Stormcutters are very intelligent and curious dragons from the How to train your Dragon movies.
Thanks to the unique body structures and heavy build, the Stormcutter is indeed a very sharp, formidable hunter and fighter. As their 'X-wing' beats up and down in sync and are probably used for extremely tight turns and maneuvers and for fighting foes. This body structure allows them to demonstrate accurate flight techniques such as navigating through narrow and complicated spaces, or hovering and even rest in mid-air. Having four wings allows for exceptional maneuverability.
When they walk, they use their lower wings as forelegs while holding their upper wings against their sides."They have the unique ability to rotate their heads about 180 degrees. By doing so, there is no way to hide from a Stormcutter. Stormcutters can shoot a sustained torus of fire which creates a tornado-shaped fire. They also have fore-talons on their wings that are hooked and can be used to pick dragon trap locks or destroy an entire war machine. Their sharp talons are helpful to climb on mountains even upside down."
