The one on the far left, the black one.

He has black sclera, wings, skin, gums and teeth, everything but his iris, which is a brushed gold. Their blood is still red, but thicker and darker, making them able to survive in cold places. Hellion rely most on honor, respect and trust, fighting for all of it, and focusing primarily on physical strength. Their claws aren't nails, like on cats and humans, but bone, with strong tendons stretching from the wrist. Their jaws are stronger and open much wider than a human, their fangs long and thick. They can hear and smell much better than a human, and they have tail feathers that extend from their tail, the feathers connected by thick cartridge. They lack most feeling in their hands, but their tails and wings are very sensitive, and a weak spot for attack. They are capable of growls and roars and crocodilian sounding hisses, their language full of a combination of these things making it sound very savage.
