III to Berserker Island, where he is captured.

How to Steal a Dragon's Sword

Windwalker climbs Angry Mountain with Hiccup and sleeps during the Dragon Rebellion attack. He also helps Hiccup during the sword fighting competition and later flies Hiccup to safety from the Dragon Rebellion.

How to Seize a Dragon's Jewel

At the beginning of the book, Windwalker is with Hiccup, Toothless, and Wodensfang when they are attacked in the woods and Windwalker helps fight and then flies Hiccup away. A little later, Windwalker drops off Hiccup, Toothless, and Wodensfang at the Prison Darkheart and then is scared off by a human firing at him from the fort leaving Hiccup’s helmet. At the end off the book, Windwalker flies alongside the Deadly Shadow as they escape from the Prison Darkheart.

How to Fight a Dragon's Fury

Windwalker stays hidden for the first half or so of the book thinking Hiccup is dead. After he finds Hiccup, he flies Hiccup to fight Furious despite being afraid and Windwalker flies to avoid the Dragon Furious’s attacks. After the war ends, Windwalker flies Hiccup back to celebrate with the humans.

The Incomplete Book of Dragons

The life cycle of the Windwalker is discussed in this reference book. The Windwalker also appears in the 'Dragon Key' at the back of the book.


  • Toothless from the HTTYD Franchise might be based partially on Hiccup's Windwalker. Similarities include: extreme loyalty, about the same ages, black color, Hiccup's "riding" dragon, and a superb flyer.
  • Windwalkers reportedly smell like hot chocolate.
