Sköll (One; who mocks) and Hati (One; who hates) are the names of two evil Jötnar (giants) presented in ancient Norse mythology. They are the sons of Fenrir and are constantly chasing Sól and Mani, the Norse gods who embodies the Sun and the Moon. They'll inevitably eat the two gods and this will start Ragnarök, the end of the world.
Biography[]
According to the first chapter Gylfaginning (in Old Norse: "The Beguiling of Gylfic or "The Deluding of Gylfi") of the 13th century Old Norse work of literature known as the Prose Edda or Younger Edda, Sköll and Hati are two brother giants in the form of wolves, sons of Fenrir and thus grandsons of Angrboda, born at the iron forest in the end of the world. The giantess herself were stated to give birth to numerous beast Jötnar (Jötnar whose natural form being animalistic monsters as opposed to their humanoid brethren), with wolf giant brothers' father and snake-like Jörmungandr pose considerable threat to the Gods of Asgard as much as the rest of Nine Worlds.
They are in a constant and tireless quest to eat Sól and Mani, those who are the Sun and the Moon respectively, and by doing so, Ragnarök will start.
Personality[]
As monstrous wolf-shaped giants, Sköll and Hati acts as true savage animals and embodiments of destructive universal forces. They only seek to bring chaos and massive destruction to the universe by eating the Sun and the Moon, eventually starting the "end" of the world.
The only redeeming quality is that they love their family. In fact it was the incarnations of their father, uncles, and grandfather that motivated them to bring Ragnarök.
