The Monstrous Nightmare is a Stoker Class dragon that is one of the most featured dragons. They also seem to have a nasty habit of setting themselves on fire. If you want to train them, a gentle hand on the snout for respect. If that doesn't work, slam their horns on the ground!


A Nightmare is usually purple or scarlet and possesses a long, snakelike neck and tail. Unlike some other breeds of dragon, it has no forelegs, and its ground-based locomotion is similar to that of pterosaurs; it can use its claw-tipped wings to "crawl" along the floor.

Despite their name, Monstrous Nightmares are known to have a softer side. In Dragons: Wild Skies, their favorite food are scented flowers. In several points of Dragons: Riders of Berk, Hookfang occasionally dozed off and was distracted by butterflies.

Viking children use their flaming eggs for rounds of Viking "hot potato". The winner is the child with the most blisters.

Fighting Description

As it is quick to anger, the Monstrous Nightmare can be counted on to be the first to arrive and the last to leave in a fight. Its signature attack strategy, known as the "Fire Jacket," is to engulf itself in flames (according Snotlout, by igniting spit it coats itself in prematurely), resulting in an intimidating offensive and defensive maneuver similar in appearance to napalm or other gel-based incendiaries. This dragon also has powerful jaws, sharp teeth and talons like meat hooks. It can also use its tail as a club.

According to Gobber the Belch, the best way to engage a Nightmare is to clamp its mouth shut, leaving it unable to open its enormous jaws, much like a crocodile (however, the rest of the dragon is free to do whatever it wants). In Heather Report Part II, Snotlout revealed that the Monstrous Nightmare enjoys its horns pinned to the ground, and Astrid was able to tame one by doing so.

By nature, the Montrous Nightmare is fearless and proud. Nightmares are some of the strongest dragons around and they know it. The best way to earn the trust of a Nightmare is simply to show it the respect it deserves. Placing a gentle hand on its snout and showing you are not a threat to it is the best way to go.

Monstrous Nightmares may be dangerous, but they sure are mischievous!

Monstrous Nightmares are very, very hard to train, they are very mischievous also. Monstrous Nightmares apparently can be trained either by hand on the snout, or having their horns slammed on the ground.
