Thor (comics)
Thor, a founding member of the superhero group the Avengers, often battles his evil adoptive brother Loki, a Marvel character adapted from the Norse god of mischief. He is among Marvel's most powerful superheroes. Many recurring characters in his stories are based on Norse Mythology. Apart from this main superhero, Marvel features a number of characters based on him.
Óðr
In Norse mythology, Óðr (Old Norse for the "Divine Madness, frantic, furious, vehement, eager", as a noun "mind, feeling" and also "song, poetry"; Orchard (1997) gives "the frenzied one") or Óð, sometimes anglicized as Odr or Od, is a figure associated with the major goddess Freyja. The "Prose Edda" and "Heimskringla", written in the 13th century by Snorri Sturluson, both describe Óðr as Freyja's husband and father of her daughter Hnoss. "Heimskringla" adds that the couple produced another daughter, Gersemi. A number of theories have been proposed about Óðr, generally that he is somehow a hypostasis of the deity Odin due to their similarities.
