King Darkstalker was formerly a NightWing-IceWing hybrid, transformed by Kinkajou into a NightWing-RainWing dragonet at the end of Darkness of Dragons. He is the biological son of Arctic and Foeslayer, who met and fell in love in the Ice Kingdom and ran away together because Arctic's mother, Queen Diamond, would have never approved of their relationship. Because Arctic was an animus, Darkstalker also inherited this power, along with two powers from the brightest night: mind-reading and prophecy skills. These abilities combined made Darkstalker one of, if not the most, powerful dragon in Pyrrhia, which ultimately lead to his downfall; his partner, Clearsight, and his best friend, Fathom, betrayed him for the sake of the world, putting him in a permeant sleep under Agate Mountain with an enchanted moonstone bracelet. Over 2,000 years later, he was awakened when a passing comet caused an earthquake which broke his bracelet and allowed him to wake once again.
