Kukulkan was an ancient and long-lived lifeform who was the last of his species and had an impact on various ancient Earth cultures' beliefs and legends. He has also been identified with the lore of Quetzalcoatl, as well as the legend of the Chinesedragon. Kukulkan's visit to Earth is manifested in history by legends of a winged serpent creature that came from the sky bringing knowledge. These records were available in the library computer of the USS Enterprise. Despite his imposing appearance, he was benevolent.
