- Dragons: Rise of Berk

Development
The Windstriker 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, Thornridge, Threadtail and two other Unknown Dragons.

Egg
A Windstriker's egg looks like a bean. It has teal, yellow, and white stripes covering it with multiple curved thorns on it.

Hatchling to Adult
Windstrikers come in a wide variety of colors. Windstrikers have a long, slender neck and jagged-edged wings They have several spikes on their tail and neck, and a large one on the tip of their snout.

Titan Wing
Although the titan Windstriker does not have much differences as compared to adult, there is a major change in color. Titan Windstrikers are glossy blue in color. They have a longer horn on the top of its snout and two large horns on their chin. The patterns on their body have been reduced to small white spots.

Super-heated Air
The Windstriker can produce large amounts of super-heated air to attack its opponents. It is possible that the Windstriker heats air up with its fire and then, direct it at its opponents. A Windstriker's air is hot enough to set its foes ablaze.

Fire
Although the Windstriker is not known to use fire to attack others, it uses fire to light up and illuminate dark caves.

Skydiving
Similar to the Night Fury and several other dragons, the Windstriker has the ability to skydive, a maneuver not all dragons can master.

Trivia

 * It is the third dragon with an axe-shaped head.
 * It is the first dragon with "wind" in its name, the second one being the Windgnasher and the third one being the Windwalker.
 * The Windstriker looks strikingly similar to a Razorwhip. This could just be a coincidence, but it might mean that these dragons are somehow closely related. They are both Sharp Class dragons.
