Dragon

Dragons are a species in Sebek: The Series. They originate from the Core of the Universes. No-one knows exactly where they came from or how they got to Earth, with some theories being that they originated from a faraway planet with some evolving to survive and travel in space, while other theories suggesting they evolved underground, away from anyone to see. Dinosaurs are said to be like the Neanderthal counterpart to dragons.

 Appearance 

The appearances of dragons varies heavily from breed and adaptations, but most have six limbs (Four legs, two wings) and are essentially just large reptiles. Some unique dragons may have multiple heads, look like more like raptors, anything could be possible.

They usually have some kind of anomalous properties that usually wouldn't be possible in nature, for example, many dragons are somehow able to fly despite the fact that their wings would not be able to suspend their body mass in the air, or violate the square-cube law. And even that is just scratching the brim. Dragons insist that this isn't the work of any magic.

 Abilities 

Dragon abilities also vary heavily. Other than being a large powerful reptile, they can have a variety of different abilities, the most common being some kind of breath attack.

However, dragons have an ability to get a second form, which can be anything resembling a human. This is acquired from healed dead bodies with no injury but devoid of any life or soul. They can turn to their second form at any time, and if their second form is killed, the dragon switches back to its normal form unharmed. Some dragons can stay 'dead' for a while without switching back. The second form usually regenerates after some time. However, it cannot regenerate if parts of its mass are missing, such as from erasure abilities, in which the dragon will have to get another second form.

Most dragons have durable scales, probably enough to withstand a pistol bullet or two, and definitely enough to withstand sword strikes. However, every dragon has a weakness, depending on the individual.
