Night Fury

The Night Fury is a medium sized dragon that appeared in the How to Train Your Dragon series.

Overview
It is the fastest, intelligent, and rarest of the known species of dragons, as Toothless might be the last known member of his species. It is medium-sized with a sleek, dark body with black coloration. It has faint lighter patterns similar to that of a Manta Ray. Its body looks similar to a axolotl in general appearance and has two pairs of wings with a shape similar to a bat, two mobile, ear-like appendages on the back of its head that show its mood and help it hear, as well as other pairs around their jaw depending on their age.
