Kukulkan's species

Kukulkan's species is a functionally extinct species of winged serpentine beings.

The last member of this species, Kukulkan, visited Earth in ancient times, giving rise not only to the Mayan deity that bears his name, but also to the Aztecs' Quetzalcoatl and the mythical Chinese dragon.

Biology
Members of this species are large serpentine creatures with a pair of feathered wings. They have a mane of purple feathers separating the green head from the red body, as well as blue feathers on their wings and tail. Their eyes have yellow sclerae. They have a single horn on their foreheads and fangs in their mouths. They can live for millennia.

History
Before mankind discovered fire, Kukulkan's species was destroyed by an unknown catastrophe, save for a lone survivor, Kukulkan, who traveled through space in a starship and collected specimens of fauna from several planets to keep him company. He kept his animals in cages, while providing them with virtual simulations of their natural habitats to keep them happy.

In his travels Kukulkan also met humanoids on several planets, but was always appalled by their violent, hateful ways. When he visited Earth, he decided to make an experiment and try to help the native Humans overcome their savage, warlike nature. To many cultures, Kukulkan acted as a mentor and harbinger of knowledge. When he left the planet, he left instructions for the many Human cultures to build a city, and told them that he would return when the city was completed. However, no single civilization had the complete plans for the city, as Kukulkan apparently expected them to collaborate in building it, which they never did.

In 2270, Kukulkan sent a probe to investigate what had become of humanity, and was disgusted to find that they were still warlike after all these centuries. However, Captain James T. Kirk convinced Kukulkan that he should allow humanity to develop on its own, rather than being guided.
