Dark wyverns are maybe the biggest dragons the world has ever seen. They can reach enourmous sizes, and a wingspan that's the longest of every living creature known. They live millenia, and the more they age, the more they become intelligent and smart, as well as bigger. As smart and cunning as an evil dragon can be, these creatures have proven the most ferocious dragons ever. They're enourmus killing machines that attacks with torrents of fire and sharp claws. They are nocturnal, as showed by the dark colors of theys scales, and are good flyers, able to fly for days without tiring and manouver very well.
-Enhaced senses: dark wyverns have perfect visions, that allow them to see two times better than an elf by day, and four times by night. They can so see their prey from far above it. They can even 'zoom' on certain targets. They got very sensible hearing and an enhaced sense of smell, so that they can detect prey far before seeing it, even with theyr miracoulus sight;
-Fire breath: Like all dragons, dark wyverns can breath fire. They spit out their flames thanks to the energy of their ever-burning fury. These creatures breath out entire torrents of fire, that can extend for hundreds of meters. At the occasion, they can spit fireballs;
-Claws: dark wyverns have big, very resistant wings, and they do not only use them to fly. even when closed, the dragons can use thair wings as weapons, using the powerful and sharp claws on the wingtips;
-Mace-tail: dark wyverns have a very long tail, on whose ends lays a strong spiked mace made out of very heavy bones. When they swing this mighty weapon, they can crush entire blocks of buildings without feeling the slightest pain;
-Dragon scales: as all dragons, dark wyverns are covered in thick scales, that allow them to shrug off most attacks without real damage;
-Wings of darkness: dark wyverns have the ability to release big clouds of smoke by flapping theyr wings. These clouds can reach enourmous size, enought to hide the dragon's massive bulk. The dragons are perfectly able to see and breath through the smoke;
