Here are three 3D dragon paper models, created by HP Creative Studio. All paper crafts are based on the film How to Train Your Dragon. The first is the Gronckle 3D Dragon. The Gronckle is the toughest dragon in the dragon world and more than lives up to its looks on the battlefield.
The Gronckle can be a slow, lazy, and cranky bulldog-like dragon; it has been known to fall asleep mid-flight, waking only when it plunges into the sea or crashes into a mountain.Because of its tremendous weight and small wings, it would seem impossible for them to fly. However, because the wings of a Gronckle beat at a speed similar to that of hummingbirds' or bees' wings, it is possible for one to sustain flight. In fact, a Gronckle can fly backward, sideways and even hover in place. Its tail can be mistaken for the head if little attention is paid. It is also prone to dragon acne. Because of its large stout body and clubbed tail, the Gronckle somewhat resembles an Ankylosaurus. They spend the majority of the day sleeping. It has huge jaws which it uses to hold food when carrying it to the dragon mound. It has a rather blunt nose horn and fairly stubby toe claws. Its legs are practically useless in battle, and due to its short tail it has a fairly small attack range.
The second is the Night Fury, a species of dragon that only appears in the movie adaptation of How to Train Your Dragon. Toothless is a Night Fury in the movie, in contrast with his original Common/Garden Dragon form in the book.
The Night Fury is the rarest and most intelligent species of dragon. It is small to medium-sized with a sleek, dark body that is almost black. It sometimes appears bluish and has faint lighter patterns similar to that of a manta ray. The Night Fury resembles an axolotl in general appearance and has two pairs of wings, two ear-like appendages on the back of its head to show its mood, a pair of yellowish-green, cat-like eyes and sharp retractable teeth. Unlike most dragon species, the Night Fury has a short neck and lacks any kind of horns. The Night Fury also seems to bear a striking resemblance to a gecko.
In flight, the Night Fury's wingspan is unrivaled- in a Riders of Berk episode, Fishlegs states that the Night Fury's wingspan is 48 feet- making it resemble some sort of jet plane. This allows it to fly faster, longer and further than any of the other dragon species. It uses the wing-like flaps on its tail to steer and maneuver, similar to an airplane rudder. As seen in the movie, a Night Fury will be incapable of flying if one of these flaps is missing or destroyed.
Night Furies are generally quite aggressive to any form of threat they find, similar to how the other dragons treat the Vikings of Berk. According to the Dragon Manual, the Night Fury is considered to be so aggressive that it is likened to the "unholy offspring of lightning and death itself". Toothless proves himself to be quite an advanced fighter when he manages to defeat a Monstrous Nightmare, one of the Vikings most feared enemies. He also quickly outmaneuvers and defeats Stoic the Vast, who is presumably the best dragon slayer in Berk. Also like its fellow dragons, Night Furies are seen to have a different personality when they are not threatened. They are curious creatures that attempt to understand new things they observe and are intelligent enough to recreate the actions that they see. Night Furies are fairly capable of communicating. Toothless does not have a very hard time getting his emotions noticed. Also, he seems to be fairly capable of understanding speech. The best evidence of this is when he makes a noise in agreement with Hiccup regarding the fact the the Red Death can fly. He also seems to understand when Hiccup orders him not to kill his father, Stoic the Vast.
The last one is the Terrible Terror, among the smallest of the dragons, but also one of the most feared. It loosely resembles the Common or Garden Dragon and is roughly the size of a small cat.
The Terror can crawl into Viking homes, sheds, outhouses and shacks, attacking when its prey is least expecting it. The only warning a Terror gives is the hissing sound it makes just before breathing fire. It is capable of such pinpoint accuracy with its flames that it can be considered the sniper of the dragon world.
Hiccup learns from Toothless that dragons are easily distracted by reflected light on the ground, similar to a cat, and uses this to his advantage to lure a Terror back into its pen during Dragon Training. He also learns that dragons are not as fireproof on the inside as one might think when Toothless spurts a fireball into a Terror's mouth for attempting to steal one of his fish. Before it leaves, Hiccup tosses it another fish and finds that Terrible Terrors are not as fierce as Vikings claim they are after it curls up beside him to sleep. Seeing this makes Hiccup realise that everything the Vikings know about dragons is completely wrong.
