Monstrous Nightmare

The Monstrous Nightmare dragon is the most aggressive and powerful of the dragons. They also have a habit of lighting themselves on fire. The locomotion of the Monstrous Nightmare is similar to that of pterosaurs. By unoffical Viking law, only the chief, or the son of the chief can own one. They are the first to arrive and the last to leave in a fight. One of their attack strategies is to coat there itself in their sticky gooey fire. The most common colors for a Monstrous nightmare are purple and scarlet. They were used for initiation tests for young Vikings before the Vikings befriended the dragons. Semi-rare.

Appearance
Monsterous Nightmares have long, snakelike heads and tails. When it's mouth is clamped shut, they are unable to open their jaws. The rest of the dragon, however, may do as it pleases. They have large, bat-like wings with spiny edges and four horns jutting backwards. Their claws and teeth are long and lethal. Much like a pterosaur, their wings are tipped with claws, and they walk in a similar manner when on the ground. The lower jaw of the Nightmare is longer then it's top jaw.
